Pneumatic Quick Connect Couplings

The SMC KKA series has 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. It is non-greased. Seal material FKM Fluid is water, air

Female thread. Body size: 1/8, 1/4, 1/2, 3/4, 1, 1 1/4. Applicable Port Size: Rc1/8, Rc1/4, Rc3/8, Rc1/2, Rc3/4, Rc1, Rc1 1/4, Rc1 1/2. For these non-cancellable (NC), and non-returnable (NR) products, Terms and Conditions apply.

KK4 Series The SMC coupler, male thread is a versatile and efficient connector, perfect for various pneumatic applications. With a slim body design and a unique connection method, this coupler provides a large effective area without restricting the flow path. It offers a sleeve lock mechanism and is designed for air and water fluids. Unique connection method for efficient performance Slim body design with a large effective area No steel balls or valve springs used, allowing for a smooth flow path Reduction in body size and overall weight for easy handling Sleeve lock mechanism for secure connections Ideal for general purpose applications with its effective area of 3.8 to 82mm Suitable for air and water fluids 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. Note Do not use the S couplers with a leak tester or for vacuum retention because they are not guaranteed for zero leakage

KK4 Series 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.
