Parker 68HB-10-8 Barbed Hose Fitting 1/2 Npt X 5/8 Id Brass

Product Description

The PARKER 68HB-10-8 is a brass male connector hose barb fitting designed to create a secure, leak-resistant joint between a 1/2 inch NPT male thread and a 5/8 inch ID hose. The fitting features a beaded hose barb profile, which bites into the hose wall for positive retention without additional clamps in low-pressure applications, though clamps are still recommended for reliability. Constructed entirely from brass, it resists corrosion in water, air, and many fluid-transfer applications. Rated for service from -40 degrees F to 160 degrees F, this fitting suits a wide range of HVAC, plumbing, and general fluid-handling installations.

This fitting is commonly used in residential and light commercial HVAC condensate drain lines, equipment cooling circuits, water supply connections, and compressed-air or pneumatic hose assemblies where a threaded port must transition to a flexible hose. The 1/2 inch NPT thread mates directly to standard NPT-tapped ports on pumps, valves, and equipment manifolds. The 5/8 inch ID barb accepts standard flexible hose of matching inside diameter. Licensed plumbers, HVAC technicians, and pipefitters typically install this fitting in new construction and service work.

Installation Notes

Installation should be performed by a licensed plumber or qualified HVAC technician in accordance with applicable IPC or IFGC requirements. Shut off fluid supply and relieve system pressure before removing or installing any fitting. Apply thread sealant tape or pipe compound to the NPT male threads before assembly and tighten with a wrench to the hex flats — do not over-tighten or use the hose barb as a grip point. Secure the hose to the barb with an appropriately rated hose clamp when the application involves pressure or vibration.
