Watts Brass Tubular PL-3027 Quick Connect Adapter

Product Description

The WATTS BRASS TUBULAR PL-3027 is a quick connect tube-to-male pipe thread adapter designed for use in potable water and plumbing distribution systems. It accepts 3/8 inch O.D. tubing on the quick connect end and transitions to a 1/2 inch male pipe thread (MPT) on the other end. The push-to-connect fitting eliminates the need for compression rings or ferrules, speeding up installation in tight spaces. This adapter is rated for use with poly or soft copper tubing only. It is not approved for use with steel tubing or in any concealed installation.

This fitting is commonly used in residential and light commercial plumbing applications where a quick, tool-free connection is needed between flexible supply tubing and a threaded port. Typical install scenarios include under-sink water supply runs, refrigerator ice maker lines, reverse osmosis system connections, and other accessible tubing runs where poly or soft copper is the specified material. Licensed plumbers and experienced service technicians are the primary installers of this fitting type.
