Fittings and Connectors
SMC’s One Touch, push to connect fittings require no tools for tube insertion, just the force of hand insertion is enough to secure its position using the holding force of the KQ’s fitting chuck and spring guide. Air or fluid leaks are prevented with an innovative anchor grip seal.
The fittings are available in inch and metric sizes, in numerous configurations and manufactured in various materials to withstand a wide range of environments from standard factory spaces to aggressive high heat welding and corrosive wash down spaces.
Specialty fittings such as: speed controls (flow controls) and couplers are also available in inch and metric sizes, in various configurations and materials.
Pneumatic tubing and for other fluids are available in inch and metric OD sizes, in various colors and materials to withstand aggressive environments.
Pneumatic Tube Fittings, One Touch Tube Fittings, Air Cylinder Speed Controls, PTFE Fittings and Tubing
SMC is your single source option for all of your pneumatic fitting, tubing, and air cylinder speed control needs.
SMC One-touch tube fittings come in metric and inch size pneumatic fittings and are available in a wide variety of sizes, body styles and thread types. The specially designed packing provides positive sealing under pressure without the reduced flow common with compression fittings. SMC offers one touch tube fittings in a number of special environments such as anti-static, flame resistant, clean room, DOT, and food service fittings.
SMC speed controllers have a broad range of applications and specialty focus such as air cylinder speed control use at low speed, and with residual pressure. Further options within the series include a built in one-touch fitting, an integrated pilot check valve, a meter-in and meter-out dual flow control, a stainless steel option. With the ASR series, the environmentally conscious consumer can reduce air consumption by 25% through the inclusion of a quick supply exhaust valve. Air cylinder speed control is easy with our comprehensive line of products.
SMC manufactures Fluoro-resin tubing for use in environments involving high temperatures and/or corrosive fluids. Pneumatic tubing is also available in a number of other materials both with and without reinforcement for use in standard applications. SMC fittings incorporate a positive tube seal while the fitting is under pressure which allows polyurethane tubing to be used.
Tubing is available in sizes of 1/8", 5/32", 3/16", 1/4", 5/16", 3/8", and 1/2". Metric tubing sizes of 3.2, 4, 6, 8, 10, 12, and 16mm are available.
Manifolds allow multiple tubes to be connected or disconnected in a one touch operation without tube connection errors. The time required for connection and disconnection is substantially reduced.
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.
Check valves block the flow of fluid in one direction while permitting flow in the other. This prevention of back flow can be an integral part of a circuit to maintain pressure, hold actuator postion or protect devices from reverse flow. Simple check valves only permit flow in one direction while pilot operated check valves can permit reverse flow when released via a pilot signal. All SMC check valves feature low cracking pressure in the normal flow direction.
