Parker MSC128HBLSV-6-6 3/8 in Barbed Hose Fitting Brass

Product Description

The PARKER MSC128HBLSV-6-6 is a brass barbed hose fitting configured as a female connector with a hose barb by female swivel ball-end design. It accepts 3/8 inch inside diameter hose and connects via a 3/8 inch NPSM female swivel thread, making it suitable for fluid transfer lines in HVAC, plumbing, and general industrial applications. The swivel ball-end design allows the fitting to rotate during installation, reducing hose twist and making routing in tight spaces more manageable. Rated for service from -40 degrees F to 160 degrees F, this fitting handles the thermal range common in light industrial and mechanical system piping work. Licensed trades and experienced installers typically specify this part for low-pressure fluid lines requiring a secure barb-to-thread transition.

This fitting is used in residential and light commercial plumbing, HVAC condensate and fluid lines, and general fluid transfer assemblies where a barbed hose end must transition to a female threaded port. The 3/8 inch hose barb accommodates standard 3/8 inch ID flexible hose, and the NPSM thread standard suits straight-thread female swivel applications. The brass construction holds up well in wet environments and resists corrosion in potable and non-potable water service. Plumbers, pipefitters, and HVAC technicians install this fitting as part of hose-to-pipe assemblies in mechanical rooms, equipment connections, and field-fabricated fluid lines.

Key Features

• Brass construction for corrosion resistance in wet and fluid-handling applications
• Female swivel ball-end allows rotation during makeup, reducing hose twist
• 3/8 inch NPSM straight thread for compatibility with standard female swivel ports
• Accepts 3/8 inch ID hose with a 0.415 inch barb for a secure mechanical grip
• Wide service temperature range: -40 degrees F to 160 degrees F
• Compact overall length of 1.5 inches suits confined installation spaces

Compatibility

Designed as a replacement or new-installation fitting for fluid transfer assemblies using 3/8 inch ID flexible hose terminated to a 3/8 inch NPSM female swivel threaded port.

Installation Notes

Installation is typically performed by licensed plumbers, pipefitters, or HVAC technicians. Shut off the fluid supply and relieve any line pressure before removing or installing hose fittings. The swivel end should be hand-tightened and then snugged with a wrench to the hex head — do not overtighten brass fittings, as this can crack the hex or distort the sealing surfaces. Ensure the hose barb is fully seated into the hose ID and secure with an appropriately sized clamp per the application requirements.
