Polyacrylate (ACM) O-Rings

Polyacrylate (ACM) o-rings are copolymers of ethyl or butyl acrylate with a combination of chlorine, acid, amide or epoxy compounds. Optimal environments include engines and transmissions with good resistance to petroleum fuels and oils, automatic transmission fluid, type A power steering fluid. Good resistance to mineral oil, sunlight, oxygen, and ozone.

Engineered Seal Products has the expertise and inventory for your ACM o-ring applications. For over 50 years, ESP has been the leading engineering, quality, and supply chain choice for both standard and custom sealing applications. A seal, no matter the application, has to do just that.

Temperature ranges will apply to the majority of media for which the material is potentially recommended. With some media however, the service temperature range may be significantly different. ALWAYS TEST UNDER ACUTAL SERVICE CONDITIONS.

ESP’s shelf life recommendation is based on the ARP 5316 standard and intended to be utilized by those organizations who do not already have specific recommendations for the control of elastomeric seals. It should be noted that the packaging of the elastomeric seals prior to assembly into a product is an integral part of the controlled storage procedure. It provides a positive means of product identity from the time of manufacture, to the time of assembly.
