Sharkbite U4248LFA 1/2 in Polybutylene Conversion Elbow Fitting

Product Description

The SharkBite U4248LFA is a 1/2 inch push-to-connect brass 90-degree elbow fitting designed to convert polybutylene pipe to copper, CPVC, or PEX pipe in any combination. No soldering, clamps, unions, or glue required. Stainless steel teeth grip the pipe on insertion, and a specially formulated O-ring compresses to form a watertight seal. The fitting can also be rotated after assembly to simplify installation in confined or awkward spaces. Certified for potable water supply and hydronic heating applications, this fitting is sold in a package of 6 units.

The U4248LFA is suited for residential and light commercial plumbing work where polybutylene supply lines require transition to modern pipe materials. Typical applications include retrofitting or repairing existing polybutylene distribution systems by transitioning into copper, CPVC, or PEX. The 90-degree angle makes it practical for direction changes at walls, floors, or fixture connections. Licensed plumbers handling polybutylene pipe replacement or repair will find this fitting useful in both open-wall and tight-access scenarios.
