O-rings for LP hose swivels

[sambolino44]

How can I find out what size of O-rings go in the universal swivel on my LP hose? It's marked "OmniSwivel International".

Can't tell you specifically, but from what I've been able to dig out it could be a -010 o-ring:

If you remove the o-ring - gently - you may be able to get approximate ID and OD measurements and can compare with o-ring specs.

Most hoses use a 2-010 at the 2nd stage connection. Scubapro uses an oddball o-ring on their superflow hose which I replace with a 7mm OD x 1.5 MM wide that appears to be a bit large but works OK.
