SharkBite 1/4 in DZR Brass Coupling

This SharkBite U004LF coupling connects copper, PEX and CPVC tubing in any combination without soldering, unions or glue. The push-fit design suits residential and light-commercial plumbing repairs where speed and tool-free installation matter. It is listed to ANSI/NSF-61, ASSE 1061, NSF 103, IAPMO and IGC 188 for potable-water use.

Deciding Specification: 1/4 in Tube Size

The fitting accepts only 1/4 in outside-diameter tubing, so it will not join larger supply lines such as 1/2 in or 3/4 in pipe. Installers working on standard fixture supplies must select a different size coupling. Verify the tubing diameter before ordering to avoid mismatched connections.

What the Push-Fit Design Changes

The integral EPDM gasket and stainless-steel grip ring create a watertight seal the moment the tube is pushed home, eliminating the need for flux, solder, crimp tools or solvent cement. This reduces installation time and allows immediate pressure testing up to 200 psi across a temperature range of 0 to 200 °F. The coupling carries California Proposition 65 warnings for listed chemicals.
