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

Unit of Measure

The nominal size of the product, typically indicating dimensions (width x length) or the diameter of the hose that a coupling fits.

The depth or gauge of the material, typically in inches or millimeters — influences flexibility, durability, performance, compression, and application suitability.

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

The horizontal measurement of the sheet's surface across its shorter side.
