Specify the material from the service conditions, not from colour.<\/h2>\n<\/div>\n

NBR is the standard flexible-element material for this range. If you need a different polymer or hardness, include operating temperature, oil or chemical exposure, starts and shock so the requirement can be reviewed.<\/p>\n<\/div>\n
