Coilhose Pneumatics 15C90B4M 1/4 Inch Mnpt Brass Coupler

Product Description

The COILHOSE PNEUMATICS 15C90B4M is a brass pneumatic coupler designed for industrial interchange pneumatic systems. It features a 1/4 inch male NPT (MNPT) threaded connection and a 1/4 inch body diameter, making it a standard-size fitting for compressed air lines. Rated to 300 psi maximum working pressure and capable of handling temperatures from -40 degrees F to 250 degrees F, this coupler suits demanding shop and field environments. It is sold individually and installed by HVAC technicians, pipefitters, and pneumatic system mechanics working on air tool circuits and compressed air distribution lines.

This coupler is suited for industrial and commercial pneumatic applications where industrial interchange fittings are the standard. It is commonly installed on air compressor outlets, pneumatic tool connections, and compressed air distribution manifolds. The MNPT threaded connection allows direct engagement with standard NPT-tapped ports on tools, regulators, and pneumatic accessories. Its brass construction resists corrosion in typical shop environments, making it a reliable choice for both fixed installations and portable air supply setups.

Key Features

• Industrial interchange coupler style for broad compatibility with matching industrial interchange plugs
• 1/4 inch MNPT threaded connection for standard NPT port fitment
• Brass construction for corrosion resistance in compressed air service
• 300 psi maximum working pressure rating
• Wide temperature range: -40 degrees F to 250 degrees F
• 1/4 inch body diameter, compact and lightweight at 0.5 pounds

Compatibility

Designed for use with industrial interchange style pneumatic systems requiring a 1/4 inch MNPT coupler. Compatible with industrial interchange plugs conforming to the same coupling standard.

Installation Notes

Installation should be performed by a qualified pneumatic technician or pipefitter. Depressurize and bleed down the air supply line completely before removing or installing any pneumatic fitting. Apply thread sealant appropriate for compressed air service to the MNPT threads before assembly. Follow applicable OSHA and ASME B31.1 guidelines for compressed air piping and fitting installations.
