Tail light gasket replacement?

Does anyone know of a replacement for the 710 tail lamp gasket/seal (which is no longer available)?

One of mine was soft rubber/foam (OEM I think), but the other was some rubbery abomination that was a total bastard to get off-- the lens was so stuck on so hard it seemed to be glued in place.

I had to grind down an 8d nail, removing just enough of the head so it would fit through the lens screw hole, but leaving all the head on one side so I could hook it on the inside of the lens and pull. Moved the entire machine (on a level slab) and was about to give up... but finally decided to just pull as hard as I could and if the lens broke then it broke. When I finally got the lens off (*&!@%!#), I had to remove the old seal in pieces; it was toast. What a hassle!

The OEM seal (09-80-01) is about 4 7/16" (112mm) OD and ΒΌ" wide (6mm), so ID is about 100mm.

I've been looking for foam or rubber tail light gaskets or anything else that will work (some plumbing stuff is close),.. but before I spend more time on this, has anyone been here before and found a replacement??

Thanks...

BTW, here's the closest plumbing match I've found so far

Both of mine were *BRUTAL* to get apart, but I mostly salvaged the gaskets. I keep watching SAV's site to see if they ever get stock again...

I emailed SAV asking when/if the OEM ones will be available again. We'll see...

There are many places that will make custom gaskets out of rubber, silicone, etc, sometimes in small quantities. If enough people needed them if might be economical to have some made. It's a super-simple design... and who knows, SAV might be interested in enough of them to make it feasible (if they get on board, having no other source).

Off-the-shelf would be better and easier, though, if you just need 1 or 2....

mcmaster.com has many, many o-rings, etc.

Maybe this: https://www.mcmaster.com/1302N402

I thought about going the O-ring route, but both the lens and the back of the tail lamp box have thin sharp ridges that are meant to dig into the flat gasket-- to be sure it seals, I suppose. Used gaskets have an obvious line where the ridge was (see attached)... so I think staying with a flat gasket would be best. I'd go O-ring if I can't find anything else, tho...

I don't think an o-ring is going to work well for the reasons already stated. I think it needs to be a flat squishy (low durometer) gasket.

I heard back from SAV... the OEM gaskets are not available and "We don't know if we will be able to get them again.

Silicone seems like a good material choice, so I asked the Mason Jar people where they had their gaskets made, and it's China (color me surprised). The contact they gave me said they mold gaskets, so a custom mold would be needed and the minimum order is 2000 pieces.

For smaller orders there are many custom gasket houses that die cut, water-jet cut, etc. I asked SAV if they would be interested in joining a group purchase (maybe a hundred or two?) to keep unit cost down. Will report back.

SAV says they sell/sold so few of the OEM gaskets that they are not interested.

Will look around once more for an off-the-shelf solution before pursuing custom....

If we find the right material, we can probably just laser cut what we need. Or, honestly, if we have the right material we can just cut it by hand with an exacto knife

I don't have a laster cutter, but compass cutters/circle cutters are cheap and work way better than cutting by hand; X-acto and many others make them. I've used them on paper before, but they would surely work on rubber or silicone sheet or whatever,

Still working on some OTS possibilities, tho...

I bought a couple gaskets meant for dairy equipment of some sort; they're close enough to work, though I wish they were a little wider, 1/4" instead of 3/16".

The other off-the-shelf possibility was a Sioux Chief No-Putty Gasket for Kitchen Basket Strainer, Part# 290-20320, though it would take some slight mods to fit.

I have 3D printed my gaskets. I can share the files with you or if you have time, I can try to print them for you. 404 747 12 nine four Jerome

Thanks for the offer... I've got one more off-the-shelf gasket order coming, to see if it fits better. If not, I may take you up on that... either way I will report back.
