Parker 129HB-6-6 Barbed Elbow 3/8 Hose Barb X 3/8 Male Npt

Product Description

The PARKER 129HB-6-6 is a 90-degree barbed hose fitting elbow designed to connect a 3/8-inch ID hose to a 3/8-inch male NPT threaded port. Constructed from brass, it provides reliable sealing and corrosion resistance in fluid transfer systems. The fitting features a hose barb on one end sized at 0.415 inches for secure hose retention and a male NPT threaded end for engagement with standard pipe threads. 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 pneumatic plumbing applications. Plumbers, HVAC technicians, and maintenance trades install this type of fitting in hydronic, pneumatic, and general plumbing systems.

This elbow fitting is used in residential and light commercial applications where a hose line must change direction into a threaded port. Common install scenarios include water supply connections, hydronic heating circuits, and fluid transfer lines where a 90-degree turn is needed. The NPTF thread standard provides a pressure-tight mechanical seal. The compact brass body fits in tight spaces common in equipment cabinets, boiler rooms, and mechanical chases.

Installation Notes

Installation is performed by licensed plumbers or qualified mechanical trades. Shut off fluid supply and relieve system pressure before replacing or installing any hose fitting. Apply thread sealant or PTFE tape to the male NPT threads per local plumbing code requirements before tightening. Slide the hose fully over the barb and secure with an appropriate clamp to prevent blowoff under pressure.
