Sharkbite UAB526LFA Pex-a Fnpt Swivel Adapter

Product Description

The SHARKBITE UAB526LFA is a PEX-A FNPT swivel adapter designed to connect PEX-A tubing to female NPT threaded fittings in residential and light commercial plumbing systems. The swivel design allows the threaded end to rotate during installation, reducing torque stress on the connection and making it easier to thread into fixed fittings without twisting the PEX line. This type of adapter is a standard component in potable water distribution, hydronic heating, and radiant floor systems. Installation is performed by licensed plumbers or experienced plumbing contractors working with PEX-A piping systems.

This swivel adapter is suited for applications where PEX-A tubing transitions to NPT-threaded valves, manifolds, shut-off valves, or fixture supply connections. It is commonly used in new construction plumbing rough-ins and in remodel work where existing NPT-threaded components are being integrated into a PEX-A distribution system. The FNPT end accommodates standard tapered pipe thread fittings found throughout residential and light commercial plumbing installations.

Key Features

• PEX-A compatible construction supports expanded PEX connection method for reliable, long-term performance
• Swivel FNPT end reduces installation torque stress and simplifies threading into fixed fittings
• Female NPT thread accepts standard tapered pipe thread connections at valves, manifolds, and fixtures
• Lightweight at 0.125 pounds, suitable for tight installation spaces
• Sold individually, allowing precise quantity purchasing for each connection point

Compatibility

Designed as an OEM-style transition fitting for PEX-A plumbing systems connecting to standard female NPT-threaded components in residential and light commercial applications.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and the International Plumbing Code (IPC). Shut off the water supply and relieve system pressure before making any connections. PEX-A expansion fittings require the proper expander tool sized to the tubing diameter before inserting the fitting. Do not overtighten the FNPT swivel connection; hand-tight plus the appropriate number of turns per code and fitting manufacturer guidance is sufficient to achieve a leak-free seal.
