Hydraulic or pneumatic screw cap securing device - has link integral with mounting ring fitting by groove over flange

摘要

The screw securing device has a protective screw cap for screw- or quick-action-type hydraulic or pneumatic system couplings, and with a holder fixed to its top having a mounting ring at the other end. The holder is a link integral with the ring (2), while the coupling itself (5) has a flange (4) to secure the ring in the axial direction. This engages in a mating groove (6) formed in the ring. The flange can be chamfered on its face nearest to the cap, in which there can be a cylindrical recess (10) below the tapped portion (12) to accommodate the ring, of internal dia. slightly less than the external dia. of the ring.
