Trying to get ready for my Thanksgiving trip (Pennsylvania to Myrtle Beach South Carolina) and seem to be chasing Grimlins.

Yesterday I serviced oil, adjusted and lubed chain, cleaned bike ran up, checked oil...all looked swell.

Get ready to do a little joy riding this morning and it ran on two cylinders blowing black smoke. *****, fowled plugs. Removed tail section, removed tank, pulled plugs, all were VERY wet. Cleaned, re-installed everything, took a quick trip and noticed the wonderful aroma of fuel. Sure enough, now my quick disconnectors are leaking. Apparantly pinched an o-ring. Came home, put on my mechanic clothes again, pulled tail section and removed o-rings. Drove to automotive store ($6.50 for two small containers of assorted o-rings). Came home and installed. Seems to run fine now, no apparant leaking. I'll ride a bit later today...just got tired of dressing and undressing into riding gear (40F degrees today, starten to get a bit chilly).

Wish me well...I leave early Wednesday morning :-D

Sport, I too had a leaking union after replacing the fuel tank. Although I had a box of O rings in the garage, I bought new Triumph O rings despite the ridiculous cost because I assumed that they would be viton or similar material to withstand contact with petrol. You will find that rubber O rings soften, swell and eventually leak, so be wary.
Good luck with the trip.

Thanks for the reminder Dusty.

I plan on going to the dealer tomorrow (time permitting). I will then buy several o-rings for future needs. I realize I'm taking a gamble by purchasing 'generic' o-rings, but it was necessary to get me by until I can get to the dealer.
Anybody know the P-# to these I.B.B. (Itty Bitty Bastards)? How about a cross-reference #? When I repaired aircrafts I could get what I needed, but I've since lost that convenience.

Sorry, Sport, if I was stating the obvious! I'd have done the same in your position, and the rubber Os will be OK for a while.
I can't help you with a x-ref but the Triumph part number is T1240181.
Enjoy the trip.

For what the dealer will sell you two o-rings for you could buy us all some HERE.

Just as an example I looked up a 1/16" width x 3/8" OD in Viton material. Cost $6.50 per 100! Their website won't let me bring up the individual page so you'll just have to use their search function. Don't worry their search function works like all the others SHOULD work. Just type in 'o-ring' and you will get to their list of products.

Stlakid,

Thanks; This is what I was looking for.

Just need to be sure they are fuel resistant. I'll check into the differences between the Viton, PTFE, and the Kalrez o-rings.


BTW, how's sunny CA? I'm originally from the Central Valley (Fresno). I truly miss all the wonderful roads (Sierra Nevada's)!

On the first page of any listing McMaster gives useful information on the items you are looking at. I saw a list of the different compounds and what they were recommended to be used with.

The weather here has been ABSOLUTELY GORGEOUS! It hit 90° today. Where I live it was in the low 80's and not a cloud in the sky. Not trying to make you feel bad but the last two weeks have been just perfect California weather even though they say it's supposed to be around 20° cooler right now.

Like I said for some reason their site won't let me post a page so here's a portion I cut-n- pasted..................

Buna-N (nitrile) is used in oil applications. Temperature range is -35° to +250° F. Durometer hardness is A70. Meets SAE J200. Color is black.

Viton has excellent chemical and oil resistance. Temperature range is -15° to +400° F. Durometer hardness is A75. Meets SAE J200. Color is black.

Silicone has good low and high temperature resistance. Temperature range is -65° to +450° F. Durometer hardness is A70. Meets FDA 21CFR.177. Color is red-orange.

EPDM (ethylene propylene) is used in applications requiring weather resistance. Temperature range is -65° to +212° F. Durometer hardness is A70. Meets SAE J200. Color is black

There is more info on the first pages of the listing.


I think I'd pass on the Kalrez stuff. I looked up a 1/16 thickness 1/4" ID and 3/8" OD........$22.00 EACH!! The Viton's were $6.45 for 100.

That's the way to go! I paid about $4.20 (£2.30) EACH at my Triumph dealer! I'll now buy some at these low prices so that I can change them every time I have the tank off without thinking about the cost.

just a little aside, you can visit any scuba diving shop and get a set of "save a dive" o-rings. Most are viton and very durable (3000+psi)

They come in a variety of sizes and are quite cheap.
