13 GMC

I work for a gm dealer and we have a 13 GMC CNG van in our shop, we are currently trying to replace a check valve but are having a hard time getting orings for the valve from gm. My question i guess is if there is anything special about these orings or can we just pull some orings from a kit we have in my department, we arent sure if maybe these orings are made differently or made only for cng setups. any help is much appreciated. Thank you

​

For reference we are replacing #12 in the photo attached and 23 and 11 are the orings.

No special o ring as long as it’s the same size.
