Hi, have had the Rolock 90 system for several months (~20 dives) with no issues and appreciate the bayonet and twist locking. Thought I should add some spare o-rings to the save-a-dive kit as although I lightly lube the mating o-ring, our dive sites are often silty sandy with some abrasion. Through the forum and discussion on Rolock 90 o-rings and looking at the Rolock website, ( O-rings for bayonet lock (from 2006) – Rolock ) I sourced and purchased the O-Ring: Buna-N, Round, 2.5 mm C.S., 96 mm I.D.
My query is that the o-rings at 96mm I.D. appear to be smaller than the groove on the drysuit side ring which measures ~104mm with vernier (see pics)
First photo shows a new o-ring inside the one I removed with two more new o-rings. (is the old one stretched?)
2nd photo of vernier measuring the drysuit ring ID on the o-ring groove.
The new 96mm o-rings do fit the ~104mm groove with a gentle stretching. Is this normal?
