Pneumatic fittings – general information
Our company offers a broad range of pneumatic fittings, therefore it is always possible to match the appropriate solution to specific working conditions. Our Customers may choose among the following types of fittings:
- Brass and plastic push-in fittings – easy, quick and very user friendly. Push-in fittings are manufactured in a huge number of shapes, however, a complete system can be built using just four basic shapes, thus reducing the overall cost of the system. The push-in fittings are divided into three series: R series – general purpose, for hoses with outer diameter from 3 to 14 mm, RL FOX series – reduced outer dimensions and economy version push-in fittings – S series.
- Push-in fittings designed for the food industry – highly specialised variation of push-in fittings, which is highly resistant to detergents and other chemicals. Both the push-in fittings made of nickel-plated brass – F-series as well as acid-resistant steel are available in this version.
- Cutting ring fittings B series – designed for copper and plastic pipe assemblies. Particularly recommended for installations, where vibrations may occur. Can be used at high working pressure – 60 bar.
- Finger tight fittings C series – to assemble the fitting, the hose must be pushed onto the fitting and tightened up with the nut. Maximum working pressure of finger tight fittings is 18 bar.
- Finger tight fittings D series (banjo) – these fittings can be connected in any required position and also connected with R-series push-in fittings. Their maximum working pressure is 18 bar.
- Threaded fittings A series – made of nickel-plated brass or AISI 316L steel. It is usually required to use additional sealing to make the connection of this type of fittings tight.
- Function fittings LINE ON LINE – is a unique range of products designed to be installed in pneumatic systems. Their distinctive features include: high efficiency, small dimensions and compact design. The modularity of their construction allows parallel, serial or combined parallel-serial connection.

FAQ – Pneumatic fittings:
Pneumatic push-in fittings are the most popular because they are readily available, user-friendly and easy to install/disassemble from the hose.
A pneumatic threaded fitting consists of a body onto which a hose is pushed and a nut with which the hose is clamped. Due to the construction, it is very important for both hose diameters (outer and inner) to be the same as the dimensions of the fitting.
It is not possible to make a correct connection by using 8x5mm hose for 8x6mm fitting.
For equipment where vibrations, displacement or hose jerking may occur, it is best to use threaded fittings or fittings with a cutting ring.
Yes. There are special “high-pressure” push-in fittings designed for lubrication systems, with working pressure of up to 30bar for air, and up to 150bar for lubricants.
The vast majority of connections in pneumatics are made using fittings with BSP parallel threads and an O-ring seal. Unlike sealing by contact between threads, they do not require Teflon thread sealant, which could be a source of contamination for the pneumatic system. The exception is joining uneven (curved) surfaces where an O-ring may not provide sufficient leak-tightness.
