Pneumatic fittings: how to choose them  

Pneumatic fittings are components that allow connections between valves and actuators within a pneumatic circuit. The basic elements are tubes and threaded parts. Before buying a fitting, it is important to know what its application will be. There are different types of pneumatic fittings on the market, each with different characteristics. The main factors to consider are:

  • type of hose required, which can be metric, thermoplastic or metallic
  • type of thread of the fitting needed, which can be tube, English tube, metric thread, straight thread
  • air pressure 
  • possible vibration problems
  • the material of the fitting: usually materials are brass, stainless steel, thermoplastic, nickel-plated brass)

The main types of fittings are:

  • Compression: very practical as it does not require countersinking or welding. 
  • Compress-Align: pre-assembled fitting with captive sleeve. This also requires no welding or countersinking 
  • Metru-Lok: pre-assembled one-piece fitting with captive sleeve
  • Poly-Tite: the acetal copolymer sleeve withstands even high stresses caused by compression; 
  • Hi-Duty flared hose couplings: the sleeve is waterproof and perfect for high-pressure applications
