Sharkbite UC139LFA Barb X Mnpt Male Adapter 3/4x1 in

Product Description

The SHARKBITE UC139LFA is a 3/4-inch barb by 1-inch male NPT (MNPT) threaded adapter machined from lead-free brass. It connects a barbed hose or tubing end to a standard male NPT threaded fitting without soldering, gluing, or clamping. The push-to-connect side uses stainless-steel gripping teeth and a compressed O-ring to form a watertight seal the moment pipe is inserted. Licensed plumbers and experienced DIYers install this fitting when transitioning between barbed tubing and threaded pipe connections in residential and light commercial water supply systems.

This adapter is suited for potable water supply lines where a barbed connection must transition to a 1-inch male NPT threaded port. The lead-free brass construction meets requirements for drinking water contact. The fitting can be rotated after installation, which is useful in confined spaces or tight mechanical chases. Package quantity is 6 units per package, making it practical for multi-fixture rough-ins or service calls requiring several transitions on the same job.

Installation Notes

Installation is performed by licensed plumbers or qualified trades working under applicable IPC or local plumbing code requirements. Shut off and depressurize the water supply line before making or breaking any fitting connection. Ensure pipe ends are cut cleanly and deburred before inserting into the barb end. Inspect the O-ring for seating and verify the NPT thread is engaged fully and sealed with appropriate thread sealant or tape before restoring pressure.
