Parker 179HB-12-8 Brass Elbow Barbed Hose Fitting

Product Description

The PARKER 179HB-12-8 is a brass elbow barbed hose fitting designed to connect flexible hose to threaded pipe in fluid-handling systems. It features a 1/2 inch male NPT thread on one end and a beaded hose barb sized for 3/4 inch inside diameter hose on the other. The 90-degree elbow configuration allows directional changes in tight plumbing runs without additional adapters. Rated for temperatures from -40 degrees F to 160 degrees F, this fitting suits a wide range of water, coolant, and compatible fluid transfer applications. Licensed plumbers, HVAC technicians, and mechanical contractors install this fitting in both residential and light commercial systems.

This fitting is well suited for hydronic heating lines, cooling circuits, water distribution, and equipment hookups where a hose-to-threaded-pipe transition is required at a right angle. The beaded barb design provides a secure grip on flexible rubber or PVC hose, reducing the chance of hose blowoff under normal working pressures. It is appropriate for use in mechanical rooms, equipment pads, and service panels where space is limited and a straight inline fitting is not practical.

Key Features

• Beaded hose barb provides a positive hose retention grip without clamps, though clamps are still recommended
• 1/2 inch male NPT thread connects directly to standard threaded female pipe fittings
• Sized for 3/4 inch inside diameter hose with a 0.83 inch barb diameter
• Brass construction offers corrosion resistance for water and compatible fluid service
• Wide temperature range from -40 degrees F to 160 degrees F suits HVAC and plumbing applications
• Compact elbow profile with 0.81 inch hex head allows standard wrench installation in confined spaces

Compatibility

Designed as an OEM-style replacement or new-installation fitting for systems using 3/4 inch inside diameter flexible hose terminated with 1/2 inch female NPT threaded connections.

Installation Notes

Installation is performed by licensed plumbers or qualified mechanical technicians. Shut off and depressurize the fluid system completely before disassembling any fittings. Apply thread sealant or PTFE tape to the male NPT threads per standard plumbing practice and applicable IPC requirements. Secure the hose over the barb and install an appropriate hose clamp to maintain a leak-free connection under service conditions.
