Molded 'O' Rings Compounds |
Standard 'O' Ring Compounds
A full range of quality 'O' rings are available in commercial and military specification material. |
In addition to the American Standard AS series, non-standard requirements can be accommodated by either vulcanizing from close tolerance 'O' ring cord or choosing from a wide availability of metric sizes. |
