EFIELD 1-inch PEX-B 100 ft Blue Tubing - NSF Certified for Potable

Our review of the EFIELD 1-inch PEX-B 100 ft blue tubing finds it best suited to builders, plumbers and homeowners who need a long length of NSF certified potable water pipe that resists common chemical additives. The single biggest reason to buy is reliability: this tubing comes directly from a major PEX systems manufacturer and is certified for drinking water, which means users get a hygienic, chemical resistant line that should not impart taste or odor when installed properly.

Key Features

• NSF certified: Certification ensures the tubing meets contemporary American drinking water standards and is suitable for potable water use.
• Manufacturer direct: Supplied by a prominent PEX systems maker, so buyers can expect consistent quality and specification control compared with generic sources.
• Chemical resistance: The inner PEX material resists chlorine and chloramine additives often present in municipal supplies, helping protect the tube from premature degradation.
• Hygienic performance: The product is described to produce no unpleasant smell or taste, which matters for both hot and cold water lines.
• Length and diameter: A full 100 ft roll of 1 in tubing provides long runs for new builds or multiple branch runs without many couplings.

Who It's For

The tubing is ideal for professional plumbers, contractors and serious DIYers fitting potable hot and cold water systems in new builds or major renovations who want a long continuous run and NSF assurance of water safety. Its 1 in diameter and 100 ft length make it useful for long distribution runs or manifold-fed systems where fewer joints are preferred.

It is less well suited to small, one-off repairs where short lengths would be easier to handle, or projects requiring flexible immediate straightening without recoil - some users report occasional handling or straightening quirks that can make installation slower in tight spaces.

Pros & Cons

Pros

• NSF certification provides confidence for potable water installations and ensures hygienic performance.
• Good chemical resistance to chlorine and chloramine preserves material integrity in treated water systems.
• Manufacturer-supplied tubing tends to be consistent in quality and length, offering value for long runs.
• 100 ft roll reduces the number of couplings and fittings needed on long projects.

Cons

• Some customers report mixed ease of installation, particularly with tube straightening and clamping in certain setups.
• The 1 in diameter and long roll can be stiff to maneuver in confined areas compared with shorter sections.
