Standard and Custom O-Rings

The most common seals in manufacturing today. O-Rings are inexpensive and simple to install, yet they offer a wide range of applications. you can always depend on O-Rings for a reliable seal

Lusida Rubber Products offers a large variety of O-Rings, from custom sizes and materials to AS568 and ISO 3601 Standard O-Rings.

O-Ring Materials

We provide O-Rings from a choice of ten (10) materials. Other materials are available upon request.

Natural Rubber (NR): is formed from the bark of tropical trees. It has a wide variety of uses. Tires, airbags, flooring, gloves and lining are just some of the applications.

Polyisoprene (IR): it is a synthetic rubber, has the exact same molecular structure as natural rubber.

Ethylene Propylene Diene (EPDM): It is a very durable, high-density rubber making it a preferred material for products like gaskets, hoses and seals. The rubber is extremely resistant to heat, oxidation and weather due to its stable structure, plus it is ozone resistant.

Styrene Butadiene Rubber (SBR): It is more resistant to abrasion than natural rubber. It is predominantly used in automobile and truck tires as it stands up to heat and cracks and ages well.

Silicone (MQ): it is extremely resistant to heat and cold, being able to withstand temperatures ranging from -80ºF to 450ºF. Resilient and durable, silicone rubber materials resist prolonged exposure to sunlight, oxygen, ozone, moisture and UV light.

Butyl (IIR): It is impermeability to air and gases, and very resistant to water and steam, which is why butyl rubber is used in sealants for damp proofing, rubber roof repair and rubber membrane maintenance. First used as tire inner tubes, butyl rubber is now applied to sporting ball bladders, gas masks and protective clothing, vial stoppers, explosives, chewing gum and is even used as an additive in lubricating oils and motor fuels.

Nitrile (NBR): NBR is extremely resistant to oil and is therefore used in automotive seals, gaskets and other products that contact hot oils and fuels. Nitrile rubber is also a very resilient material making it ideal for products such as cleaning and examination gloves.

Polyurethane (PUR, TPU): have excellent wear resistance, high tensile strength and high elasticity in comparison with any other elastomers. Polyurethane rubbers are used where high abrasion resistance and oil/solvent resistance are required together.

Polychloroprene (CR): widely known as Neoprene®, was one of the first oil resistant synthetic rubbers. However, it has only moderate resistance to petroleum based oils and fuels. It can be considered as a good general purpose rubber with an excellent balance of physical and chemical properties

Thermoplastic Elastomers (TPE): It is used in a variety of applications in the automotive, construction, medical, food and beverage, electrical, appliance and consumer electronic markets.
