KQ2 one-touch, metric and inch size fittings are available in a wide variety of sizes, body styles and thread types. The use of a special profile seal allows the KQ2 to be used for a wide range of pressures from a low vacuum up to a pressure of 1MPa.  The KQ2 release collar releases both the chuck and collet to provide a low disconnection force for easy removal of the tubing.

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 KQG2 is more compact and lightweight, and offers more configuration variations and tube sizes than the KQG series.

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. KR fittings are effective when piping in a confined space. The body and threaded portion can turn.

Antistatic One-touch fittings series KA has one-touch loading and unloading. 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. Series KA is flame resistant (UL94 standard, V-0).

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 one-touch series KPQ/KPG (for drive system air piping) are polypropylene.

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.

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. KG 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.

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.

Compact and lightweight, the KQB2 one-touch fitting uses electroless nickel plated brass components as standard specification. Its maximum operating temperature is 150° C.  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.
