SMC General Purpose Fittings

SMC One-touch fittings come in metric and inch size 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 fittings in a number of special environments such as anti-static, flame resistant, clean room and food service fittings.

KQ2 Series
SMC KQ2 one-touch, metric and inch size fittings 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. The SMC KQ2 release collar releases both the chuck and collet to provide a low disconnection force for easy removal of the tubing.  SMC KQ2 fittings are available to order in multiples of 10.

KJ Series
SMC One-Touch mini fittings series KJ is available for use with SMC miniature valves and actuators, M3 and M5 ported. Their compact one-touch collet design allows easy disassembly with strong tube gripping. Electroless nickel plating is standard.  SMC KJ fittings are available to order in multiples of 10.

KQG2 Series
SMC Series KQG2 is a one-touch fitting made of all stainless steel SUS316, except seal parts. The series is suitable for use with steam and is grease-free. Applicable tubing includes FEP, PFA, nylon, soft nylon, polyurethane and polyolefin. The KQG2 series is available in both metric and inch sizes. The SMC KQG2 is more compact and lightweight, and offers more configuration variations and tube sizes than the KQG series.

KQG Series
SMC Series KQG is a one-touch fitting made of all stainless steel SUS316, except seal parts. The series is suitable for use with steam and is grease-free. Applicable tubing includes FEP, PFA, nylon, soft nylon, polyurethane and polyolefin. The SMC KQG series is available in both metric and inch sizes.

KR Series
SMC Flame resistant, one-touch fitting series KR can be used for a wide range of pressures from a low vacuum up to a pressure of 145 PSI. The use of a special profile ensures positive sealing and reduced resistance when the tube is being inserted. SMC KR fittings are effective when piping in a confined space. The body and threaded portion can turn.

KA Series
SMC Antistatic One-touch fittings series KA has one-touch loading and unloading. SMC Series KA can be used in copper- free applications and in vacuum (max. -100kPa). Conductive resin is used for body and seals in fittings and tubing. SMC Series KA is flame resistant (UL94 standard, V-0).

KP Series
SMC Series KP are one-touch fittings for clean room blow-off systems and drive air systems. The KP series is completely oil free and liquid-contact areas are non-metallic. Parts are cleaned, assembled and double packaged in a clean room. Resin parts for
SMC  one-touch series KPQ/KPG (for drive system air piping) are polypropylene.

KE Series
SMC Series KE pressure relief valve with one-touch fitting can release residual pressure from a cylinder to the atmosphere by the push button. The two types of available piping are the one-touch fitting type and the Rc(PT) screw type.

KG Series
SMC’s popular one touch technology has been incorporated into this series where all the wetted metal parts are made from stainless steel. This fitting is suitable for use in CRT production for example where the use of copper must be avoided. Other applications include wash down or other environments that could corrode normal fittings. SMC KG Series can be used for vacuum –100 kPa and pressures up to 1 MPa (~150 PSI). This fitting is available in 27 different body styles, with connection sizes from M5 to ½ R(PT), and tube sizes from 4mm OD to 12 mm OD.

KQ Series
SMC KQ uni-fit one-touch fittings only require hand tightening to assemble and a snug of the wrench to attain a positive seal in 1/3 of the time of conventional fittings. The innovative design allows use of uni-fit one-touch fittings with NPT, NPTF, RC(PT), and G(PF) threads making the uni-fit design both versatile and time saving. SMC KQ fittings give you identical heights when used in manifolds or other side by side applications enhancing the appearance of your equipment.  SMC KQ fittings are available to order in multiples of 10.

KC Series
SMC self-seal fitting series KC is best for multiple use areas when pressure cannot be shut down. One- touch fittings (with built-in self-seal mechanism) are used to prevent air exhaust when removing tube. There are 10 styles available including electroless nickel plated for copper-free applications.

KQB2 Series
Compact and lightweight, the SMC KQB2 one-touch fitting uses electroless nickel plated brass components as standard specification. Its maximum operating temperature is 150° C.  SMC KQB2 fittings can be used with fluid, and in environments having a large temperature change.  Configuration variations have been improved to 17 models.  Applicable tube sizes are Ø3.2 to Ø16 and 1/8" to 1/2".  Series KQB2 is available with M, R, Rc, UNF, NPT or G connection threads.

KE Series
The SMC KQB series uses brass for metal and special FKM for rubber.  It's maximum operating temperature is 150° C.  SMC KQB fittings can be used with fluid and in environments having a large temperature change.  The available shapes to this fitting are male connector, elbow union, elbow, male branch tee, tee, hexagon socket head male connector, union "Y", straight, and bulkhead union.  Applicable tube O.D. are ø4, ø6, ø8, ø10, and ø12.  Also, available connection sizes are M5, R1/8, R1/4, R3/8, R1/2, and no thread.
