Combustion O-rings on R&D 701 head, Same as ADA?

[kawyjunki]

Did a search but couldn't find any info that pertained to the R&D head.Just wanting to know if the cumbustion O-ring on a an ADA Dome will fit in a R&D rec head on a 701. I don't want to tear the head off to find out if I can keep from it. I have some extra ones for my ADA head and just wanted to have an extra set for the R&D head just for precautionary measures. If they are than I am set, if not I will obviously have to buy some. thanks

Well I may have too. I wanted to try and keep from that. I really thought someone might know instead of taking off the head since it is so close to the weekend I would'nt have enough time to get a new set if they were needed to be replaced, to reinstall the head. That is if the ADA's would'nt fit.

there are 2 sizes that Ive seen for most heads, the 043, and 153 in viton.

you can order a couple of each from mcmaster carr for about $15 shipped probably.

or get 40 of them for like $20.

You can get them from McMaster the next day and will have a life time supply.

Well I found out they are different size's. R&D head takes a -153. ADA is -043. Thanks for the input though.
