Coilhose Pneumatics 143 Hose Coupler 1/4 in Aro Brass

Product Description

The COILHOSE PNEUMATICS 143 is a brass pneumatic hose coupler designed for use in compressed air systems requiring a reliable ARO interchange connection. Built with a 1/4 inch body diameter and a 1/4 inch inside diameter hose barb thread type, this coupler handles working pressures up to 300 psi and operates across a temperature range of -40 degrees F to 250 degrees F. It is suited for industrial, maintenance, and production environments where ARO-style quick-connect fittings are the standard. Installation is handled by pneumatic technicians and maintenance mechanics working on compressed air distribution lines and pneumatic tooling setups.

This coupler is appropriate for use in both light industrial and heavy shop environments where ARO interchange couplings are specified. The hose barb connection style allows direct attachment to compatible air hose without threading or ferrule hardware, making it a practical choice for field repairs and new installations. It is a single-piece unit, packaged individually, and is suitable for routing compressed air to pneumatic tools, actuators, and other air-powered equipment.

Key Features

• ARO interchange coupler style for broad compatibility with ARO-style pneumatic systems
• 1/4 inch body diameter with 1/4 inch inside diameter hose barb connection
• Brass construction for corrosion resistance and durability in compressed air service
• Rated to 300 psi maximum working pressure
• Wide temperature range: -40 degrees F to 250 degrees F

Compatibility

Designed as an OEM-style replacement or service fitting for compressed air systems using ARO interchange-style pneumatic couplings with hose barb connections.

Installation Notes

Installation is typically performed by a pneumatic technician or maintenance mechanic. Depressurize and bleed the air line completely before disconnecting or installing any coupler. Ensure the hose inside diameter matches the 1/4 inch barb size before seating the hose. Follow applicable shop air safety guidelines and verify all connections hold pressure before returning the system to service.
