Parker 129HB-12-12 Barbed Elbow 3/4 Hose Barb X 3/4 Male Npt

Product Description

The PARKER 129HB-12-12 is a brass barbed hose fitting in a 90-degree elbow configuration, connecting a 3/4-inch ID hose barb to a 3/4-inch male NPTF threaded port. The barb end features a 0.79-inch barb diameter sized to grip 3/4-inch ID flexible hose, while the threaded end conforms to NPTF standards for a pressure-sealing connection without additional sealant on compatible fittings. The brass construction provides corrosion resistance suitable for water, air, and many fluid transfer applications. This fitting is installed by plumbers, HVAC technicians, and industrial maintenance personnel in systems requiring a directional change in hose routing at a threaded port.

This elbow fitting is used in residential and light commercial plumbing, HVAC condensate and water supply lines, pool and spa equipment plumbing, and general fluid transfer systems where a 3/4-inch flexible hose must connect to a 3/4-inch male NPT port at a 90-degree angle. It is suited for systems operating within a temperature range of -40 degrees F to 160 degrees F, making it appropriate for hot and cold water service as well as low-pressure air lines.

Installation Notes

Installation should be performed by a licensed plumber or qualified technician in accordance with applicable IPC or local plumbing code requirements. Shut off the water supply and depressurize the line before making or breaking any connections. Secure the hose barb connection with an appropriate hose clamp rated for the system pressure and fluid type. Apply thread sealant or PTFE tape to the male NPTF threads as required by the mating fitting and system fluid compatibility.
