Nitrile Rubber O Rings/ Mini Oval Silicone Ring

A Mini Oval Silicone Ring provides a small shaped sealing interface where the mating outline is elongated. The ring should follow the intended oval seat without being twisted or stretched unevenly around its ends. Nitrile O-ring options are also named in this product family, making both shape and compound explicit selection decisions.

Measure the short and long axes along with the required section. A circular ring forced into an oval path may not reproduce the same contact distribution as the selected molded form. Keep the material suited to the fluid, temperature and care conditions of the joint. During fitting, settle the small ring into its locating feature before the mating part is brought down. Check the rounded ends for a folded section that may be difficult to see after closure. Use care during removal so a pointed tool does not cut the seal. Replace a damaged ring with the evaluated outline and material rather than relying on a similar diameter or matching color.
