Parker 685HB-10-8 Barbed Hose Fitting Male Connector

Product Description

The PARKER 685HB-10-8 is a brass male connector barbed hose fitting designed for secure, leak-resistant hose-to-port connections in fluid-handling systems. It features a 3/4-16 SAE straight thread on one end and a 5/8-inch ID beaded hose barb on the other. The beaded barb profile improves hose retention under pressure and vibration. Rated for service from -40 degrees F to 160 degrees F, this fitting suits a wide range of hydraulic, pneumatic, and general fluid-transfer applications. Licensed tradespeople and equipment technicians working on fluid circuits install this type of fitting as part of standard hose assembly and routing work.

This fitting is appropriate for residential and light commercial fluid-system plumbing where a threaded port connection to a 5/8-inch ID hose is required. Typical applications include HVAC equipment, hydraulic hose assemblies, coolant circuits, and general industrial fluid routing. The SAE straight thread end mates with a corresponding straight-thread port, providing a more reliable seal than tapered pipe threads in dynamic or vibration-prone environments. Installation is suited to environments requiring compact, reliable hose terminations in tight spaces.

Key Features

• Beaded hose barb on 5/8-inch ID end improves hose grip and pull-off resistance
• 3/4-16 SAE straight thread provides a consistent, leak-resistant port connection
• Brass construction offers corrosion resistance in fluid and coolant service
• Wide temperature range: -40 degrees F to 160 degrees F
• Compact overall length of 1.56 inches suits tight installation spaces
• Hex head size of 0.875 inches allows standard wrench installation

Compatibility

Designed as an OEM-style replacement or new-installation fitting for fluid-handling systems requiring a 5/8-inch ID hose barb with a 3/4-16 SAE straight thread male connector end.

Installation Notes

Installation should be performed by a qualified technician familiar with fluid-system hose assemblies. De-pressurize and drain the system before removing or installing any fittings. Apply an appropriate thread sealant or O-ring to the straight thread port connection as required by system specifications and applicable plumbing codes. Do not overtighten; use the hex head with a properly sized wrench and follow the system manufacturer's torque guidance for the port material.
