Parker B34-6B Hose Barb Pneumatic Coupler 3/8 in Brass

Product Description

The PARKER B34-6B is a hose barb industrial pneumatic coupler designed to create secure, reliable connections in compressed air and pneumatic systems. Built from brass, this coupler features a 3/8 inch body diameter and accepts a 1/2 inch hose ID. The barb design grips the hose interior to resist pullout under pressure, making it a dependable choice for pneumatic tool lines, air compressor drops, and shop plumbing. It is installed by HVAC technicians, industrial maintenance mechanics, and plumbing professionals working with compressed air distribution systems.

This coupler is suited for residential and light commercial pneumatic applications where a hose barb fitting is required to transition from rigid pipe or fittings to flexible pneumatic hose. The 3/8 inch body size is a common standard in shop air lines and pneumatic tool circuits. It is typically used where quick, solid hose connections are made to air tools, blow guns, or pneumatic actuators.
