Midland Industries 32957 Rigid Male Adapter Brass Fitting

Product Description

The MIDLAND INDUSTRIES 32957 is a rigid male adapter fitting machined from brass, designed to connect a 7/16-inch hose barb to a 3/8-inch male NPTF threaded port. The barb end accepts standard flexible hose secured with a hose clamp, similar-style clamp, or a crimped ferrule. The NPTF thread measures 3/8-18 and provides a pressure-tight seal without the need for additional sealant tape in many applications. The fitting measures 1.73 inches in length with a 0.7-inch hex for wrench engagement, and it handles operating pressures up to 150 psi across a temperature range of -40 to 160 degrees F.

This adapter is suited for plumbing, HVAC, and fluid-transfer applications where a flexible hose must transition to a rigid threaded male NPTF port. It is commonly installed in residential and light commercial systems involving water, fuel lines, pneumatic circuits, or similar fluid media within its rated pressure and temperature limits. The brass construction resists corrosion and performs reliably in both wet and dry environments. Licensed plumbers and HVAC technicians typically install this fitting during rough-in or service work.

Key Features

• 7/16-inch hose barb end accepts flexible hose with clamp or crimped ferrule retention
• 3/8-18 NPTF male thread for pressure-tight connection at the port end
• Rated to 150 psi maximum operating pressure
• Temperature range of -40 to 160 degrees F
• 0.7-inch hex flat for standard wrench installation
• Brass construction provides corrosion resistance for fluid-transfer service

Compatibility

Designed as an OEM-style brass hose barb adapter for systems requiring a 7/16-inch barb to 3/8-inch male NPTF connection secured with a hose clamp, similar-type clamp, or crimped ferrule.

Installation Notes

Installation is typically performed by a licensed plumber or HVAC technician. Shut off all system pressure and drain the line before removing or installing any fitting. Use an appropriately sized open-end or adjustable wrench on the hex flat to avoid distorting the fitting body. Verify that the mating NPTF port and hose clamp torque comply with applicable IPC or IFGC requirements for the fluid being handled.
