Parker PP-00411 Barbed Push-on Hose Union Brass 1 in

Product Description

The PARKER PP-00411 is a brass barbed push-on hose union fitting designed to join two lengths of flexible hose in a straight-line configuration. It uses a barbed connection style that grips the inner wall of the hose when pushed on, creating a secure mechanical connection without the need for threaded ends or additional fittings. With a 1-inch inside diameter, this union is sized for medium-bore hose lines and is machined from brass for corrosion resistance and durability in fluid-handling applications. Plumbers, HVAC technicians, and irrigation or fluid transfer specialists are the typical installers.

This fitting suits residential and light commercial fluid transfer systems where flexible hose is routed between components, equipment, or supply lines. Common applications include water supply connections, low-pressure hydraulic lines, coolant circuits, and general-purpose liquid transfer. The push-on barb design makes it well suited for shop air lines, garden and irrigation hose assemblies, and service equipment fluid routing where a quick, tool-minimal connection is preferred.

Installation Notes

Installation is performed by plumbers, HVAC technicians, or qualified service technicians. Before servicing any hose line, shut off and depressurize the system and drain residual fluid from the line. Slide hose clamps onto each hose section before pushing the hose ends fully onto the barbed fittings, then position and tighten the clamps over the barb seats. Verify the hose is fully seated past the barbs and inspect for leaks after restoring system pressure.
