Coilhose Pneumatics 151A Pneumatic Hose Coupler Brass

Product Description

The COILHOSE PNEUMATICS 151A is a brass pneumatic hose coupler designed for industrial compressed air and pneumatic tool applications. It features a 3/8 inch FNPT threaded connection and a 1/4 inch body diameter, making it a compact, durable fitting for connecting air hoses to tools, regulators, and manifolds. Rated for a maximum working pressure of 300 psi and a temperature range of -40 to 250 degrees F, this coupler handles the demands of typical shop and field pneumatic systems. It is installed by HVAC technicians, plumbers, mechanics, and general contractors working with compressed air equipment.

This coupler is suited for residential and commercial pneumatic systems using the Industrial Interchange standard, one of the most widely adopted quick-connect formats in North American trade work. It threads directly into air tools, hose fittings, and pneumatic control components that accept a 3/8 inch FNPT female port. The brass body resists corrosion and holds up well in moderate-duty shop environments where air lines are connected and disconnected regularly.

Key Features

• Industrial Interchange coupler format for broad tool and hose compatibility
• Brass body construction for corrosion resistance and durability
• 3/8 inch FNPT threaded connection for secure, leak-resistant installation
• 1/4 inch body diameter suits standard lightweight pneumatic fittings
• Rated to 300 psi maximum working pressure
• Operable from -40 to 250 degrees F for year-round shop and field use

Compatibility

Designed as an OEM-style replacement or addition for pneumatic systems using the Industrial Interchange coupler standard with 3/8 inch FNPT threaded ports.

Installation Notes

Installation is typically performed by qualified pneumatic or mechanical service technicians. Depressurize the air line completely before removing or installing any coupler. Apply thread sealant tape to the FNPT threads to ensure a leak-free connection and torque by hand until snug, then tighten with a wrench. Inspect the coupler and mating plug for wear or damage before returning the system to service.
