Customer Reviews (4.6 / 5 · 5 reviews)

Lucy B. ★★★★★

The rubber feels noticeably thicker and more durable than the o-rings that came with my housing. It seated perfectly in the groove on the first try, and I’ve already taken it on two dives without any water intrusion.

Sofia X. ★★★★★

I swapped out the old o-ring on my RM‑4K housing right before a dive trip and these fit snugly with zero fuss—just a smooth, reassuring seal every time.

Hannah ★★★★★

I noticed the seal on my housing looked a little worn right before a trip, so I grabbed this set as a backup. The o-rings fit perfectly around the RM-4K's sealing surfaces and I had the housing watertight again in a few minutes. No leaks at all across three days of shooting.
