Value Collection PC56GW-53 Union Tube Fitting 5/16x3/16

Product Description

The VALUE COLLECTION PC56GW-53 is a push-to-connect union tube fitting designed to join two lengths of tubing in a straight-line configuration without tools. Molded from polyoxymethylene (POM), a rigid acetal-based thermoplastic known for chemical resistance and dimensional stability, this fitting handles working pressures up to 150 psi. It accepts tubing with outside diameters of 5/16 inches on one end and 3/16 inches on the other, making it a reducing union for joining two different tubing sizes. Plumbers, HVAC technicians, and fluid-handling technicians install this type of fitting in low-pressure pneumatic, water, or fluid-transfer line applications.

This fitting is suited for residential and light commercial installations where a quick, reliable tube connection is needed without soldering, threading, or compression tools. Typical applications include condensate drain lines, pneumatic control tubing, water purification systems, and other low-pressure fluid-handling assemblies where POM material is compatible with the process fluid. The push-to-connect mechanism allows fast field assembly and straightforward disconnection for servicing.

Key Features

• Push-to-connect design allows tool-free installation and removal
• Reducing union configuration joins 5/16 inch OD tubing to 3/16 inch OD tubing
• POM (polyoxymethylene) construction provides chemical resistance and dimensional stability
• Rated to 150 psi working pressure
• Compact design suited for tight routing in equipment cabinets and panels

Compatibility

Designed as an OEM-style replacement or service fitting for low-pressure pneumatic and fluid-handling tubing systems using 5/16 inch and 3/16 inch OD tubing.

Installation Notes

Installation is performed by plumbers, HVAC technicians, or qualified fluid-system technicians. Before installing or removing this fitting, shut off all pressure to the tubing circuit and verify the line is fully depressurized. Ensure cut tubing ends are clean, square, and free of burrs before insertion to achieve a proper seal. Confirm that the process fluid is compatible with POM material prior to installation.
