Sharkbite UAB334LFA Pex-a Drop Ear 90 Degree Elbow 1/2 in

Product Description

The SHARKBITE UAB334LFA is a 1/2-inch PEX-A by 1/2-inch female NPT brass drop ear 90-degree elbow fitting designed for potable water distribution systems. Built from lead-free, dezincification resistant brass, this expansion-style fitting connects PEX-A pipe to a threaded female NPT port while also providing a mounting ear for securing the fitting to a wall or framing surface. Installation requires a PEX expansion tool and compatible expansion rings. This fitting is intended for licensed plumbers and experienced trade professionals working with PEX-A piping systems in residential and light commercial construction or retrofit applications.

This fitting is suited for drop ear elbow applications where a PEX-A supply line terminates at a wall-mounted fixture connection, such as a shower arm, tub spout, or toilet supply. The 90-degree configuration redirects flow from the in-wall pipe run to a forward-facing female NPT outlet. The mounting ear allows the fitting to be fastened to framing or blocking before drywall installation, stabilizing the connection point and reducing stress on the joint. It is sold in a package of 12 units, making it appropriate for multi-unit rough-in work.

Installation Notes

Installation must be performed using a compatible PEX expansion tool — do not attempt to connect this fitting without expanding the pipe and ring.
