Tri-Clamp Unitized Gasket – PTFE (Teflon®) x EPDM
Internal Un-Flanged Design
PTFE x EPDM Unitized Gaskets combine the chemical resistance of PTFE with the sealing memory of an EPDM elastomer. This design provides improved sealing performance over standard elastomer gaskets and better adaptability than PTFE-only gaskets in applications where slight ferrule misalignment exists.
Construction
- PTFE sealing surface bonded to EPDM core
- One-piece unitized design
- Internal, un-flanged configuration
This construction reduces component movement and improves gasket stability during installation and operation.
Performance
- Resistant to a broad range of chemicals (PTFE contact surface)
- EPDM core provides recovery and sealing force
- Performs better than solid PTFE under minor misalignment conditions
- Reduces initial creep and cold flow compared to PTFE-only gaskets
Unitized construction delays the onset of creep and cold flow; however, these conditions will still occur over time with PTFE-based materials.
Limitations
- PTFE materials are subject to creep and cold flow under load
- Leakage may occur at pressures below standard clamp ratings
- Not recommended for use with bolted clamp assemblies
Pressure Rating Notice:
The 150 PSI service rating for sanitary clamps does not apply to connections 1” and larger when using PTFE-based gaskets.
This restriction does not apply to ½” and ¾” sizes, where the gasket is fully contained by the ferrule design.
Compliance
- Materials meet FDA 21 CFR 177.2600 requirements
- Suitable for use in systems operating under GMP guidelines
Maintenance
Gaskets should be replaced on a scheduled basis in accordance with GMP practices. Replacement intervals depend on:
- Service conditions
- Pressure and temperature
- Chemical exposure
- Frequency of use
Storage
- Shelf Life: 10 years from cure date
- Store in original packaging
- Keep in clean, dry environment
- Avoid direct sunlight
- Maintain minimum 6 ft distance from electric motors
- Storage temperature: 65°F – 85°F
Summary
PTFE x EPDM Unitized Gaskets are used where chemical resistance is required along with improved sealing performance over standard PTFE gaskets. Proper application, pressure limitations, and routine replacement must be observed due to the inherent characteristics of PTFE materials.
