We offer a great car O-ring assortment for your automotive O-ring sealing needs. This includes BUNA-N O rings measured in both inches and millimeters. BUNA-N, which is also known as nitrile, is a synthetic rubber that's highly resistant to many chemicals, oils, fuels and even diluted acids. This makes it ideal for use in the manufacture of rubber seals for cars and auto rubber O-rings.
You'll find a wide variety of car seals and O-rings here, with various thicknesses, inside and outside diameters. There are several subcategories of air conditioning O-rings, including those designed for use only with R12 refrigerant, and Teflon-coated blue neoprene air conditioning O-rings for use with either R12 or R134A refrigerants. You'll also find a selection of green nitrile air conditioning O-rings, also for use with R12 of R134A refrigerants, several of which are direct replacements for O-rings found on Ford, Nissan, Toyota and Acura automobiles.
