VEVOR offers a reliable line of PEX pipes for plumbers, contractors, and committed do-it-yourselfers working on home and small-business projects. This collection includes oxygen-barrier PEX tubing, non barrier PEX tubing, and a range of PEX pipe sizes for domestic water supply, radiant heating, and hydronic systems. VEVOR PEX lines work consistently well at reasonable prices, whether you are roughing in a new bathroom or putting in an in-floor heating system.
Do you need PEX tubes, PEX pipe, oxygen-barrier PEX tubing, or PEX tubing without a barrier? With the right PEX pipe, fittings are faster and more reliable than with stiff copper or CPVC pipes. We make VEVOR PEX lines from cross-linked polyethylene, which is strong enough to withstand pressure, temperature changes, and long-term use in demanding plumbing and heating systems. Today, find the type and size of tubing you need for your job.
The most important thing to do in any plumbing or heating work is to choose the right type of PEX pipe. VEVOR offers both the main types of PEX pipe and tubing for specific uses. Knowing the difference between barrier PEX and non-barrier PEX helps workers choose the right product and avoid future performance issues.
When oxygen-shield PEX tubing is made, an additional EVOH layer is glued to the outside of the tube. This layer prevents oxygen from entering the water inside the pipe through the wall. When oxygen enters a closed-loop heating system, it corrodes metal parts such as radiators, boilers, pumps, and pipes. Using oxygen-barrier PEX tubing in these systems extends the lifespan of the attached metal parts.
VEVOR oxygen barrier PEX tubing is color-coded red and blue for supply and return lines. This makes it easy to set up systems and fix problems. Produced according to ASTM F876 and F877 standards, which means it meets well-known performance standards for resistance to pressure and temperature. Standard operating values cover temperatures and pressures up to 100 PSI and 200 degrees Fahrenheit, which covers the typical operating range for most residential radiant and hydronic heating systems.
Oxygen barrier PEX tubing is generally preferred for closed-loop systems with ferrous metal parts, radiant floor heating, and baseboard heating loops. If you use non-barrier tubing in these situations, most boiler and pump guarantees will not be valid. VEVOR oxygen barrier PEX tubing comes in coils that are 100 feet to 500 feet long. This lets installers buy the right amount of tubing for any size job without wasting too much or joining too many pieces together.
For potable water supply lines in homes and small businesses, non-barrier PEX tubing is a common choice. If you don't add the EVOH oxygen barrier layer, non-barrier PEX tubing is safe for drinking water and meets NSF/ANSI 61 certification standards for potable water applications. Barrier and non-barrier VEVOR PEX tubing are both made from the same cross-linked polyethylene base material. They both work well at the same pressure and temperature in water supply uses.
There are three types of non-barrier PEX pipes: PEX-A, PEX-B, and PEX-C. Each is made using a different cross-linking process. The most flexible type of PEX is PEX-A, which also doesn't kink easily during installation. The most common type is PEX-B, which has a good mix of flexibility, pressure rating, and price. It's less usual to use PEX-C in home plumbing because it's the stiffest grade.
Cold and hot water supply lines, fixture connections, and branch runs from main supply manifolds can all use VEVOR non-barrier PEX tubes. The tubing works with all common PEX fittings and joining methods, including crimp, clamp, and expansion systems. Cross-linked polyethylene expands under freezing pressure rather than splitting, reducing the likelihood of pipe bursts in cold areas. Copper or rigid plastic pipes do not handle freeze conditions as well as non-barrier PEX pipes.
To make PEX pipe, high-density polyethylene is cross-linked, strengthening the molecules and making them more heat-resistant. Cross-linking gives the material thermoset-like properties. This means that even at high temperatures, PEX tubing keeps its shape and pressure rating, while regular polyethylene would melt and bend.
Manufacturers of VEVOR PEX pipe tubing ensure it meets ASTM F876 and F877 standards for material composition, pressure rating, and measurement accuracy. These guidelines govern tolerances for wall thickness, the consistency of the inside diameter, and long-term performance under hydrostatic pressure. For solid-fitting connections, it's important that the wall thickness remains the same. When the wall thickness is too thin or too thick, fitting leaks can occur that are hard to find after the system is pressurized and concealed.
At 80 PSI, many PEX tubing products are rated to handle water up to 200 degrees Fahrenheit. At lower temperatures, it can handle higher pressures. Uses for cold water supplies at normal home pressures of 40 to 80 PSI are well within the material's performance range. The smooth interior of VEVOR PEX pipe tubing reduces friction loss and prevents scale buildup over time. This keeps flow rates steady over years of use, without the mineral-deposit problems that come with copper pipe in hard-water areas.
