Waterproof Gasket Component – Electrical Equipment Manufacturing

Component Specifications

Definition

A specialized sealing component designed for LED underground lighting systems that creates a watertight barrier between mating surfaces, preventing water ingress, dust penetration, and environmental contamination while maintaining electrical insulation and thermal management properties.

Working Principle

Works through compression between mating surfaces to fill microscopic irregularities, creating a continuous barrier that blocks fluid and particle migration via elastic deformation and material memory properties.

Materials

EPDM rubber (Ethylene Propylene Diene Monomer) with Shore A hardness 60-70, temperature range -40°C to +120°C, UV stabilized, ozone resistant, with optional fiber reinforcement for compression set resistance.

Technical Parameters

Thickness 2.0±0.2mm
Compression Set <20% after 24h at 100°C
Compression Force 15-25 N/cm
Temperature Range -40°C to +120°C
Waterproof Rating IP68
Operating Pressure 0-2 bar
Dielectric Strength >15 kV/mm

Standards

ISO 3601-1, DIN 3770, ASTM D2000

Frequently Asked Questions

What is the expected service life of a waterproof gasket for LED underground lights?

Properly installed EPDM gaskets typically last 5-10 years in underground applications, depending on environmental conditions, compression maintenance, and UV exposure levels.

How do I determine the correct compression for installation?

Achieve 15-25% compression of original thickness, typically 0.3-0.5mm deflection, using calibrated torque values on fasteners (usually 2.5-3.5 Nm for M6 bolts).

Can these gaskets be reused after disassembly?

Not recommended for critical applications as compression set reduces sealing effectiveness; always inspect for permanent deformation, cracks, or material degradation before reuse.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
