Parker 125HBL-8-12 Brass Barbed Hose Fitting Npt

Product Description

The PARKER 125HBL-8-12 is a brass male connector barbed hose fitting designed to join a 1/2-inch inside diameter hose to a 3/4-inch NPT male threaded port. Built from brass for corrosion resistance in fluid-handling applications, it features a hose barb end on one side and a threaded male NPT end on the other. The fitting measures 1.98 inches in overall length with a 1.0625-inch hex head, making it straightforward to install with standard hand tools. Rated for a working temperature range of -40 degrees F to 160 degrees F, it suits a broad range of HVAC, plumbing, and fluid transfer system applications.

This fitting is used wherever a flexible hose must connect to a threaded pipe or component in residential and light commercial systems. Typical install scenarios include condensate drain lines, water supply connections, fluid transfer assemblies, and HVAC equipment fittings. The barbed end grips the hose securely, while the male NPT thread engages standard pipe fittings and valves. Plumbers, HVAC technicians, and pipefitters commonly install this type of connector during new construction, equipment replacement, or system retrofits.

Installation Notes

Installation is typically performed by licensed plumbers or HVAC technicians. Shut off the water or fluid supply and relieve system pressure before installing or removing any fitting. Apply thread sealant tape or compound to the NPT threads per IPC and IFGC guidelines, and tighten to a snug, leak-free fit using an appropriately sized wrench — do not over-torque brass fittings. Secure the hose to the barb end with an appropriate clamp rated for the application pressure and temperature.
