Watts Brass Tubular PL-3016 Quick Connect Coupling

Product Description

The WATTS BRASS TUBULAR PL-3016 is a quick connect coupling designed to join 5/16 inch OD tubing to 1/4 inch OD tubing in refrigerator water supply lines. This lead-free fitting provides a secure, tool-optional connection between two common tubing sizes used in appliance water delivery systems. It is compatible with polyethylene tubing and reinforced vinyl tubing, making it a practical solution for technicians who need a reliable transition coupling during installation or service. Each package contains 5 units, sold by the each (EA) for flexible ordering. Plumbing and appliance service professionals are the primary installers of this fitting.

This coupling is intended for use with LG refrigerators, specifically where a water supply line transitions between 5/16 inch OD and 1/4 inch OD tubing. It is commonly installed during appliance hookups in residential kitchens where the incoming supply line does not match the refrigerator inlet tubing diameter. The lead-free construction meets material safety requirements for potable water contact applications. The quick connect design reduces installation time and minimizes the need for compression fittings or additional adapters in tight appliance spaces.

Installation Notes

Installation is typically performed by a plumber or qualified appliance service technician. Before installing, shut off the water supply to the refrigerator line and relieve any residual pressure. Ensure tubing ends are cut cleanly and squarely before inserting into the quick connect fitting to achieve a proper seal. Follow applicable local plumbing codes and the appliance manufacturer guidelines for water line connections.
