The SMC S coupler series KK employs a unique connection method. A slim body design and large effective area are achieved with a construction that does not use steel balls or valve springs and therefore does not restrict the flow path. Together with a reduction of the body size, pressing parts and resin parts are used to achieve an overall weight reduction.

SMC S Couplers

KK Series has a unique connection method. A slim body design and large effective area are achieved with a construction that does not use steel balls and therefore does not restrict the flow path. Blocks are avoided due to no valve spring located within the flow path. This is a lightweight coupler smaller in body size.

Do not use the S couplers with a leak tester or for vacuum retention because they are not guaranteed for zero leakage
