Parker 125HBLSV-4-4 Barbed Hose Fitting 1/4 Inch Npt

Product Description

The PARKER 125HBLSV-4-4 is a brass barbed hose fitting in a male connector configuration, designed for fluid transfer applications in HVAC, plumbing, and industrial service. It features a hose barb on one end and a male swivel NPT thread on the other, allowing secure connection between flexible hose and threaded pipe fittings. The fitting accommodates 1/4 inch inside diameter hose and carries a 1/4 inch NPT thread. Rated for service between -40 degrees F and 160 degrees F, it suits a wide range of liquid and low-pressure gas line applications. Licensed plumbers, HVAC technicians, and mechanical contractors install this type of fitting in both new construction and service work.

This fitting is suited for residential and light commercial applications where flexible hose must transition to a threaded pipe connection. Typical install scenarios include condensate drain lines, refrigerant oil lines, water supply connections, and low-pressure fluid circuits. The male swivel NPT design allows the fitting to be threaded into a female port without rotating the connected hose, reducing installation stress on the hose assembly. The all-brass construction makes it appropriate for potable water systems, hydronic lines, and corrosion-sensitive environments.

Key Features

• Brass construction for corrosion resistance in wet and hydronic service environments
• Male swivel NPT thread eliminates hose twist during installation
• Fits 1/4 inch ID hose with a 0.29 inch barb diameter for a secure grip
• Operating temperature range of -40 degrees F to 160 degrees F
• 1/4 inch NPT thread standard for broad compatibility with threaded pipe fittings
• Compact overall length of 2.14 inches suits tight-clearance installations

Compatibility

Designed as an OEM-style replacement or new-installation fitting for systems using 1/4 inch ID flexible hose with 1/4 inch NPT threaded ports.

Installation Notes

Installation is performed by licensed plumbers or HVAC technicians following applicable IPC and IFGC guidelines. Shut off fluid supply and relieve system pressure before removing or installing any hose fitting. Apply thread sealant or PTFE tape to the NPT threads per local code requirements. Do not overtighten the swivel nut; hand-tighten and then wrench-snug to avoid cracking the brass hex.
