What is Push-Lok?

Push-Lok is Parker Hannifin's low-pressure system of hoses and push-on fittings. The system is designed for easy assembly, high operational reliability and flexible use in industrial low-pressure applications.

Typical applications

  • Industrial low-pressure circuits and return lines.
  • Cooling and lubrication systems.
  • Compressed air, vacuum and non-conductive applications (depending on hose type).
  • Machine rooms and workshop installations.

How to assemble a Push-Lok hose (step by step)

  1. Cut the hose at a right angle with a sharp knife.
  2. Check that the hose end is clean and free of burrs.
  3. Push the fitting all the way in, until the hose meets the yellow plastic insert ring.
  4. Pull gently on the hose to check correct engagement.
  5. Fit into the system – ready for operation.

Tip: Use different hose colours to distinguish media or dimensions in complex installations.

Push-Lok fittings

  • One fitting series that fits all 9 Push-Lok hoses.
  • Materials: brass, steel and stainless steel.
  • End configurations: DIN, BSP, SAE, JIC and ORFS.
