Fittings
Festo Fittings form the basis for pipe-and-tube compressed air installation. The range divides into barbed fittings (ACK, CK, C) for tube ends with external ridges, threaded fittings (blanking plugs B, double nipples ESK, elbows G, distributors FR) for all common pipe and thread connections, tool-free push-in fittings (QS, NPQH, QSK, QSR, QS-V0, CRQS), and click fittings for particularly fast assembly and disassembly.
