Parker MSC128HBLSV-5-4 Barbed Hose Fitting 1/4 in

Product Description

The PARKER MSC128HBLSV-5-4 is a brass barbed hose fitting configured as a female connector, designed to join a threaded port to a flexible hose in fluid transfer systems. It features a 1/4 inch NPSM female swivel ball-end thread on one side and a hose barb sized for 5/16 inch inside diameter hose on the other. The brass construction provides corrosion resistance suitable for water, hydraulic fluid, and many common fluids. The swivel ball-end design allows the fitting to rotate during installation, reducing hose twist and simplifying routing in tight spaces. Rated for service from -40 degrees F to 160 degrees F, this fitting suits a broad range of light-duty industrial and mechanical fluid line applications.

This fitting is used in plumbing, HVAC, and light industrial fluid systems where a threaded female port must transition to a barbed hose connection. It is well suited for residential and commercial service applications involving water lines, coolant circuits, and similar low-to-moderate pressure fluid transfer lines. The compact overall length of 1.5 inches makes it practical for installations with limited clearance. Licensed plumbers, HVAC technicians, and mechanical contractors are the primary installers for this type of fitting.

Installation Notes

Installation should be performed by a licensed plumber or qualified mechanical technician. Shut off and depressurize the fluid system completely before removing or installing any fitting. Hand-tighten the swivel end onto the mating port before applying a wrench to the hex head to avoid cross-threading. Confirm hose compatibility by verifying the hose inside diameter and pressure rating match the application requirements before pressurizing the system.
