Product Overview
AS568 PG Standard Size FKM FPM EPDM Silicone Rubber O-Ring Seals for Sealing Applications
Type: O Ring
Size: ID X CS, OD=ID + 2XCS
Product Description
An O-ring is a simple and versatile ring-shaped packing or sealing device with a circular cross section. The purpose of using O-ring seals is to prevent leakage and loss of liquids or gases. They offer simplicity, convenience, and small installation space requirements. With proper groove design, material selection, and operating conditions within the rubber material's temperature range, the seal can provide long-term effectiveness in both static and dynamic applications.
Size Calculation
O-ring size is determined by inner diameter (ID) and cross-section (CS). Calculation: Outer diameter = Inner diameter + 2 × Cross-section (OD = ID + 2×CS).

Fluorocarbon elastomers have grown to major importance in the sealing industry. Due to their wide range of chemical compatibility, temperature range, low compression set, and excellent aging characteristics, fluorocarbon rubber is the most significant single elastomer developed in recent history. Fluorocarbon elastomers are highly fluorinated carbon-based polymers used in applications to resist harsh chemical and ozone attack.

Material Characteristics Comparison
NBR Rubber Features
Nitrile rubber (NBR, Buna-N) provides excellent resistance to petroleum oils as well as mineral and vegetable oils. Offers strong resistance to heat aging - often a key advantage over natural rubber.
EPDM Rubber Features
EPDM rubber is a high density rubber primarily used for outdoor applications. It has dynamic and mechanical properties between natural rubber and synthetic rubber. Not recommended for continual contact with petroleum-based products or aromatic hydrocarbons.
HNBR Rubber Features
Hydrogenated Nitrile Butadiene Rubber (HNBR) is a special class of nitrile rubber that has been hydrogenated to increase saturation. Provides greater thermal stability, broader chemical resistance, and greater tensile strength compared to standard NBR.
SBR Rubber Features
Styrene-butadiene rubber (SBR) is a general-purpose synthetic rubber with similar chemical and physical properties to natural rubber, featuring better abrasion resistance, outstanding strength, and good creep resistance.
Neoprene Rubber Features
Neoprene (polychloroprene) is an extremely versatile synthetic rubber with over 75 years of proven performance. Used extensively in automotive under-hood and underbody applications.
Natural Rubber Features
Natural rubber is an ideal polymer for dynamic or static engineering applications. Not recommended for applications involving ozone, oils, or solvents.
PU/Polyurethane Rubber Features
- Good hydraulic oil and gasoline resistance
- Resistant to pure aliphatic hydrocarbons (propane, butane, fuel)
- Resistance to mineral and silicone oils and greases
- Resistant to water, oxygen, ozone and aging
- Excellent tear and abrasion resistance
- Available in multiple types and compounds to meet performance and cost requirements
Certifications
We hold the following certifications: ISO 9001:2015, ISO 14001:2015, ISO 45001:2018, IATF, FDA, REACH, ROHS, SGS, and more.
