Parker Push-Fit Union Fitting 1/2 in

This Parker 6316 push-fit union fitting joins two 1/2 inch tubes using a tool-free push-to-connect design on both ends. The body is moulded from white bio-based nylon and rated for 230 psi at up to 200 degrees Fahrenheit. It measures 2 1/4 inches in overall length and ships without pre-applied thread sealant.

Replacing Compression or Barbed Unions

The push-to-connect mechanism removes the need for wrenches, ferrules or clamps when joining 1/2 inch tubing in vacuum or pressure lines. The upgrade is worthwhile when faster assembly, easier disassembly for maintenance, or a lighter-weight nylon fitting is preferred over metal compression or barbed alternatives.

Installers Needing Quick 1/2 Inch Tube Connections

Plumbers, maintenance technicians and OEM assemblers who work with 1/2 inch tubing in water, air or vacuum systems will benefit from the tool-free installation and bio-based nylon construction. Buyers requiring metal fittings, higher temperature ratings, different tube sizes or integrated thread sealant should consider other fitting types.

Questions about this item

What tube outer diameter must the pipe have for the Parker 6316 push-fit union fitting?

The fitting accepts 1/2 in outer-diameter tube on both ends, so the pipe must match that size for a secure push-to-connect seal.

What is the installation step people often miss when connecting the Parker 6316 union?

Push each tube fully into the fitting until it bottoms out; a partial insert will not engage the internal collet and can leak under pressure.

When should the Parker 6316 bio-based nylon union be replaced in a hot-water line?

Replace it if the fitting sees temperatures above 200 °F or pressures above 230 psi, or if the white nylon body shows cracking or discoloration.
