Elkhart Supply 41274 BestPEX 1/2 in x 20 ft Blue PEX-B Tubing

The Elkhart Supply BestPEX 41274 is a 1/2-inch diameter, 20-foot straight-length section of PEX-B (cross-linked polyethylene) tubing in blue — the industry-standard color designation for cold water supply lines. Manufactured by Elkhart Supply Corporation, a trusted name in plumbing and RV supply products since 1949, this tubing is engineered for reliable performance in residential, manufactured housing, and RV fresh water plumbing systems.

PEX-B tubing offers a cost-effective and highly practical alternative to rigid copper or CPVC pipe. Its flexible nature makes routing through walls, floors, and tight spaces straightforward, while its resistance to scale buildup and corrosion ensures long-term reliability.
