Parker 126HBL-6-4 Brass Barbed Hose Fitting 1/4 Npt

Product Description

The PARKER 126HBL-6-4 is a brass female connector barbed hose fitting designed for connecting flexible hose to threaded pipe or equipment ports. It features a 1/4 inch NPT female thread on one end and a 0.415 inch barb on the other, accepting hose with a 3/8 inch inside diameter. The brass construction provides corrosion resistance suitable for water, air, and a range of hydraulic or pneumatic fluids. Rated for service from -40 degrees F to 160 degrees F, this fitting suits both low-pressure plumbing and general-purpose fluid transfer applications. Overall length is 1.58 inches and the hex head measures 0.6875 inches across flats for standard wrench engagement.

This fitting is used in residential and light commercial plumbing, HVAC condensate and fluid lines, pneumatic tubing assemblies, and pool or irrigation systems where a flexible hose must terminate at a threaded female NPT port. It is typically installed by licensed plumbers, HVAC technicians, and irrigation professionals who need a reliable, reusable connection point between flexible hose and threaded fittings.

Installation Notes

Installation should be performed by a qualified plumber or HVAC technician following applicable IPC or local plumbing code requirements. Shut off and depressurize the system before removing or installing any fittings. Apply thread sealant tape or paste to the NPT male threads of the mating port before threading on the fitting; do not apply sealant to the barb end.
