Polybushes

[stuffedpike20]

A simple question...are green polybushes harder than blue ones?

I think the answer is there is no agreed colour code so the elasticity cannot be judged by colour. Different manufacturers use different colour codes. The only way to know is if the manufacturer quotes a Shore number.

Joseph Whitworth standardised things, he saw the problem with people doing their own thing.

Most poly bushes no matter what colour are around 70 shore

Here is the shore gauge I have and which allows me to measure the shore hardness of rubber and poly bushes.

Thank you all.

The only reason I asked is because ESM showed blue ones in an advert, and then sent me green ones.
