Jet purge valve

[huaxing huang]

Hey guys I recently changed my intake but needed to swap back to my stock air-box but lost the o ring gasket under the jet purge valve and I can’t find a part number for the correct size of the O ring. Currently I just used some RTV and sealed it off ,but It would be great if y'all know a good replacement.

I assume you checked Honda's exploded parts diagram and the o-ring isn't sold separately.
Me, being an engineer, would measure the o-ring groove with calipers and use the Parker catalog guide to find the o-ring size. McMaster.com is the engineers go-to for parts. Good hardware stores have selections too.
Only use "sensor safe" RTV on the intake or cam cover.

I don't have a part number I can share but I can tell you it is not a standard o-ring. Someone like McMaster very well could have something (fingers crossed!) but be sure you are getting enough thickness to fill both the width and the depth of the groove.
