Hollow O-ring Replacements

Hollow O-Ring Replacements are designed as a practical and cost-effective alternative to standard solid O-rings in applications that require low closure force and reliable static sealing. By replacing the solid cross-section with a hollow elastomer core, these O-rings compress more easily while maintaining material hardness, ensuring a tight seal even in assemblies with large tolerance variations or limited compressive force.

These hollow replacements provide excellent compression set resistance, long-term durability, and consistent performance over time. Their lightweight, hollow design reduces assembly force and minimizes stress on delicate components, making them ideal for enclosures, lids, doors, and other static sealing applications.

Hollow O-Rings operate similarly to traditional O-rings: an elastic ring is compressed between two surfaces to fill the gap, creating a tight seal. The hollow core reduces the force required to achieve the seal, making it easier to assemble without overstressing components. When the ring is compressed in a groove, the hollow section deforms to accommodate the gap, maintaining zero clearance and preventing leakage. Compared to solid O-rings, hollow O-rings provide equivalent sealing performance with significantly less closing force and improved tolerance compensation.

Hollow Spliced O-Rings are ideal for :

 

Applications where low closing force is required.

Rough or uneven surface sealing.

• Automotive components and enclosures.
• Electronic equipment transit cases.
• Handheld electronics and communication devices.
• Low-pressure static sealing in enclosures.
• Outdoor electronics and communication enclosures.
• Power generation and semiconductor applications.

Suitable for

• Low pressure static applications.
• Applications where low closing force is required.
• Applications with rough or uneven surface finishes.
• Environments requiring chemical or abrasion resistance provided by PTFE coating.

Not suitable for

• High pressure applications.
• Dynamic or high-speed motion applications.
• Situations where extreme elasticity is required under repeated cycling.
