What does pneumatic connection technology include?

Between air preparation, valves and drives, connection technology ensures that compressed air arrives without leaks and with minimal pressure loss. This includes push-in connectors and push-in fittings, plastic tubing, rotary distributors, manifolds and seals. This category features CRQS push-in connectors in T, Y, L and bulkhead designs, GF rotary distributors, PUN-DUO spiral tubing and sealing ring assortments. These components are used in mechanical engineering, assembly technology and maintenance wherever pneumatic lines need to be installed quickly and reliably.

Selection criteria and versions

  • Tubing outside diameter: fitting and tubing must match exactly, e.g. 12 or 16 mm.
  • Thread connection: for push-in fittings, the thread such as G1/4 or G1/2 defines the connection to valve or cylinder.
  • Design: straight, L, T or Y shape as well as bulkhead connectors for passing through walls and panels.
  • Material: the CR prefix used by FESTO identifies corrosion-resistant versions for demanding environments.
  • Tubing type: straight tubing for fixed installation, spiral tubing for moving consumers and hand tools.
  • Rotary distributors: provide air supply to connections that can be rotated into position.

Frequently asked questions

How do I release a push-in connector?

Press the release ring against the fitting while pulling out the tubing. The line should be depressurised.

Which tubing fits my push-in fitting?

The tubing outside diameter stated in the type code is decisive. Also make sure the tubing material suits your environment.

What is a sealing ring assortment for?

It is handy for maintenance and assembly, allowing threaded connections to be sealed quickly without ordering individual parts.
