Hi Cupla Ace is a plastic coupling suitable for both air and water applications. Since it is made from plastic, it is lightweight and minimizes risks of damaging or denting various surfaces. However, it boasts a working pressure of 15 bar, which is more than the pressure ratings of most Cuplas made from steel.

Aside from a one-way shut-off valve structure, Hi Cupla Ace boasts a built-in automatic locking mechanism, which keeps it securely in place. All that is required to connect it is to push the plug into the socket. It also comes with a plug and socket with hose guard nut (refer to product notes for NK Cupla Hose /NK Cupla Cpil Hose). Once it is coupled, air starts to flow from either the plug side or the socket side.
