One Touch Tube Fittings

General Purpose Tube Fittings

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

Specialty Pneumatic Fittings

Specially designed one touch fittings are available for use in demanding pneumatic application environments. Fluoropolymer fittings are available for use in clean room environments and swivel fittings can be used for rotary applications. Spark resistant fittings are appropriate for use in welding operations.

Stainless Steel and Brass Fittings

The SMC brass fittings and stainless steel one touch fitting series are compact and lightweight. These two options offer even more configuration variations of one touch fitting designs and tube sizes than the earlier KQG series. These brass and stainless steel fittings are versatile working with the following tubing: FEP, PFA, nylon, soft nylon, polyurethane, and polyolefin.

Manifolds

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.

Controllers

Air Cylinder Speed Control

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.

Tubing Designed for Use with SMC One Touch Fittings

Tubing

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.

Tubing Series:
Polyurethane Tubing: TAU, TCU, TFU, TIUB, TU
Nylon Tubing: T, TAS, TIA, TISA, TRS, TS
Spark Resistant Tubing: TRB, TRTU
Coaxial Tubing: TW
Polyolefin Tubing: TP
Moisture Control Tubing: IDK

High Purity Fittings and Tubing

High Purity PTFE Tubing

Utilizing high grade, high purity fluoropolymer for its extrusion (see SMC for details) SMC's TIL Series tubing meets the most stringent industry standards for cleanliness, including SEMI F57. The internal surface finish and overall manufacturing quality set the standard.

High Purity Fittings

SMC's flagship fluoropolymer fitting, Series LQ3 is now the default standard at the world's largest semiconductor OEM and end user customers. The robust, leak-free mechanical structure and high purity swept flow characteristics make LQ3 the new industry standard in critical fluid management. LQ3 is suitable for a wide range of applications including semiconductor, automotive, genetic engineering, textile, hydrogen fuel cells, and many others.
