 An O-ring
is a donut-shaped elastomeric component used to create a seal at the
interface of two or more joined parts in a system. Its simple yet
effective design makes it an integral sealing solution across a wide
range of industries. We manufacture custom O-rings tailored to meet the
exact specifications of your application.
We produce O-rings of any size, from 2x2 mm up to several meters in
diameter. Materials available for O-rings include rubber (NBR, EPDM,
FKM), silicone, and polyurethane. Minimum Order Quantity: 1 piece.

In fluid-sealing applications, O-rings are designed to fit securely
within specialized grooves machined into mating surfaces. When the
surfaces are joined, the O-ring’s elasticity allows it to
mechanically deform, creating an airtight, leak-proof seal at the
interface. These versatile seals are used in virtually any
fluid-handling system requiring reliable, tightly-sealed connections.
Types of O-Rings & Sealing Rings:
The most common sealing ring profiles include:
• Standard O-Rings: Featuring a classic donut-shaped cross-section
with rounded edges, standard O-rings offer reliable leak protection
across a broad range of general sealing applications. Custom-molded
profiles fill gaps and fit exact hardware geometry.
• Quad-Rings / X-Rings: Quad-rings feature a unique four-lobed
design that reduces friction, prevents spiraling in dynamic
applications, and provides a longer-lasting seal than standard O-rings.
• Square-Cut O-Rings: Square-cut rings feature a square
cross-section that enhances stability and working pressure tolerance,
ensuring a high-performance seal in demanding operating environments.
