SMC Push-in Fittings, Tubing and Flow Controls

Connecting and controlling compressed air lines

This category brings together the SMC components that keep the air supply between valve manifold, FRL unit and cylinder leak-free and easy to adjust. The range covers straight push-in fittings and male elbows, tees – including reducing versions – and S couplers for quickly disconnecting lines. It is complemented by polyurethane and FEP tubing, speed controllers and flow control valves, pressure regulators and blow-off equipment such as air blow guns, nozzles and copper pipe nozzle kits.

Versions and selection criteria

• Push-in fittings: the shape (straight, elbow, tee), port thread and tube outside diameter must match both the component and the tubing.
• Tubing: polyurethane tubing is flexible and versatile, while FEP tubing is used where higher chemical or thermal resistance is required. Coiled tubing provides a flexible supply to moving tools, and different colours make it easier to identify lines.
• Speed controllers: for setting piston speed, available as single or dual versions, with push-in connections or with a pilot valve.
• Regulating valves: pressure and flow control valves to match each consumer; air saving valves help reduce air consumption.
• Blow-off equipment: blow guns and nozzles for cleaning, drying and blowing out.

SMC connection technology at KSK Components

At KSK Components you source SMC fittings and tubing together with valves, cylinders and other industrial components from well-known manufacturers in one place. This simplifies reordering for maintenance as well as putting together the material for new machines. Registered business customers see their individual customer group prices after logging in.

Frequently asked questions

Which tube fits a push-in fitting?

The tube outside diameter is decisive: it must match the nominal size of the push-in port. Also make sure the tube is cut cleanly and squarely so that the connection seals properly.

Where is a speed controller installed?

Usually directly at the cylinder port. In most cases the exhaust air is throttled so that the piston moves smoothly; the check function lets air flow freely in the opposite direction.

When is FEP tubing the better choice?

Polyurethane tubing is the flexible standard solution for compressed air. FEP tubing is chosen when higher resistance to media or temperature is required – check suitability against the manufacturer's specifications.
