Brass A/C hose adapter coupler

The AirSept 72151 is a brass fitting designed for R1234yf automotive air-conditioning service. It connects a 1/4 inch hose to a 1 inch outside-diameter port on the vehicle system. Professional technicians and DIY mechanics use it during refrigerant recovery, evacuation or recharge procedures.

Steel body with brass finish

The coupler uses a steel body with a brass finish to resist corrosion from refrigerant and lubricants. Its 1 inch by 1-1/2 inch profile fits standard service ports without excessive force. The single-piece construction minimises leak paths during normal operation.

Questions about this item

How is the AirSept 72151 brass coupler installed on a 1/4 in. hose for R1234yf service?

Thread the 1/4 in. adapter fitting onto the hose end, then tighten the 1 in. outside-diameter brass body to the service port; the step often missed is fully seating the coupler before pressurising the system.

What maintenance or replacement will the AirSept 72151 coupler need after repeated R1234yf use?

Inspect the brass threads and internal seal for wear or corrosion each season; replace the coupler if the 1/4 in. fitting no longer seals or the 1 in. body shows deformation.
