hi, just wondering if any one knows the size of the o ring bvm uses on his pipe hanger?
thanks greg

OD of 1.5" will work by 3/32" thickness.

Hi,

I used a zip-tie back there. My O-rings kept breaking and leaving my pipe without support back there. I don't know about the BVM pipe coupling, but the JMP one had enough rubber up front to handle all of the vibration-related concerns.

It's a number 125 o-ring (3/32"w X 1 5/16"id X 1 1/2"od). Make sure you get a Viton o-ring. The cheaper nitrile (or buna) rubber ones the hardware stores sell can't take the high temperature and will break after a few runs. I usually put on two viton ones for extra insurance.

I have some extras left over that I'll never use. I don't know what postage to Australia would cost but if you reimburse me I can mail you a couple.

Thanks Thud driver, Shaun and Joe that was the info i needed. Joe- thanks for the offer but the orings are readily avaliable here, i just needed to know the part#. Shaun i thought the exaust would be too hot for a cable tie!
Thank you all, Greg

the black ones are for high temp and also have UV protection to prevent deterioration in sunlight. i use them on all my pipe retainers, included a pic of the DD as it's easier to see it
