Parker PP-00408 Barbed Push-on Hose Union 5/8 in Brass

Product Description

The PARKER PP-00408 is a barbed push-on hose union fitting machined from brass, designed to join two lengths of flexible hose in a straight-line configuration. With a 5/8-inch inside diameter and a matching 5/8-inch barb size, the fitting creates a secure push-on connection without the need for threaded assembly. At 3.31 inches in length, it fits into tight plumbing, HVAC, and fluid-transfer installations. Licensed plumbers, HVAC technicians, and mechanical contractors install this type of fitting where a reliable, leak-resistant hose joint is required in low-pressure fluid or coolant lines.

This union fitting is suited for residential and light commercial applications where two sections of 5/8-inch ID flexible hose must be connected inline. Typical install scenarios include hydronic heating systems, equipment coolant circuits, condensate lines, and general-purpose fluid transfer assemblies. The brass construction makes it appropriate for water, light oils, and compatible fluid media in moderate-temperature environments.

Key Features

• 5/8-inch barb size mates with standard 5/8-inch ID push-on hose
• Brass construction provides corrosion resistance for water and fluid service
• Union design allows straight inline joining of two hose sections
• 3.31-inch overall length accommodates standard hose clamp or retention bead clearance
• Push-on barb profile grips hose securely without threaded fittings or solvents

Compatibility

Designed as an OEM-style replacement or new-installation union fitting for 5/8-inch inside diameter push-on flexible hose used in plumbing, HVAC, and fluid-transfer systems.

Installation Notes

Installation is performed by licensed plumbers or HVAC technicians following applicable IPC or local mechanical codes. Shut off and depressurize the fluid line before disassembly or fitting installation. Push hose firmly over both barbs and secure with hose clamps rated for the operating pressure of the system. Inspect hose ends for cuts or deformation before assembly to ensure a leak-free connection.
