R&R CYLINDER U-CUP SEAL CONVERSION

[Subculture]

Not sure if they'll fit. Not sure why you guys are having issues with o-rings though, but they should run wet, not dry on the bench. Also use PTFE grease or cooking fat on silicone seals, avoid mineral or silicone based greases.

I used standard 1/8" cup seals. Ideally you'd use a 4mm seal. Engel offers them, but I didn't want to wait or pay overseas shipping. I just ordered some standard 4mm nitrile seals. I think they'll work much better.

Bob, or anyone, what size u-cup seals were used in " The RCSubGuy UnPacks Some EPIC Subs and Gets a Scottish Flu" video?
