常见问题

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.
