The multi-coupling PSF4 with four ISO 10 flat face couplings is available with different types of threads for pipes according to the customer’s needs. DNP says the couplings are also perfectly interchangeable with the competitors’ ones and, in this way, they can be easily installed on the multi-couplings of other producers too. The male couplings have a standard integrated decompression system, which allows the two semi-multi-couplings to be connected even with residual pressure on the male side.
