Shore A Description:
The hardness of rubber compounds is measured by the Shore A durometer; the higher the durometer, the harder the compound. Softer compounds stretch easier and seal better on rough surfaces. Harder compounds offer greater abrasion resistance and resistance to extrusion.
60 Shore A is softer than 70
70 Shore A is the standard
90 Short A is very stiff
PTFE exhibits some unique properties when used in O-Ring sealing systems, the most well known is its impervious nature to virtually all fluids and gasses from -100°F to 450°F. Only molten alkaline metals and certain halogenated compounds will degrade its integrity.
Standard Service Temperature: -110°F - +450F
PTFE material has almost universal chemical compatibility. One of the best solutions for low-pressure systems.
