HMMWV rim O rings

ok i just got one frome them thanks for the post.

There are 3 Different O-Rings ....

One for the 8-Bolt Rim...Black

One for the A1 12 Bolt 2 piece Rim...Black

Once for the A2 12 Bolt 2 Piece Rim...This O-Ring is Red in Color and much Thinner then
the First 2 Listed.

And Possibly a 4th for the Newer 24 Bolt Rim, I have not seen these yet....

14.25 is WAYYY to much for those black orings. Check McMaster-Carr search for 9452K451 that is the black oring for the 12 bolt rims.

I did an advanced search in the hmmwv forum, for "o-ring" and found this! (part numbers)

Here's all of the search results.

btw, I only did this one search, and it took about 30-45 seconds.

Having done the search, I see there are multiple orings. I'm opening this thread in hopes of some more clarity. I've read multiple posts and threads plus taken measurements. I've seen the debate over using a 457 vs a 458....both of which are 1/4" diameter.

My rims are the newer style. They are two of the same style and number rims, both have 3/16" orings in them, 15" OD, but one is black Buna N and the other is red.....but seems to have the same durometer.

My problem is that what I read calls for a 1/4" oring while what was in it is a 3/16". Any comments on those two diameters in the later style wheels (2000+) will help me in choosing. Note that the 3/16 standard Buna N is either tight at 14.5" od or the next size at 15.5" od, which is loose. The trick I understand on the "too big" diameter size is to put it in the refrigerator to shrink it a bit.

Help in sizing please, since what I read contradicts the oring that is in my wheels.

I went back to the orings I took off that were both in reasonable shape but have taken the triangle shape somewhat. I can't see any way a 1/4" o-ring would work without it holding the steel rims apart or squeezing excessively.

I'm going with the black Buna 70 #384 which is 15" ID x 15 3/8" OD x 3/16".

Where can I get the o rings for the HMMWV rims? I have both styles. Yes doghed I did search.

You have both styles of what? I know of 5 different rims. And 3, maybe 4, orings.

Sorry, this is an old thread but came up high on the search. Unfortunately Doghead's links don't work and the OP never comes up with part numbers. Myself, I have 2 rims with 12 bolts and the very small o-ring, I believe is 3/16".

The #384 Buna N 70 duro o-ring came and it is too big. I'm going to the #383.

Help me out if you know the number for the 15" od x 3/16" (or slightly smaller, maybe metric size), right now I'm in trial and error mode.

The red o-ring seems to be the current issue and fits most wheels. It is in the 24 bolt even spaced wheels I have. AMG 12460388 Appears to fit most 12 bolt also. HPG lists it as superseding previous ones.

There has been too many moons for me to say for sure. I believe they did but I have one set on a trailer that is not staying up long term.

That is a 3/16" dia x 14.00 inside and buna N, 70 duro...sounds right but I don't have any apart to measure. I do more 20".
