SharkBite 1 Inch x 300 Feet White PEX-B
This White PEX-B coil is designed for hot and cold potable water systems. Its 1 inch by 300 feet length supports longer runs with fewer fittings, reducing installation time and potential leak points. It is compatible with expansion (F1960), push-to-connect (ASSE 1061), and various barb fittings. Suitable for direct burial, including under concrete. Best for contractors or DIYers planning extended runs with minimal joints.
Best for: larger home or commercial layouts needing fewer connections. Alternative: choose a different color for system zoning to visually separate lines. Caution: ensure proper expansion or connection method with your chosen fittings to avoid leaks at joints.
VEVOR PEX Pipe 1 Inch x 500 FT White
VEVOR’s 1 inch PEX-B white tubing comes in a substantial 500-foot coil, ideal for large residential or light commercial projects. It offers a 1.125 inch outer diameter and a 0.875 inch inner diameter with a 0.07 inch wall, designed for durability and reliability. It’s flexible with a 7-inch bend radius, easy to cut, and compatible with common fittings. Best for expansive piping runs where a long continuous line is advantageous.
Best for: projects needing extensive runs with fewer joints. Caution: verify bend radius in tight spaces to avoid kinks during installation.
Supply Giant QGX-X1100 PEX Tubing 1 Inch x 100 Feet
Supply Giant QGX-X1100 PEX Tubing offers a cost-effective option for potable water use. It is a 1-inch, white, non-barrier PEX-B tubing suitable for a range of plumbing installations. It supports standard PEX push-to-connect and crimp fittings and meets NSF/ASTM standards. Best for budget-conscious projects that still require reliable PEX-B performance.
Best for: price-sensitive applications with standard piping needs. Caution: shorter coil length means more fittings for longer runs, which could increase installation time in larger systems.
SharkBite 1 Inch x 300 Feet Blue PEX-B
This Blue SharkBite PEX-B coil is designed for hot and cold potable water systems, with 1 inch by 300 feet length to support longer runs while keeping fittings to a minimum. It expands slightly when frozen and contracts after thawing, aiding freeze tolerance. Compatible with expansion (F1960) and various barb fittings. Best for projects needing color-coded line identification or cold-line emphasis.
Best for: easy identification of cold water lines and longer routes. Caution: color coding should align with overall plumbing plan to avoid confusion in multi-line installations.
VEVOR PEX-B Pipe 1 Inch x 500 FT Blue Non-Oxygen Barrier
VEVOR’s blue non-oxygen barrier 1 inch PEX-B tube is designed for radiant heating, hydronic cooling, and general water plumbing. It offers a 7-inch minimum bend radius, high flexibility, and strong sealing characteristics. It withstands -40°F to 203°F and supports various pressure ratings depending on temperature. Best for underfloor heating or outdoor installations needing reliable performance in extreme conditions.
Best for: radiant heating or challenging environments with temperature variability. Caution: confirm compatibility with local code requirements for non-oxygen barrier lines in your area.
Buying Guide: 1 Inch PEX-B Tubing For Your Project
What to consider when choosing 1 inch PEX-B?
Length needs: For long runs, coils like 300–500 feet reduce fittings and potential leak points. If space allows, a larger coil can save time on big jobs.
Non-oxygen barrier vs oxygen barrier: Non-oxygen barrier PEX is common and adequate for many indoor plumbing tasks. Consider barrier types if your project involves long exposure or harsh conditions.
Temperature and pressure tolerance
Check the maximum operating temperature and pressure. Most PEX-B tubing handles typical residential loads, but radiant heating or outdoor exposure can demand higher limits.
Fittings compatibility
Ensure compatibility with expansion fittings (F1960), push-to-connect (ASSE 1061), and relevant barb fittings (ASTM F1807/F2159). This affects installation speed and reliability.
Flexibility and bend radius
A larger bend radius helps navigate tight spaces without kinking. A typical minimum bend radius is around 7 inches, but confirm on the product page for exact figures.
Applications and installation environment
Direct burial suitability, indoor radiant heating, and outdoor exposure all influence selection. Some products are explicitly noted as freeze-tolerant or UV resistant, which matters for exterior or unprotected runs.
Cost and coil availability
Coil length and price often drive choice in larger projects. Compare per-foot costs and consider future expansion or repairs when selecting coil length.
FAQ
What does PEX-B mean?
PEX-B refers to cross-linked polyethylene type B tubing, a common form of PEX with a specific manufacturing method that offers durability and flexibility for plumbing.
Is blue or white PEX-B better?
Color mainly helps with line identification. White and blue are both PEX-B; use color to distinguish hot vs cold lines or different zones in a project.
Can PEX-B be buried underground?
Many PEX-B products are rated for direct burial, including under concrete. Always verify the product’s suitability for burial and follow local code requirements.
Which fitting types should I use with PEX-B?
Fittings include expansion (F1960), push-to-connect (ASSE 1061), plastic barb (ASTM F2159), and brass barb (ASTM F1807). Match the pipe and fitting type for a secure connection.
What is the advantage of a long coil?
A longer coil reduces the number of joints, lowering potential leak points and installation time on extended runs.
