定义
A precision-engineered sealing component designed specifically for industrial wire harness conduit fittings, creating a watertight and dustproof barrier between mating surfaces. It prevents moisture, dust, chemicals, and other contaminants from entering the conduit system while maintaining electrical insulation and mechanical integrity in harsh industrial environments.
工作原理
Works through elastic deformation and compression between mating surfaces of conduit fittings, creating a continuous sealing barrier. The sealing ring fills microscopic irregularities in surfaces, while maintaining constant contact pressure through its material's memory properties to accommodate thermal expansion, vibration, and mechanical stress.
材料
Typically made from EPDM (ethylene propylene diene monomer) rubber for general applicationssilicone for high-temperature environments (up to 230°C)fluorocarbon (Viton) for chemical resistanceor polyurethane for abrasion resistance. Shore A hardness typically ranges from 50-80 depending on application requirements.
IP Rating
IP67/IP68 compliant
Compression Set
<25% after 24h at 70°C
Pressure Rating
Up to 10 bar
Tensile Strength
>10 MPa
Temperature Range
-40°C to +150°C (standard EPDM)
Dielectric Strength
>15 kV/mm
标准
ISO 3601-1DIN 3771ISO 6194SAE J200

常见问题

What is the difference between a sealing ring and a gasket in conduit fittings?

Sealing rings are typically O-ring or custom profiles that fit into grooves, while gaskets are flat seals placed between flange surfaces. Both serve similar functions but differ in installation method and compression characteristics.

How often should conduit sealing rings be replaced?

Typically every 3-5 years or during scheduled maintenance, but depends on environmental conditions. Signs for replacement include visible cracking, compression set exceeding 30%, or loss of sealing performance.

Can different material sealing rings be used interchangeably?

No, material selection depends on temperature, chemical exposure, and pressure requirements. Using incorrect materials can lead to premature failure and system contamination.
