Expander Nitrile Rubber O-Rings Sealing Gasket (20 Pack – 1.00″ ID)
High quality expander O-Rings – 1.00″. For best results, always lubricate the o-ring with a compatible fluid (like petroleum jelly or grease) before installation. Slide the o-ring into place rather than rolling it to prevent twisting, which can lead to leaks.
