Midland Industries 32129 Swivel Female Adapter Brass

Product Description

The MIDLAND INDUSTRIES 32129 is a brass swivel female adapter designed to connect a 1/4-inch hose barb to a 3/8-inch female NPSM gasket swivel fitting. Built from solid brass, it delivers reliable performance in low-pressure fluid transfer applications. The swivel design allows the fitting to rotate during installation, reducing hose stress and simplifying routing in tight spaces. Rated to 150 psi maximum operating pressure and suitable for service across a temperature range of -40 to 160 degrees F, this adapter handles a wide range of common fluid handling conditions. Overall length is 1.63 inches, making it a compact solution for plumbing and fluid distribution assemblies.

This fitting is well suited for residential and light commercial plumbing, irrigation, pneumatic, and fluid transfer applications where a hose barb must terminate at a female NPSM threaded connection. It is intended for use with hose clamps, similar-type clamps, or crimped ferrules to secure the hose end. Plumbers, pipefitters, and fluid system technicians routinely specify this type of adapter when connecting flexible hose runs to threaded female ports on valves, manifolds, or equipment.

Installation Notes

Installation is typically performed by a licensed plumber or pipefitter. Shut off fluid supply and relieve system pressure before servicing any fitting. Hand-tighten the swivel end onto the female NPSM port, then apply a gasket or sealing washer as required by the fitting design before final tightening. Secure the hose barb end with an appropriately sized hose clamp or crimped ferrule per system requirements and applicable plumbing codes.
