O-Rings for Toomeys
Anyone know the size of o-ring for Toomey pipes? Anyone know if they make silicon ones and where to get them? Just read an earlier post where I hear they are heavy junk. [DISAPPOINTED BUT RELIEVED FACE]

Re: O-Rings for Toomeys
Not sure on the size. Could you remove a pipe and measure one up? They are most likely a standard imperial ring.

Re: O-Rings for Toomeys
I can. I just wondered before I pull the pipes off and can't ride if someone would know the dimensions. The bigger question is are they available in silicon?

Re: O-Rings for Toomeys
The o-ring I measured is the stinger tip (end cap) o-ring at the very end (snap ring holds the aluminum tip in place @ exhaust exit. My measurements: 1.958" ID X 2.280" OD X 0.135" Width. The closest I could find was #226 Silicone O-ring @ McMaster-Carr for $9.64 (10 pack). Might be worth a try to see if they fit. I remember finding snap rings at Fastenal for the J&R pipes i have o n the RD350 A/C. I had a machinist machine down some toomey end caps to fit the slender ends. Works like a charm, also used toomey perforated cores too. Problem solved!

Re: O-Rings for Toomeys
Are you talking about the one at the front of the silencer? Just to clarify there is an o-ring on the inside of the pipes at the engine flange end as well.pushstartrearset wrote:The o-ring I measured is the stinger tip (end cap) o-ring at the very end (snap ring holds the aluminum tip in place @ exhaust exit.

Re: O-Rings for Toomeys
Not at the flange where it (header) mounts to the cylinder or (pictured) where it mounts to the end of the expansion chamber @ exhaust end (that's a banshee T5 can i think).... see image (below).
CORRECTION: Looks like both silencers pictured are T-5 toomeys. You can tell by the "hangars" welded near the center and top of silencer can for banshees. I would think the o-ring would be shared or the same. Someone correct me if I am wrong.

Re: O-Rings for Toomeys
I thought that one is the one you were referring to. I need the dimension for the o-ring at the cylinder end where the header mounts over the flange. Would you know that dimension? Do you have o-ringed headers as well?

Re: O-Rings for Toomeys
Toomey has them in stock. I ordered a set and had them in 4 days.
I love the smell of Blue Marble in the morning!
