Coilhose Pneumatics 152A 1/4 Inch Mnpt Brass Coupler

Product Description

The COILHOSE PNEUMATICS 152A is a brass pneumatic hose coupler designed for industrial compressed air systems. It features a 1/4 inch male NPT (MNPT) threaded connection and a 1/4 inch body diameter, conforming to the Industrial Interchange standard for broad compatibility across pneumatic tool setups. Rated to 300 psi maximum working pressure, this coupler handles the demands of shop air lines, production floors, and service bays. It operates across a wide temperature range, from -40 degrees F to 250 degrees F. Licensed plumbers, pipefitters, and industrial maintenance technicians install this type of fitting in compressed air distribution networks and portable air tool applications.

The 152A suits residential garage workshops, commercial auto service shops, and light industrial facilities where Industrial Interchange fittings are the facility standard. Its threaded brass construction makes it a reliable choice for permanent or semi-permanent air line installations where corrosion resistance and pressure integrity are required. The MNPT thread connects directly to air hose ends, manifolds, regulators, filters, and tool inlets carrying standard NPT threading.

Key Features

• Industrial Interchange standard for wide cross-brand coupler and plug compatibility
• 300 psi maximum working pressure for typical shop air service
• Operating temperature range: -40 degrees F to 250 degrees F
• 1/4 inch MNPT threaded connection for direct NPT fitting attachment
• Brass construction provides corrosion resistance in compressed air environments
• 1/4 inch body diameter matches standard quarter-inch pneumatic line sizing

Compatibility

Designed as an OEM-style replacement or upgrade coupler for pneumatic systems using the Industrial Interchange standard with 1/4 inch NPT threaded connections.

Installation Notes

Installation is performed by a qualified technician or pipefitter. Depressurize and bleed the air line completely before removing any existing fitting or coupler. Apply thread sealant tape or liquid thread sealant rated for compressed air to the MNPT threads before installation to ensure a leak-free connection. Verify that the downstream system pressure does not exceed the 300 psi rated working pressure of this coupler.
