Endurance Testing.

Endurance testing of our compatible equipment is always the highest priority. Both our Aeroquip and Duco compatible couplers utilise a tried and tested metal seated poppet for disconnect sealing. The endurance test has been developed to simulate multiple make & breaks with extended pressurised hold periods. No visible leakage was recorded at any point during the hold periods and after more than 200 full differential cycles.
