SharkBite 1 in x 300 ft White PEX-B PEX Pipe - Flexible Plumbing

Our review of the SharkBite 1 in x 300 ft White PEX-B coil finds it well suited for pros and DIYers who need a long, flexible run of potable water tubing with fewer fittings. The single biggest reason to buy is its flexibility and length: the 300 ft coil lets installers cover long distances with fewer joints, which saves time and reduces leak risk, and the PEX-B construction balances durability with bendability for both hot and cold water systems.

Key Features

• Flexible PEX-B tubing: The long 300 ft coil supports extended runs and reduces the number of fittings required, lowering installation time and potential leak points.
• Easy installation: The tubing bends around corners without elbows and works well with push-to-connect fittings, simplifying routing in tight spaces.
• Compatibility with common fittings: Works with PEX expansion, push-to-connect, plastic barb and brass barb fittings for versatile connection options on job sites.
• Durable and UV-tolerant: Cross-linked polyethylene construction resists kinks and is rated for six months of UV exposure, enabling temporary outdoor staging and direct burial.
• Rated performance: Service limits include operation to 200 degrees F at 80 PSI and 160 PSI at lower temperatures, giving confidence for typical potable water applications.

Who It's For

The SharkBite 1 in x 300 ft PEX-B is ideal for plumbers, irrigation contractors, and experienced DIYers who need long continuous runs for potable hot and cold water lines or irrigation mains. Its flexibility and length reduce fittings and joints, which is particularly useful in basements, long wall runs, and outdoor irrigation where fewer transitions are desired.

Those who should look elsewhere include installers who require pre-insulated tubing, very rigid pipe for specialized structural routing, or projects that demand permanent full UV exposure beyond six months without protection. Also, if you need multiple different diameters, buying coils sized to each run may be more convenient than a single large coil.

Pros & Cons

Pros

• Long 300 ft coil reduces fittings and installation time for long runs.
• Flexible PEX-B design bends around corners, cutting the need for elbows and extra fittings.
• Compatible with a wide range of fittings including push-to-connect and expansion systems.
• Durable cross-linked polyethylene construction resists kinks and tolerates short-term UV exposure.

Cons

• Coil stiffness is mixed among users, so handling a full 300 ft coil can require effort and may feel stiff compared with smaller diameters.
