• Operating pressure up to 150 bar when used in conjunction with a corresponding valve insert in the connecting piece.

• Approved refrigerants: HFC / HFO / PFC / CFC / HC with the exception of NH3 containing refrigerants.

For a good seal during the assembly onto a stud or connector made from the same material a suitable seal like a O-ring or cap made from copper has to be used.

Tightening torque for simple connection pieces 15-20 Nm, for connection pieces with thread for valve inserts valve inserts 7 - 10 Nm. As these connecting pieces have a slightly larger diameter, the collar of the connection piece can deform and the valve insert can then no longer be replaced.
