Stack of O-Ring Products

Create tight, long-lasting, and leak-proof seals with O-ring products from Ace Seal. Our superior and versatile O-rings offer increased high-sealing capabilities and are utilized across a wide variety of industries for numerous applications. O-ring products are available in a wide range of materials, allowing for customization for specific conditions. They are adaptable to both dynamic and static applications and offer durability in low- or high-stress environments.

O-ring seals from Ace Seal are mechanical gaskets featuring a circular cross-section and crafted from elastomer materials. These seals are employed in pumps, cylinders, and various fluid applications to form leak-proof connections between two components. Positioned within a machined or molded groove on a part’s surface, the O-ring undergoes compression and cross-sectional deformation when the two parts are assembled, creating a tight seal.

Ace Seal is your reliable provider of rubber O-ring options for numerous diverse applications. With an emphasis on improved productivity and reduced costs, we are your trusted partner for all your sealing needs.

Advantages & Features of Rubber O-Rings

O-ring products can be used across a broad range of operating temperatures and in low- or high-pressure applications. There are several advantages to using O-rings, including:

  • Lightweight
  • Compact design
  • Easy to install and maintain
  • Cost-effective
  • Reusable (depending on material and application)

When appropriately used, O-rings do not require adjusting and have a long usable life. Factors that contribute to O-ring failure include improper installation, inadequate lubrication, abrasion, using the incorrect size or elastomer, or allowing for too much or too little compression in the gland design. You can prevent these and other issues by selecting the right size, durometer, and compatible material with your application temperature, fluid or chemical type, and sealing pressure.
