Synapse DV mazdaspeed flange o-ring
 

Hi,

I lost mine. Any ideas where I could get a replacement?

maybe these http://synapseengineering.com/produc...ges-2-pcs.html

I don't think these are the ones.. i need the one which goes between the flange and the TMIC, eg this one: https://frsport.com/images/product_i...FS01-02@2x.jpg

This looks like exactly what you need..

Email them. They sent me one for $2 awhile back after I tore mine.

Photobucket fucked everybody. Your link is dead. No one can see it but you. You, and any of us who had used it would have to pay them outrageous money, I think $400 per year to be able to post our pics to third party sites. Assholes.

or go to a hardware store and get a 2x31mm o-ring... (I think I have gotten them from ACE in Vitan)

I've noticed and am just too lazy to host my pics elsewhere haha.

As far as my post goes, all I did was quote another post. Didn't actually have a pic or link attached.

Is that really the size? I'm talking about the one BETWEEN the tmic and the flange, which sits in the groove as per my picture?

I've created an issue in their support system with no response yet :/

I’m not 100% on how to measure an O-ring (correctly) but... the material is 2mm and the diameter edge to edge (keeping it as round as I can) is 40mm...


When I purchased mine used I had to replace it (the old one was rotted) I took it to the hardware store and literally sized one up... no leaks, 3 years later.. :) and I believe you are correct, the 2x31mm are the diverter air seals, not the flange o-ring (sorry about that).

Awesome! can you please measure internal diameter for me? As it seems that the ID is being used when sizing o-rings. Also, 2mm seems kinda slim, the groove in the flange is kinda deep, i'm not sure if 2mm is gonna seal it..

Best I could do, sorry :)

so... here is the thing... after taking it off (the engine was warm) the o-ring expanded and I was not able to get it back into the flange.. it is in the freezer now but I think my initial 40mm is correct (it was cold and went back in just fine).

after sitting in the freezer.. it was back down to 40mm and it fit (is installed once more)...

You are awesome! Thanks.
