Coilhose Pneumatics 145 Pneumatic Hose Coupler Aro Brass

Product Description

The COILHOSE PNEUMATICS 145 is a brass pneumatic hose coupler designed for use in compressed air systems where a reliable, leak-free connection is required. It features a 1/4 inch body diameter with a 3/8 inch male NPT (MNPT) threaded connection. 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 pneumatic setups. The ARO interchange design ensures broad tool and hose compatibility. Licensed HVAC techs, plumbers, and general trade pros commonly use this coupler to connect air hoses to compressors, manifolds, and pneumatic tools.

This coupler is suited for residential and light commercial trade applications where ARO-style quick-connect fittings are standard. Typical install scenarios include air compressor outlet connections, pneumatic tool lines, and portable compressor setups on job sites. The 3/8 inch MNPT thread makes it compatible with standard NPT-ported air equipment. The brass construction holds up well in both indoor shop environments and outdoor service conditions across a wide temperature range.
