Parker MSC128HBLSV-8-8 Brass Barbed Hose Fitting 1/2 in

Product Description

The PARKER MSC128HBLSV-8-8 is a brass female connector barbed hose fitting designed to create a secure, leak-resistant connection between a threaded female port and a flexible hose. The fitting uses a hose barb on one end and a female swivel ball-end on the other, with a 1/2 inch NPSM thread standard. The barb accommodates hose with a 1/2 inch inside diameter. Rated for a working temperature range of -40 degrees F to 160 degrees F, this fitting is suited for fluid transfer lines in HVAC, plumbing, and light industrial applications. Licensed trade professionals and experienced installers handle this type of fitting as part of hydronic, coolant, or water-service line assemblies.

This fitting is appropriate for residential and light commercial installations where a threaded female port must transition to a flexible hose line. The swivel ball-end design allows the fitting to seat and rotate during assembly, reducing stress on the hose and mating connection. Common use scenarios include condensate lines, chilled water connections, and general fluid transfer where a barbed-to-threaded transition is required. Plumbers, HVAC technicians, and mechanical contractors regularly specify this type of connector in both new construction and service-replacement work.

Key Features

• Brass construction for corrosion resistance in fluid handling applications
• Female swivel ball-end allows rotational adjustment during tightening, reducing hose stress
• 1/2 inch NPSM thread for compatibility with standard female-threaded ports
• Barb sized at 0.53 inches for a secure grip on 1/2 inch ID hose
• Wide service temperature range: -40 degrees F to 160 degrees F
• Compact overall length of 1.52 inches suits tight installation spaces

Compatibility

Designed as an OEM-style replacement or new-installation connector for fluid transfer systems requiring a 1/2 inch NPSM female swivel to 1/2 inch ID hose barb transition.

Installation Notes

Installation is typically performed by a licensed plumber or HVAC technician. Shut off fluid supply and relieve system pressure before removing or installing any hose fitting. Hand-tighten the swivel end first, then apply a wrench to the hex head only — avoid gripping the barb or hose body. Ensure hose is fully seated past all barb ridges and secured with an appropriate clamp per local plumbing code requirements.
