Sharkbite UAB134LFZ Pex-a Mnpt Adapter

Product Description

The SHARKBITE UAB134LFZ is a PEX-A male NPT (MNPT) adapter designed to connect PEX-A tubing to threaded pipe fittings in residential and light commercial plumbing systems. This fitting bridges PEX-A expansion-style tubing to standard male national pipe thread connections, allowing transitions into valves, manifolds, and threaded ports without soldering or crimping. The adapter is sold individually and weighs approximately 0.192 pounds. Licensed plumbers and experienced plumbing technicians are the primary installers for this type of fitting.

This adapter is suited for potable water distribution systems, radiant heating supply and return lines, and other plumbing applications where PEX-A tubing must terminate at a threaded connection point. It is appropriate for both new construction rough-in work and retrofit installations where threaded transitions are required. The fitting is compatible with PEX-A expansion-style installation methods, which require an expansion tool and PEX-A expansion rings prior to connection.

Key Features

• PEX-A compatible design for use with expansion-style PEX installation tools and rings
• MNPT threaded end transitions to standard male national pipe thread fittings
• Lead-free (LFZ) construction suitable for potable water applications

Installation Notes

Installation should be performed by a licensed plumber in accordance with local plumbing codes and IPC guidelines. Shut off the water supply and depressurize the line before beginning any fitting work. PEX-A expansion adapters require a compatible PEX-A expansion tool and appropriately sized expansion rings - do not attempt to install using crimp or clamp methods. Verify thread engagement and check for leaks before returning the system to service.
