Low closure force hollow seals
Low Closure Force Hollow Seals
Low closure force hollow seals are engineered to deliver effective sealing with minimal compression force, making them ideal for lightweight assemblies, enclosures, and applications where reducing bolt load is critical.
These seals feature a hollow cross-section design, allowing them to compress easily while maintaining reliable sealing performance across a wide range of industries.
What Are Low Closure Force Hollow Seals?
Low closure force hollow seals are elastomer sealing solutions designed to reduce the amount of force required to achieve an effective seal.
Their hollow profile allows for:
- Easier compression
- Reduced clamping force
- Improved sealing efficiency
This makes them particularly suitable for enclosures, housings, and lightweight structures where traditional solid seals would require excessive load.
Key Benefits of Hollow Seals
Reduced Bolt Load & Clamping Force
Hollow seals significantly reduce the force needed to compress the seal, lowering bolt load requirements and flange stress.
Lightweight Sealing Solution
Ideal for applications where weight reduction is important, such as aerospace and electronics.
Improved Sealing Performance
Maintains reliable sealing even under low compression conditions.
Cost & Design Efficiency
Allows for:
- Lighter components
- Reduced hardware requirements
- Simplified assembly
Applications of Low Closure Force Seals
Low closure force hollow seals are widely used in:
- Telecommunications equipment
- Electronics and semiconductor systems
- Aerospace and defence applications
- Automotive components
- General industrial enclosures
These seals are particularly effective in sealed enclosures, cabinets, and boxes, where consistent sealing must be achieved without excessive force.
Design & Construction
Low closure force hollow seals are typically manufactured as:
- Spliced hollow rings for custom sizes
- Continuous profiles for uniform sealing
- Elastomer-based materials suited to specific environments
Their design ensures:
- Consistent compression
- Long-term durability
- Reliable sealing under varying conditions
Why Choose Low Closure Force Hollow Seals?
Compared to traditional solid seals, hollow seals offer:
- Lower installation force
- Reduced structural stress
- Better suitability for delicate or lightweight assemblies
- Enhanced performance in low-load sealing applications
- They are an ideal solution when minimising compression force is as important as sealing performance.

FAQ's
1. What are low closure force hollow seals?
Low closure force hollow seals are elastomer seals with a hollow internal profile, designed to compress easily and create an effective seal with minimal force. They are ideal for lightweight assemblies and enclosures.
2. When should hollow seals be used instead of solid seals?
Hollow seals should be used when reducing clamping force or bolt load is important, such as in delicate housings, lightweight structures, or applications where excessive compression could cause damage.
3. How do hollow seals reduce bolt load?
The hollow cross-section allows the seal to compress more easily than solid seals, meaning less force is required to achieve a tight seal, which reduces overall bolt load and structural stress.
4. What applications use low closure force seals?
These seals are commonly used in electronics enclosures, telecommunications equipment, aerospace components, and industrial housings, where consistent sealing is needed without high compression force.
5. What materials are used for hollow seals?
Low closure force hollow seals are typically made from elastomer materials such as silicone, EPDM, or neoprene, selected based on temperature, environmental exposure, and performance requirements.
