Watts Brass Tubular PL-3020 Quick Connect Union 3/8 Inch Od

Product Description

The WATTS BRASS TUBULAR PL-3020 is a quick connect union fitting designed to join two lengths of 3/8 inch OD tubing without tools or compression fittings. It accepts poly tubing and soft copper tubing, making it a practical choice for water supply, filtration, and low-pressure fluid transfer lines. The push-to-connect design allows fast, repeatable connections in tight spaces where wrench access is limited. Plumbers and water treatment technicians working on residential and light commercial systems will find this fitting suited to situations where speed of assembly matters. It is sold in a pack of 5 units and weighs 0.25 pounds per pack.

This fitting is intended for exposed or accessible plumbing runs using poly or soft copper tubing. It is not rated for use with steel tubing and must not be installed in concealed locations such as inside walls, ceilings, or floors. Typical applications include under-sink water filtration systems, reverse osmosis supply lines, ice maker supply connections, and similar accessible service points where tubing can be inspected and serviced.
