Paterson deksel & trechter voor System 4 tanks

Needed a replacement after my original one cracked, and this spare fits the System 4 tank perfectly. The UK build quality is evident in the thick plastic—it feels sturdier than the original I had.

The internal funnel fits snugly into the tank, so no more fiddling to keep it seated during inversions. Replacement parts like this are a lifesaver when you're mid-session and realize the original is cracked. Glad it’s made in the UK too, feels solid.

Dropped my old lid and cracked it, so this spare saved me from buying a whole new tank. The funnel sits flush inside and the lid seals with no light leaks during inversion. Genuinely relieved these parts are still made in the UK and easy to find.
