E61 Brew Group Cap 16mm

The 16mm fit is spot-on for my E61 group—no wobble, no fuss when I lock it in. It's clearly machined to spec, and honestly, the peace of mind knowing the brew path is sealed properly is worth the few bucks.

Finally found a replacement cap that actually seals properly—my old one was leaking steam everywhere. The 16mm fit my E61 group head perfectly without any wobble.

The 16mm fit was perfect for my E61 group head, and the cap seals much tighter than the old one I replaced. It’s a simple part, but the build quality feels solid and snugs in without any wobble.
