Sharkbite UAB530LFA Pex-a Fnpt Swivel Adapter

Product Description

The SHARKBITE UAB530LFA 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 fitting to rotate during installation, reducing torque on the tubing and making it easier to achieve a proper connection in tight spaces. This adapter is suited for potable water distribution, hydronic heating supply lines, and similar closed-loop or domestic water applications. Licensed plumbers and experienced plumbing technicians are the primary installers for this type of fitting.

This swivel adapter is used in new construction and retrofit plumbing projects where PEX-A tubing interfaces with threaded fixtures, valves, or manifold ports. The FNPT thread configuration makes it compatible with a wide range of standard threaded components found in residential plumbing rough-in work and fixture connections. Its compact form factor suits installations in wall cavities, under-sink connections, and mechanical room piping runs where working clearance is limited.

Key Features

• PEX-A tubing compatibility for use with expansion-style fittings
• Female NPT swivel thread allows rotation during makeup to reduce tubing stress
• Compact adapter profile suited for confined plumbing spaces
• Designed for potable water and hydronic plumbing applications

Compatibility

Designed as an OEM-style replacement and standard installation fitting for PEX-A plumbing systems with female NPT threaded connection points.

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 relieve system pressure before making any connections. Use the appropriate PEX-A expansion tool for the tubing end and apply thread sealant tape or compound to the NPT threads before tightening. Do not overtighten the swivel nut, as this can deform the sealing surface.
