TA50597 - This is a package of 10 rubber O-rings for Tamiya damper shocks or other uses. Specs: i/d-3mm o/d-6mm & approx. 2mm thick. Comments: commonly used in the shocks to make a seal so that oil doesn't leak out, and dirt does not get in. These special orange rubber O-rings are an upgrade for leaky shocks or use in dusty conditions due to their softness.
