Rubber components for solar and renewable energy
Exonel makes the seals that keep solar and renewable-energy equipment dry in the field: junction-box and combiner-box gaskets, inverter enclosure seals, cable grommets designed for IP67/IP68 sealing applications, and mounting pads. Made to drawing in EPDM and silicone for long outdoor service.
Rubber parts for renewable and solar.
Junction-box and combiner-box gaskets
Moulded and sponge gaskets that seal the lid against the box under UV and heat.
Inverter and enclosure seals
Door gaskets and joined frames for inverter and battery enclosures.
Cable grommets
Grommets and strain reliefs for DC and AC cable entries, designed for IP67/IP68 sealing applications.
Mounting pads and washers
Anti-vibration pads and insulating washers for trackers and mounting structures.
Compound follows the conditions.
UV and ozone
Rooftop and field equipment sits in the sun all day. EPDM and silicone resist UV and ozone ageing.
Thermal cycling
Enclosures heat in the day and cool at night. The gasket has to recover every cycle.
Dust and rain
Lid gaskets and cable grommets are designed for IP67/IP68 sealing applications.
Cost at scale
EPDM gives long outdoor life at a sensible cost for high-volume boxes. Silicone where the temperature range demands it.
What to send us
Send the box or enclosure drawing, the gasket groove, the cable diameters for grommets, the target IP rating and the site conditions. We recommend the compound and quote.
Common questions
Which rubber is best for solar junction-box gaskets?
Can your seals help a junction box meet IP67?
Do you supply in volume?
Need solar enclosure gaskets or grommets?
Exonel Industries makes custom moulded and extruded rubber components in Howrah (Kolkata), West Bengal, and supplies manufacturers across India. We work in six base polymers, Silicone, EPDM, FKM, NBR, Neoprene and SBR, formulated into hundreds of compounds. Compounding, tooling and production are done in-house.
