Question Rubber o-rings used on 1 inch strobe arms? SOLVED !

[umbert]

Hi All,
My strobe light arms have those common 1 inch balls with rubber o-rings in them. Those o-rings are deteriorating / falling apart. Anyone of you guys ever replaced those? any good source to buy them? like maybe McMaster Carr store, part # ? or at least sizing? I could measure them myself with caliper, but given the fact that those are broken or stretched, I may buy a slightly out of size ones...
I appreciate any help here!

Per Ultralight they are Size 209 Buna 70D.

The 209 O-rings can be found in Harbor Freight kits, Ace Hardware, Amazon, the O-Ring Store. They are nothing special, a common size.

If your mounting balls are the standard size then the 209 works. But if they are XIT, they will be different and Mike has at least 3 sizes.
