Neoprene (CR) O-Rings at NewDealSeals

Neoprene O-Rings (also CR O-Rings), derived from the world’s first synthetic rubber known as Chloroprene, are celebrated for their exceptional sealing properties and versatile applications across various industries. At NewDealSeals, we take pride in offering high-quality Neoprene O-Rings designed to meet stringent sealing requirements. In this guide, we will delve into the world of Neoprene O-Rings, exploring their unique features, applications, and why NewDealSeals is your trusted source for premium sealing solutions.

What are Neoprene (CR) O-Rings?

Neoprene O-Rings, as the name suggests, are circular sealing rings made from Neoprene rubber. The material of Neoprene O-rings (also polychloroprene) often referred to by the trade name Neoprene. Chloroprene has good resistance to oxygen, ozone, and UV light.

Why Choose Neoprene (CR) O-Rings?

    
  • Exceptional Performance: Neoprene (CR) O-Rings are known for their robust sealing properties, making them ideal for demanding applications in automotive, industrial, and marine sectors.
  • Durability: These O-Rings exhibit outstanding resistance to abrasion, weathering, and environmental factors, ensuring longevity and reliability.
  • Chemical Resistance: Neoprene (CR) O-Rings provide excellent resistance to a variety of chemicals, making them suitable for diverse sealing needs.
  • Versatility: They excel in both high and low-temperature environments, delivering consistent performance across a broad temperature range.
  • Wide Range of Applications: From engine gaskets and machinery seals to marine equipment and more, Neoprene (CR) O-Rings find utility across various industries.

Neoprene O-Rings vs. Natural Rubber O-Rings

Due to the similarity of their structures, natural rubber and chloroprene are generally comparable in their good strength, abrasion resistance, resilience, elongation, and strain crystallisation characteristics. Both also offer a similar low fatigue property, low heat buildup, low temperature flexibility, and high bond-ability. Chloroprene surpasses natural rubber in its resistance to aging, heat, oils, ozone, and solvents. Chloroprene has also gained FDA approval for use in the food and beverage industries.

Neoprene O-Rings performs well in:

  • Mild acids
  • Refrigeration seals
  • Silicone oil & grease
  • Water

    Neoprene O-Rings does not perform well in:

    • Hydrocarbons (aromatic, chlorinated, nitro)
    • Ketones (MEK, acetone)
    • Phosphate ester fluids
    • Strong oxidising acids
