Coilhose Pneumatics 342A 3/4 Inch Mnpt Brass Coupler

Product Description

The COILHOSE PNEUMATICS 342A is a brass pneumatic hose coupler designed for Industrial Interchange pneumatic systems. It features a 3/4 inch male NPT (MNPT) threaded connection and a 3/4 inch body diameter, built to handle working pressures up to 300 psi. Rated for temperatures from -40 degrees F to 250 degrees F, this coupler suits demanding shop and field environments. Licensed HVAC technicians, plumbers, machinists, and general industrial maintenance crews install this fitting when connecting pneumatic hoses and tools on compressed air lines requiring a reliable, leak-resistant threaded coupler.

The 342A is suited for use in industrial and commercial compressed air systems where Industrial Interchange-style couplings are the standard. It is appropriate for permanent or semi-permanent hose connections in manufacturing, fabrication, and mechanical service environments. The MNPT thread allows direct installation into female-threaded ports on pneumatic tools, manifolds, or air supply lines without additional adapters when thread sizes match.

Key Features

• Brass construction for corrosion resistance and durability in compressed air service
• 3/4 inch MNPT threaded connection for direct port installation
• 300 psi maximum working pressure for standard industrial shop air systems
• Wide temperature range: -40 degrees F to 250 degrees F
• Industrial Interchange coupling type for broad compatibility across common pneumatic tooling

Compatibility

Designed as an OEM-style replacement or new-installation coupler for Industrial Interchange pneumatic systems using 3/4 inch MNPT threaded connections.

Installation Notes

This coupler is installed by mechanical technicians and industrial maintenance personnel working on compressed air systems. Depressurize the air line completely before removing or installing any pneumatic fitting. Apply appropriate thread sealant to the MNPT threads and tighten to a snug, leak-free fit using the correct size wrench. Verify the system pressure does not exceed the 300 psi rated maximum before returning the line to service.
