Can anybody help?
Are there any differences between black, brown or green viton flat seals. I have an application (Steam @ 140°C pressure 2.3bar) where I have validated the use of a 70 shore hardness Viton seals on some Solenoid valves. The seals were black in colour. Our production have been using black for the last year. My company have just had a delivery of brown seals which the supplier are claiming are still Viton at 70 shore hardness - but they feel phyisically softer to touch. (We do not have a hardness tester.)
Can anybody confirm what the different colour indicates?
I do not want to approve this unless their is a clear explaination for the difference in colour.
Thank you in advance.
