Pneumatic Fitting for Compressed Air Lines, Valves and Cylinders
Compressed air is expensive to make, and leaks waste it every second. A worn or wrong fitting hisses air away, lowers line pressure and slows machines down. A good pneumatic fitting connects tubing to valves, cylinders and air tools quickly and seals tightly. At Wisdo Merchants, we supply pneumatic fittings to factories, packaging lines, workshops and maintenance teams across Nairobi and Kenya.
In a compressed air system, fittings join every section together, from the compressor to the last cylinder. Push-in fittings make this fast. You simply push the tube in, and an internal collet grips it while an O-ring seals around it. To release the tube, you press the collar and pull it out. As a result, technicians can build or change air lines in minutes without special tools.
Features and Benefits of the Pneumatic Fitting
- Fast push-in connection. Push the tube in to connect, and press the collar to release it.
- Leak-free seal. An internal O-ring seals tightly around the tube.
- Secure grip. A collet holds the tube firmly under pressure.
- No special tools. Connect and disconnect by hand in seconds.
- Versatile shapes. Straight, elbow and tee fittings route air lines neatly around machines.
For maintenance teams, this means quicker repairs and fewer air leaks. Meanwhile, owners save on compressor power and downtime.

Fitting an Air Line
Picture a technician replacing a leaking fitting on a cylinder. First, they shut off and exhaust the air supply. Next, they unscrew the old fitting, clean the port thread and apply a suitable thread sealant to the new fitting. After that, they screw it into the port and snug it with a spanner, then cut the tube square with a sharp cutter. Finally, they push the tube fully into the fitting, give it a gentle pull to confirm it’s held, then restore air and check for leaks.
Completing the Air System
Fittings work best as part of a well-built air system. Seal threaded fittings with our Loctite 55 sealing cord. On valve and dryer exhausts, fit our perforated steel exhaust silencer to cut noise.
Safety and Handling
- Depressurise first. Shut off and exhaust the air before connecting or removing fittings.
- Cut tubes square. Angled or ragged cuts don’t seal and may pull out.
- Push the tube in fully. A half-inserted tube can blow out under pressure.
- Match sizes. Use fittings that match your tube size and port thread.
- Respect the pressure rating. Don’t exceed the working pressure of the fitting or tubing.
Frequently Asked Questions
How do I remove a tube from a push-in fitting?
Exhaust the air first. Then press the release collar towards the fitting body and pull the tube out.
Why is my push-in fitting leaking?
Common causes are a tube cut at an angle, a scratched tube, a tube not pushed fully in, or a worn O-ring. Recut the tube square or replace the fitting.
What sizes do I need?
You need the tube outside diameter (for example 6 mm, 8 mm or 10 mm) and the port thread (for example 1/8″, 1/4″ or 3/8″ BSP). Tell us both, and we’ll match the fitting.
Can I reuse push-in fittings?
Yes, many times, as long as the collet and O-ring are in good condition and the tube end is cut fresh.
