Parker 126HBL-4-2 Barbed Hose Fitting 1/4 in Id Npt

Product Description

The PARKER 126HBL-4-2 is a brass barbed hose fitting configured as a female connector, designed to transition between a 1/4-inch ID hose and a 1/8-inch female NPT threaded port. The barbed end provides a secure grip on flexible tubing, while the female NPT thread creates a leak-resistant connection to a mating male pipe thread. Rated for service from -40 degrees F to 160 degrees F, this fitting handles a broad range of fluid transfer applications. Plumbers, HVAC technicians, and mechanical contractors use this fitting in low-pressure tubing runs where a reliable hose-to-pipe-thread transition is needed.

This fitting is suited for residential and light commercial installations involving flexible hose lines in plumbing, HVAC, pneumatic, and general fluid transfer systems. The 1/8-inch NPT female thread connects directly to standard male NPT ports on valves, manifolds, equipment panels, and inline devices. The barbed end accepts 1/4-inch ID flexible hose, making it practical for short runs of vinyl or rubber tubing in tight service spaces.

Key Features

• 1/4-inch ID hose barb end grips flexible tubing securely without clamps in many low-pressure applications
• 1/8-inch female NPT thread connects to standard male NPT pipe ports
• Brass construction provides corrosion resistance for water, air, and compatible fluid service
• Operating temperature range of -40 degrees F to 160 degrees F suits a wide variety of service environments
• Compact overall length of 1.47 inches fits into confined equipment spaces
• 0.50-inch hex head allows standard wrench installation

Compatibility

Designed as a standard hose-barb-to-female-NPT connector compatible with 1/4-inch ID flexible hose and 1/8-inch male NPT threaded ports on plumbing, HVAC, pneumatic, and fluid transfer equipment.

Installation Notes

Installation is typically performed by licensed plumbers or HVAC technicians. Shut off fluid supply and depressurize the line before connecting or disconnecting any fittings. Apply thread sealant or PTFE tape to the male NPT threads per standard plumbing practice and applicable IPC or IFGC guidelines. Do not overtighten; use the hex head and a properly sized wrench to seat the fitting without cracking the fitting body.
