Key Features
- Excellent elastic seal: EPDM material conforms tightly to pipe outer wall under compression for reliable sealing.
- Aging resistance: resists ozone and UV, remains flexible without hardening or cracking over long-term use.
- Easy installation: pre-installed in fitting socket groove, no additional sealant required.
- Precise dimensions: manufactured to standard tolerances for optimal fit with fittings and pipes.
Manufacturing Process
Manufactured by compression or injection molding. EPDM compound is vulcanized and formed with precise control of cross-sectional shape and dimensions.
Critical Process Parameters
- Control of compound formulation and vulcanization process to meet physical properties.
- Precise control of cross-section dimensions and inner diameter tolerance.
- Testing of hardness, tensile strength, and compression set.
Raw Material Characteristics
- Material Composition: Ethylene Propylene Diene Monomer (EPDM), compliant with potable water standards.
- Material Properties: Excellent ozone and aging resistance. Good elasticity and compression recovery. Wide operating temperature range, -30°C to +80°C. Complies with potable water hygiene standards.
Typical Applications
- Sealing for UPVC rubber ring joint fittings.
- Flexible joint sealing in water supply piping systems.
- Pipe connections requiring quick installation.
Application Scenarios
- Sealing for all UPVC rubber ring joint fittings.