Manufacturers make PEX tubes in red, blue, and white to help workers keep plumbing and heating systems organized while they're working. Hot-water supply lines and heating-system feed loops use red PEX tubing. Cold-water supply lines and heated return loops use blue PEX tubing. For both uses, white PEX tubes are popular in systems with a central distribution point and manifolds.
The color coding doesn't change the tube's performance grade or the materials it's made of. All three VEVOR PEX tube colors can withstand the same pressure and temperature, and they all work with the same fittings and connection methods. Picking a color is just for organization, and it helps plumbers and inspectors find lines quickly during installation, inspection, and upkeep.
Along the length of a VEVOR PEX tube, there is identification printing that shows the tube size, material grade, pressure number, and any certifications that apply. These markings are designed to remain readable for the life of the system. They contain all the necessary information for compliance with inspection requirements. By using clear identification marks, installers and building inspectors can easily keep track of the system and avoid using the wrong tube type.
Picking the right size PEX pipes for a plumbing or heating job is just as important as picking the right type. Standard sizes of VEVOR PEX lines make them suitable for typical home and light business uses. Picking the right diameter ensures the system has the correct flow rate, fits the fittings correctly, and meets the plumbing code standards for each part.
Outside diameters of VEVOR PEX pipes are available in the most popular sizes for home plumbing, including 3/8, 1/2, 3/4, and 1 inch. Based on the flow needs at that point, each size is best suited to a different part of the plumbing system.
People use the 3/8-inch size for short fixture supply lines where there isn't much room and flow demand is low. In residential plumbing, the 1/2-inch diameter is the most common. It can handle supplies for individual fixtures, branch lines, and short runs from manifolds. The 3/4-inch size is good for connecting water heaters, carrying main supply lines, and trunk lines that feed multiple outlets. It can also handle connections for water heaters that need higher flow rates. People use the 1-inch size for large-diameter trunk lines and major supply entry points in multi-story buildings or homes with high demand.
If you choose the right sized PEX lines, you can avoid pressure drops at fixtures and ensure the system has enough flow when multiple outlets are in use simultaneously. A common construction mistake is making supply lines too small, resulting in weak flow at showers and faucets during high-demand periods. VEVOR PEX pipes come in standard coil lengths for all diameters, making it easy to buy the right amount for each part of the system.
For radiant floor heating systems, PEX pipe tubing is the most common choice. The tube is either pressed into concrete slabs or stapled under subfloor panels to form a loop. From a heater or heat pump, warm water flows through the loop and evenly distributes heat across the floor. VEVOR oxygen-barrier PEX tubing is an appropriate choice for most radiant floor heating systems with metal components.
A radiant floor system's heat generation is based on the loop length and tube spacing. Most home installations leave 6 to 12 inches of space between each tube run. The spaces are closer together in areas that need more heat, such as bathrooms or rooms with lots of glass. To keep the flow even across the system, each loop is typically only 300 feet long. VEVOR PEX pipe tube in 3/8-inch and 1/2-inch diameters is what radiant floor heating loops are most often made of.
Baseboard convector heating, snow-melt systems built into driveways or walkways, and household hot-water recirculation loops are among the other common uses for PEX tubing. Flexible PEX pipes are much faster to install in these situations than rigid pipes because they require less work and fewer joints.
VEVOR PEX pipes come in a wide range of sizes and types to fit all plumbing and heating needs in homes and small businesses. They include oxygen barrier and non-barrier tubes. You can buy barrier and non-barrier PEX tubes, PEX pipe, and other products that meet ASTM and NSF standards at prices that are good for both contractors and DIYers. Check out all of VEVOR PEX pipes and tubes to find the right option for your project.
An EVOH layer on oxygen-shielded PEX tubing prevents oxygen from entering closed-loop heating systems and from rusting metal parts. NSF/ANSI 61 certifies non-barrier PEX tubes for use with potable water. For heating systems, you should always use barrier tubing. For drinking water supply lines, you should use non-barrier tubing.
If you need to give hot or cold water, VEVOR PEX pipes can do it. The tube can withstand pressures up to 100 PSI and temperatures up to 200 degrees Fahrenheit. To keep the system organized and simple to find, use blue PEX tubes for cold lines and red PEX tubes for hot lines.
For major supply lines serving many fixtures or the whole house, use 3/4-inch or 1-inch PEX pipe. For branch lines to each outlet, use 1/2-inch PEX. When you size your main trunk lines, you prevent the pressure drop that occurs when multiple outlets are running at the same time, which happens a lot in home plumbing systems that are too small.
It is possible to use normal crimp rings, clamp rings, and expansion-style PEX fittings with VEVOR PEX pipes. Make sure the PEX grade is compatible with the connection method, and that the fitting type is compatible with the right tool. Pipes made of PEX-A work with expansion joints, while pipes made of PEX-B and PEX-C work with crimp and clamp systems.
