VEVOR PEX Pipe, 1 Inch x 500 FT

VEVOR’s non-oxygen barrier PEX-B tubing features a 1.125-inch outer diameter, a 0.875-inch inner diameter, and a 0.07-inch wall thickness. The 500-foot coil is designed for large-scale plumbing tasks, and the material is chosen to minimize contamination risks in home water systems and radiant heating layouts. It supports -40°F to 203°F operation and maintains a 100 PSI rating at 180°F, making it suitable for year-round reliability in varied climates.
The tubing offers a minimum bend radius around 7 inches, enabling installation in tight spaces, including underground or above-ground settings. The pipe includes a cutter for quick, precise cutting, which is helpful in complex layouts where fittings need to be minimized and run times reduced.
SharkBite 1 Inch x 500 Feet Red PEX-B

This red PEX-B coil is tailored for hot and cold potable water systems, providing flexibility for long runs and reducing the need for elbows and fittings. The tubing can bend around corners and works with expansion (F1960), push-to-connect (ASSE 1061), and various barb fittings (ASTM F2159, F1807). It’s also described as suitable for direct burial, including under concrete, which is advantageous for both residential and commercial installations.
VEVOR PEX Pipe, 1 Inch x 500 FT Red B Pipe

This red 1-inch PEX-B tubing emphasizes non-barrier construction with a 500-foot length designed for radiant heating, RV plumbing, and general water distribution. It shares a 7-inch bend radius and a 0.07-inch wall thickness, offering resilience against typical day-to-day pressure changes. It remains flexible, crack-resistant, and designed for both underground and above-ground uses, with compatibility for multiple installation methods.
Pex-A 1 Inch x 500 Feet (Non-Barrier) SUPPLYGIANT

SUPPLYGIANT’s Pex-A tubing represents a premium, highly flexible option in a non-barrier variant, with emphasis on minimizing fittings through its superior bend radius. This 1-inch PEX-A coil is designed for easier installation of radiant floor heating and potable water lines. It complies with ANSI, ASTM, CAN/ULC, and CSA standards, and is compatible with expansion (F1960), crimp (F1807), and clamped connections. The 500-foot length suits longer runs and reduces splicing complexity.
Pex-A Tubing 1 Inch x 500 Ft Red SUPPLYGIANT

This red Pex-A coil offers expansion-tolerant performance with a focus on flexible installation for potable water and radiant heating systems. It highlights the same ANSI/ASTM/compliance framework and compatibility with expansion, clamped, and sleeve methods, making it suitable for a range of retrofit and new-construction projects where bendability and rapid setup are valued.
Buying Guide: Key Purchase Considerations
Selecting the right 500-foot, 1-inch PEX coil depends on project specifics and climate. Consider these factors:
- PEX Type: PEX-A is the most flexible with the tightest bend radius, ideal for complex routes and radiant heating. PEX-B is a strong, reliable option with good chemical resistance for potable water.
- Barrier vs Non-Barrier: Non-oxygen barrier PEX reduces cost but may require additional protection in certain environments. Oxygen barrier variants help deter corrosion in hydronic systems with metal components.
- Temperature and Pressure Ratings: Ensure the tube temperature and pressure ratings align with your system’s design, especially in radiant heating where high temperatures may occur.
- bend Radius: A smaller bend radius supports installations in tight spaces but confirm the minimum bend radius for your chosen product (commonly around 7 inches for 1-inch tubing).
- Compatibility: Check fittings and joining methods (F1960 expansion, F1807 crimp, ASSE 1061 push-to-connect, clamps, or sleeves) to ensure integration with existing hardware.
- Color Coding and Applications: Red tubes typically indicate hot water lines, white or neutral colors often denote cold water; color should align with your installation plan and local codes.
- Delivery Length and Availability: A 500-foot coil reduces joints on long runs, but ensure your project can accommodate a single, continuous length or plan for splicing where required.
Performance and Durability Considerations
All listed products are designed to withstand extreme temperatures and pressures typical in residential plumbing and radiant heating. The combined benefits include:
- Freeze protection for outdoor installations and crawlspaces.
- Resistance to chemical contaminants, improving long-term water quality in potable systems.
- Ease of cutting and shaping to reduce installation time and labor costs.
- Compatibility with a wide range of fittings and connection methods for flexible project planning.
Installation Perspectives
For home builders and DIY enthusiasts, a 500-foot coil minimizes the number of connections, which can reduce potential leak points. Contractors may prioritize PEX-A for its bend radius in complex layouts, while PEX-B offers cost-effective reliability in straightforward runs. When routing lines for radiant floor heating, consider the paneling layout and floor thickness to optimize heat distribution and response time.
Climate and Environment Considerations
Outdoor and underground installations require careful planning to avoid exposure to UV light and potential physical damage. Ensure burial depths align with local codes and use appropriate protective sleeves or conduit when necessary. In freezing climates, verify insulation strategies around exposed runs to maximize energy efficiency and prevent heat loss.
This guide highlights five viable options for a 500-foot, 1-inch PEX coil, balancing flexibility, durability, and installation ease. Selecting the right tubing will depend on your specific system design, local regulations, and long-term maintenance goals.
