Revisiting this topic...I just paid .95 cents a piece for mine from the dealer. Hogrida, are you sure these will hold up to the heat like the ones the dealer sells? I looked at the ones from Lowes and they don't say what they are made of.

 

There is only a few types of orings. The black ones are fine for most applications. If your o-ring is brown, then its for high heat applications. You can find o-rings much cheaper at any hydraulic store. Part of my family business is hydraulic repair. I got a bunch of o-rings at home from the shop. We pay 3 cents per o-ring in this size.

 

Yup, go to any industrial place that sells orings etc. The size is 9/16" x 7/16" x 1/16" and the reference number is 013

 

Great info.....glad I searched. Been looking for this info.
Thanks to all.

With the info here I picked mine up and the local bearing house for .10 cents each if I purchased 20 or more. So 2 bucks for 20.
Thanks for the info

 

$2.80 for 100 of them http://www.mcmaster.com Search 1879T19

 

My o-rings are long gone. I've been using Permatex Thread Sealant, and have had no leaks since: http://www.permatex.com/products/aut..._with_PTFE.htm
