who who sells them individually... I just need 4 inner seals...

 

Mazdatrix has them. You may want to check with Atkins as well.

atkins isn't answering there phone, they did this morning... its only 430 no time zone diff...mazda trix is 20 bux a pop.... expensive.... why can't we find the right size for the one's from mcmaster... been searching no luck....

 

Maybe ask Jeff (88IntegraLS). I know that he has used the Teflon Encapsulated seals before, but I don't remember if he used the Mcmaster ones or the RA ones. I believe that he went back to using Mazda ones though, but I am not sure. I know that the Mazda ones are expensive. You can almost buy a whole gasket set for what just the coolant seals cost. Why are you having trouble with the McMaster seal? Do you not have the part number, or is it that you can't find them in the catalog?

I'm actually looking for mcmaster seals for a early 13B 4 port... talked to atkins this morning they said that there not the same size as later 2nd gen seals. they are the same size as 12A seals.. so so no go on mcmaster inner seals that are cheap... due to size diff... it looks like I'm going to have to measure the groove and search mcmaster site for right size... I never really wanted factory inner seals, but not really getting much of a choice....

 

Hey I have a 12a. What size or part # viton ring would I order on mcmaster.com?

 

I have an extra SE housing (uses the same seals as yours). I can try to measure the groove for you if that will help at all. It would at least give two independent sources of measurement, so that you would be less likely to order the wrong ones.

dude that would be sweet gonna measure tomarrow.... the thing is I talked to a friend of mine that has been in this biz for quite sometime he says its a no go mcmaster doesn't carry that size... well see I might just cut a splice at proper side.. use extra hylomar... or i'm thinking of using teflon encapsulated 18 guage wire... just might try it......

 

Okay,

I get about 0.1285" or so as the width of the groove and about 72.2 cm = 28.425" as the circumference. This means the diameter should be 28.425/3.14159 = 9.048". McMaster-Carr has an FEP-Encapsulated o-ring that is 1/8" thickness (fractional) with a 9" i.d. and a 9.25" o.d. This is probably the closest that they have. The actual i.d. is 8.984" and the actual o.d. is 9.262" which gives an actual thickness of 0.139". This should work, although it may be a bit big (may need some extra hylomar to hold it in place). If you need a hand when you rebuild, let me know. I will come down and give you a hand.

(Same as 9319K99)
FEP-Encapsulated Silicone O-Ring AS568A Dash Number 270
$ 11.78 Each

Just to give you a little more confidence, it appears the 2nd gen guys are using the -175s which are 9" i.d. and 9 3/16" o.d. So, the only difference appears to be with the thickness of the groove.

lol you so fast... well the funny thing is I've already ordered from mcmaster.. all the seals as if I was rebuilding a 13B.. I'll use them anyways, on other motors.. now I'm trying to tackle this issue... I'll be ordering those tomarrow... hey that would be great. I'll get 88integrals to show also. tryin to get this gtu together to roadrace.. very grass roots shell motor ecu one seat....

 

I hope those work out for you. If they work, we know that others will be able to use them in 12As and early 13Bs. If you have your housings out, go ahead and measure them just to verify. I am pretty sure on my numbers, but I don't want you to order the wrong part on accident. I would be happy to assist with the rebuild. Just let me know when you need the help. Sounds like a cool car.

well guy's i recieved my mcmaster inner coolant seals... I ordered these for my s4TII engine... I was going to just see how much biiger they were.. since people are telling me that the inner coolant seals for early 13B's are diif from later 13B's, but same as 12A's I called atkins they told me, they are the same size as 12A??? well the coolant seals for my TII engine fit my early 13B 4port perfect.. same no diif wtf.... people... well now i no, the truth... and if anybody else wants to no... well good luck......

 

Glad they fit. The ones that I listed are a bit thicker, than the second gen ones. I hope the TII ones will be thick enough of seal properly. Let us know how it goes.
