Lockable lubrication nozzle of very high quality. The lubrication nozzle is fixed and opens with very low force even under the higher pressures. We at Germ have tested the nozzle and believe that it works perfectly. The lubrication nozzle has 4 hardened jaws in spring steel, integrated non-return valve, a unique locking mechanism that is easy to release even with back pressure up to 1000 bar. Has passed up to 2000 bar without leakage in an independent test. Working pressure 690 bar, burst pressure 1030 bar. Weight 85 grams.
