Parker 68HB-8-MI12 Barbed Hose Fitting M12 Brass

Product Description

The PARKER 68HB-8-MI12 is a brass male connector barbed hose fitting designed to join a 1/2 inch ID hose to an M12 x 1.5 metric threaded port. The beaded hose barb design creates a secure mechanical grip on the hose, reducing the risk of blowoff under pressure or vibration. Rated for operating temperatures from -40 degrees F to 160 degrees F, this fitting suits a wide range of fluid transfer applications in HVAC, plumbing, and industrial systems. Licensed plumbers, HVAC technicians, and mechanical contractors install this type of fitting where a metric threaded connection must transition to a standard barbed hose assembly.

This fitting is suited for residential and light commercial applications where M12 x 1.5 metric threaded ports interface with 1/2 inch ID flexible hose. Typical install scenarios include equipment coolant lines, condensate lines, hydraulic pilot lines, and fluid transfer assemblies that require a compact, reliable threaded-to-barb transition. The brass construction provides corrosion resistance in wet or humid environments, making it appropriate for plumbing, hydronic, and HVAC service work.

Key Features

• Beaded hose barb design for improved hose retention and blowoff resistance
• M12 x 1.5 metric thread for direct connection to metric-threaded ports
• Accepts 1/2 inch ID hose with a 0.500 inch barb size
• Brass construction resists corrosion in wet and humid service environments
• Operating temperature range: -40 degrees F to 160 degrees F (-40 degrees C to 71.1 degrees C)
• Compact overall length of 1.5 inches with a 0.6875 inch hex head for standard wrench installation

Compatibility

Designed as an OEM-style replacement or new-installation fitting for systems requiring an M12 x 1.5 metric male thread to 1/2 inch ID hose barb connection.

Installation Notes

Installation is performed by licensed plumbers or HVAC technicians. Shut off fluid flow and relieve system pressure before removing or installing any hose fitting. Use the 0.6875 inch hex head with an appropriate open-end or combination wrench — do not over-torque brass fittings, as the material is susceptible to thread damage. Secure the hose to the barb with an appropriate clamp per system requirements and applicable codes.
