Adding a Omni Swivel - O Ring Question

[noj3333]

I'm looking to add an Omni Swivel to my SP A-700 regulator. I'm also replacing the LP hose.

When I took the old hose off there was an O-ring on the regulator. I removed that O-ring, assuming the omni swivel would have all the needed O-rings pre-installed. I *think* I'm wrong, and I *think* I need to source a new O-ring for my A-700 before I thread the Omni Swivel on.

Can anyone who knows confirm that the A-700 needs an O-Ring, in addition to the O-rings that are pre installed in the Omni Swivel.

The picture that's attached shows the OLD O-ring that I removed, and I believe I need to replace.

That oring goes over the male side (on the left in your pic) and functions as a lock washer to hold the fitting on. You can reuse that one

Of course I took an O-ring pick to it, and mangled it while removing it.

Can anyone tell me to replacement size, and possible source for one?

Harbor freight has a budget pack of nitrile orings or since you just need one and they last for decades in that spot just ask at the scuba shop

@rjack321 thank you very much.

I actually picked up a multi-pack of scuba sized o rings... so I'll be covered going forward.

Try to push your orings from the side with your thumb and forefinger before picking
