• Buna-N resists wear and tear and is often used with petroleum-based chemicals, fluids, and alcohols. Also called nitrile, this material is used in a wide range of sealing applications.
• Hytrel® is a thermoplastic polyester elastomer (TPE) that resists abrasion, high temperatures, and hydraulic oil and water. It is flexible and provides a strong seal.
• PTFE resists acids, ammonia, petroleum products, synthetic lubricants, coolants, and chemicals. This material is durable and rigid and often used with aggressive and corrosive materials.

The precisely measured inside diameter of the O-ring, typically in inches or millimeters.

The substance the product is made from — chosen based on application requirements like durability, temperature, pressure, or chemical/corrosion resistance.

Unit of Measure

Specifies if the O-Ring contains additives that allow it to be detected by metal detectors — useful in food and pharma industries.

The overall height or thickness of the seal from base to top, important for fitting within axial space.

The nominal (approximate) inner diameter of the seal, typically matching the shaft or bore it fits onto.

The nominal outside diameter of the tube, seal or fastener.

Indicates if the O-Ring is certified by NSF (National Sanitation Foundation) for use in potable water or food-related systems.

The specific design or model of the coupling, often identified by a part number or style (e.g. quick connect, camlock).
