Quick opening closure manufacturer?

[RubeGoldberg]

I am trying to do some research to find the specific o-ring sizes for our various QOCs (quick opening closures). So far I have identified Tube-Turn and Huber-Yale as two manufacturers within the plant, but one manufacturer remains unknown. The only information still visible on the unknown QOCs is as follows....

"UNIBOLT"

"1440 CWP J255 2W.58"

as well as what I believe to be part numbers: TC-1227, TC-1228, and TC-3258.

If anyone has anyidea who or what company I can contact for specific information on these unknown closures it would be greatly appreciated!!!

Thanks

Unibolt was a trademark of Thorhill Craver, hence the part numbers TC-....I believe Cooper Cameronbought up Thornhill Craver. I have also seen WKM use the name Unibolt. How old is this equipment you are examining?

From the best of my knowledge, the QOCs were installed sometime around 1974 give or take a year.

So far I have not been unable to find any information regarding Thorhill Craver other than their involvement in manufacturing chokes.
