Fernco 642xg3 Pex Crimp Brass Elbow 90 Degree 3/4 in

Product Description

The FERNCO 642xg3 is a 90-degree PEX crimp brass elbow designed for 3/4-inch by 3/4-inch connections in potable water and hydronic systems. Constructed from lead-free brass, it meets requirements for drinking water applications. The fitting accepts standard PEX crimp rings and is installed using a PEX crimp tool, making it a common choice for licensed plumbers and experienced installers working with cross-linked polyethylene tubing. Its compact profile measures 1.35 inches in length, 1.4 inches in width, and 0.7 inches in height, fitting into tight spaces within wall cavities and mechanical chases.

This elbow is suited for residential and light commercial plumbing installations where a 90-degree directional change is required in a PEX run. Typical applications include domestic hot and cold water distribution, radiant heating loops, and manifold branch connections. The lead-free brass construction makes it appropriate for potable water service lines where local codes require lead-free materials.

Installation Notes

Installation requires a calibrated PEX crimp tool and appropriately sized copper or stainless crimp rings. Shut off the water supply and relieve system pressure before cutting into any existing line. Follow local plumbing code requirements, including IPC guidelines, for PEX fitting installation and inspection. Verify crimp ring seating with a go/no-go gauge after crimping to confirm a leak-free connection.
