Parker 179HB-12-MI18 Barbed Hose Elbow 3/4 in Brass

Product Description

The PARKER 179HB-12-MI18 is a brass elbow barbed hose fitting designed to connect 3/4-inch inside diameter hose to an M18 x 1.5 metric threaded port. The elbow configuration allows a directional change in the hose run, reducing stress on the hose and fitting at tight routing points. Constructed from brass, this fitting offers solid corrosion resistance in fluid transfer applications. The beaded hose barb design provides a secure grip on the hose, minimizing the risk of blowoff under pressure. It is rated for service from -40 degrees F to 160 degrees F, making it suitable for a wide range of liquid and low-pressure fluid systems encountered in HVAC, plumbing, and industrial service work.

This fitting is used in applications where a 3/4-inch ID hose must terminate at a metric M18 x 1.5 threaded connection at an angle. Typical install scenarios include coolant lines, fluid transfer assemblies, and equipment plumbing where a straight fitting would create excessive hose bend or strain. The threaded end engages an M18 x 1.5 metric port directly, making it a practical solution for equipment with metric-threaded fittings. Plumbers, HVAC technicians, and industrial maintenance professionals commonly specify this type of fitting for both OEM replacements and custom fluid routing work.

Key Features

• Elbow configuration redirects hose routing to reduce strain on hose and connected components
• Beaded hose barb design improves hose retention and resists pulloff
• Brass construction provides corrosion resistance for fluid transfer service
• M18 x 1.5 metric thread mates directly to metric-ported equipment
• Wide service temperature range: -40 degrees F to 160 degrees F
• 3/4-inch ID hose barb accommodates standard 3/4-inch hose

Compatibility

Designed for use with 3/4-inch inside diameter hose and equipment fitted with M18 x 1.5 metric threaded ports in fluid transfer, coolant, and low-pressure plumbing applications.

Installation Notes

This fitting is typically installed by licensed plumbers or qualified HVAC or industrial maintenance technicians. Shut off fluid flow and depressurize the system before installation. Ensure the metric thread is clean and undamaged before engagement, and apply thread sealant appropriate for the fluid media and operating temperature. Secure hose to the barb with an appropriate clamp rated for the system pressure and hose size.
