Silicone Rubber Gaskets Provide Long Service Life for LED Lighting

LED Lighting Gaskets

LED Lighting Gaskets

Properly specified LED gaskets provide long term weather protection extending the life and performance of LED lighting and solid state lighting. Outdoor, wet location fixtures may be rated for UL 1598, IP65 or NEMA 4 (protected from high pressure water jets). Gaskets and seals must have excellent compression set characteristics along with high, long term resistance to stress relaxation to effectively seal out the ingress of dust and water over time.

Some LED lighting enclosures can be adequately protected using gasket tapes – silicone sponge and silicone foam gasketing slit into rolls with adhesive backings.

Three closed cell silicone sponge products and three silicone foam products are available in slit-to-width gasket tape rolls, slit from pre-laminated master rolls to support rapid response.
