Alternatives to OEM throttle body shaft seals?

[gusu]

So I've been looking to replace my TB shaft seals for a while now. But finding them for a 90 is a pain in the ass. Plus, I can't use Paypal on my only debit card due to a website I used getting hacked and losing people's Paypal information, so it's locked.

What I am wanting to know is if there are any alternatives to using the OEM seals, much like how a lot of us use Home Depot seals for our injectors. Maybe even just buying the seals from a site that sells hardware or something if anyone knows the exact specs.

If you guys know a place that I can buy them that it wont cost 400,000 dollars in shipping to have them delivered that would be awesome as well. I'm not going to spend 50 dollars on some seals that should cost two bucks.

I wouldn't I would get the ones for your car, call a dealership, call jnz, send a check, or money order, or credit card, or even have someone you know pay for it then give them cash.

Because they aren't round it will be difficult to find them. Rtmracing has the all rubber ones, not sure what shipping to the states would be though.

larger o-ring = 1/2" outer diameter, 1/16" thickness
smaller o-ring = 7/16 outer diameter, 1/16" thickness

1990 Throttle Body uses the Chicago Rawhide CR 3930 seal on the spring-side and the smaller CR 3030 seal on the TPS side.

Full specs:
3030 CR 8x12x3 HM4 R
3930 CR 10x14x3 HM4 R

Huh?

I don't know how to describe it, if you have seen one then you know what I am talking about. O rings are circles and are easy to find.

So you mean it's not a tube in the shape of a circle, but instead has some height to it? If so, then yes, that's normal. They make seals like that in a variety of shapes, as noted in the above linked threads.

These seals will only fit on one side of the '90 throttle body. The other side is a different dimension (smaller). The best way for the OP to go would be the Chicago Rawhide part numbers in the linked threads. twicks69 most likely has these in stock.

 

[killahb33]

Yes exactly, ramen has all the info he needs.

 

[Mello]

His talking about the cross section when referring to "round".

 

[My1GLaser]

I got the Chicago rawhide seals from NAPA once. I got them from Kamen direct the other 3 times. $20-25 shipped IIRC

 

[twicks69]

I usually keep a few dozen of the Chicago Rawhide CR3030 & CR3930 on the shelf. Pm me if you need a set.

 

[Boosted6]

I could not find the seals so I used O-Rings and so far no issues.

Found out NAPA sells 3030 on their site but the 3930 I can't seem to find.

But! I did find Motion Industries - Product Search sells both.

Links.
