Parker 1695HB-6-4 Brass Barbed Hose Elbow 3/8 in Id

Product Description

The PARKER 1695HB-6-4 is a brass elbow barbed hose fitting designed to connect 3/8-inch inside diameter hose to a 7/16-20 SAE straight thread port. The beaded hose barb design provides a secure grip on the hose, reducing the risk of pull-off under pressure or vibration. Constructed from brass, this fitting resists corrosion and handles a wide temperature range from -40 degrees F to 160 degrees F, making it suited for hydraulic, pneumatic, fuel, and fluid transfer lines in HVAC, plumbing, and general industrial applications. Licensed technicians and tradespeople working on refrigerant, oil, or water lines will find this a reliable OEM-style connection component.

This fitting is commonly installed in residential and light commercial systems wherever a hose-to-threaded-port elbow transition is required. The 7/16-20 SAE straight thread end mates with standard SAE ports, while the 3/8-inch barb accepts flexible hose in fuel, coolant, and low-pressure hydraulic circuits. The 90-degree elbow configuration is useful in tight spaces where a straight fitting would create routing or clearance issues.

Key Features

• Beaded hose barb provides added retention and resistance to hose pull-off
• Brass construction offers corrosion resistance in fluid and fuel service
• 7/16-20 SAE straight thread end for secure, leak-resistant port connections
• 90-degree elbow geometry simplifies routing in confined installations
• Rated from -40 degrees F to 160 degrees F for broad application compatibility
• Hex head size of 0.5625 inches allows standard wrench installation without special tooling

Compatibility

Designed as an OEM-style replacement or new-installation fitting for systems requiring a 3/8-inch ID hose barb to 7/16-20 SAE straight thread elbow connection in brass.

Installation Notes

Installation is performed by qualified plumbers, HVAC technicians, or hydraulic system technicians. Always depressurize and drain the line before removing or installing any hose fitting. Thread the SAE straight thread end into the port by hand first to avoid cross-threading, then tighten with an appropriately sized wrench to the fitting hex. Secure the hose to the barb with an approved clamp appropriate to the application pressure and fluid type.
