Title: Coolhead o-rings
Post by: Powerstroken on March 30, 2015, 07:41:01 PM

I bought a o-ringed cool head from a member on .net a few weeks ago. I went to install it today and the outer o-ring was way to big. I was wondering were I can get replacements. I see that rocky mt. Has them but I don't know if they are for my head or not. Can anyone help

Normally you take your head down to an o-ring shop like air oil products to get them to measure and give you the right size. o-rings are usually $1 each with a $5 minimum

Pro design sells the o-ring set but last time I got them i think they were around $25 at the bike shop. Tony has a better idea to get them through a supplier that carries o-rings. Much cheaper option.

http://www.mcmaster.com/#O-Rings You just have to be able to measure it. When you go in to an o-ring shop they have a cone they through the 0-ring on and it measures the size. Then they try one on your head to make sure it fits.

The one I have in my town is AOP  http://www.aoptec.com/pages/contact-us.html

How big of a bore can you generally go with these o-ringed heads. Skeans1 I found a Parker store about 1/2 hr from me thank you

just make sure you purchase the Viton oring(they come in brown or black) for the oring closest to the bore, on the outer oring i still use viton but it is not mandatory
