Parker PP-00409 Barbed Push-on Hose Union Brass 3/4 in

Product Description

The PARKER PP-00409 is a brass barbed push-on hose union fitting designed to join two lengths of flexible hose in a straight-line configuration without the need for threaded connections or clamps. The fitting accepts 3/4 inch inside diameter hose and relies on barbed shanks on both ends to grip the hose interior and maintain a secure, low-pressure seal. Constructed from brass, it resists corrosion in wet and mildly aggressive fluid environments. This type of fitting is commonly installed by plumbers, HVAC technicians, and irrigation professionals working with flexible tubing in fluid-transfer or low-pressure line assemblies.

The PP-00409 suits residential and light commercial applications where two sections of 3/4 inch ID flexible hose must be coupled inline. Typical use cases include drain line repairs, condensate line connections, irrigation laterals, and general fluid-transfer assemblies using compatible push-on hose. The barbed push-on design allows for fast field assembly without special tooling, making it practical for service calls and retrofit work where downtime needs to be minimized.

Installation Notes

Installation is typically performed by a licensed plumber, HVAC technician, or qualified service professional. Shut off fluid flow and relieve any system pressure before disconnecting existing hose sections. Hose should be pushed fully onto the barbed shank until seated against the fitting shoulder; a hose clamp may be added for additional retention in higher-flow applications. Verify that hose material and system fluid compatibility are confirmed before installation.
