Useful Info:

Pipestock are proud to supply this new cutting-edge compressed air distribution system. The aluminium Prevost Fittings are designed to be compact, lightweight and durable enough to withstand the harshest operating conditions.

Please note fittings and pipe are not interchangeable with other product ranges.

Installation Instructions:


  1. The pipe must be fully inserted into the fitting – to do this, simply mark the point using the tightening key, loosen the locking nut and with one motion twist and push the pipe into the fitting – it may help if you use a lubricated spray (non aggressive)
  2. Use PTFE tape on all male threads unless a seal is supplied
  3. Make sure the pipe is straight and level, clamping every 3 metres and where it may be necessary to ensure a strong bind to the wall or ceiling of the building
  4. Tighten all fittings by hand and once the system is in place, tighten using the PPS1 CLE key and torque wrench to the following points, starting at the lower setting – for example 25mm fittings – 21-35Nm
  5. Once all fittings are tightened, set the compressor at 2 BAR and run for 5 minutes, then check each fitting for leaks, adjust if needed, and repeat the test at 8 BAR. Again check all and if the system is leak free, your customer is free to use the system
