Precision moulded and extruded rubber components — gaskets, profiles, O-rings, grommets, custom parts — supplied to manufacturers across India, by founders with decades of operating depth in rubber and in business.
Compounds, tolerances and finish held to the standard your application demands — not the one that's easy.
To drawing. To spec. Batch after batch, with the same numbers.
What's possible, what isn't, what it costs and when it ships — all stated upfront, in writing.
Promised dates, met. If anything threatens that, you hear about it early — never late.
We treat customers the way the partnership itself is built — for the long term. Relationships measured in years, not orders.
Six categories, custom to your drawing or sample. Across six base polymers — Silicone, EPDM, FKM, NBR, Neoprene, SBR — and the hundreds of compounds we formulate from them.
Complex geometry seals for pressure and temperature cycling.
Custom cross-sections. Any length, constant section.
All major sizes and compounds. Static and dynamic sealing.
Cable and wire sealing for IP67/68 enclosure designs.
Foam profiles and strips at low compression force.
Extruded silicone strips and tapes for sealing, masking and gasketing.
Moulded bushes, mounts and pads that damp shock and noise — rubber-to-metal bonded.
Send drawing, sample or spec. We engineer what you describe.
Silicone is our specialism — but we mould and extrude across the full range, formulating each polymer into the exact compound your part needs. Click any material for properties, strengths and where it fits.
Outstanding weather, ozone, steam and hot-water resistance — built for the outdoors.
View details → // SILICONE (VMQ) specialistWidest temperature range, excellent UV, weather and electrical insulation. Moulded and extruded — our core material.
View details → // NBR (NITRILE)Excellent oil, fuel and abrasion resistance — the workhorse for industrial seals.
View details → // FKM (VITON-TYPE)High-heat with oil, fuel and chemical resistance for the most aggressive duty.
View details → // SBRCost-effective abrasion and impact resistance for general-purpose parts.
View details → // NEOPRENE (CR)A balanced all-rounder — weather, moderate oil and flame resistance in one.
View details →Design, compound, tooling and production, all under one roof. We read the drawing, choose the compound, build the tool and make the part — not parts off a shelf, but the whole chain under one partnership.
Work from your drawing or sample, prototype the part, and prove it before committing to tooling.
Match the compound to the application — Silicone, EPDM, FKM, NBR, CR or SBR — for the chemistry, heat and load it has to take.
Compression moulding and rubber-to-metal bonding — complex parts held to drawing, batch after batch, with the same numbers.
Continuous profiles and channels in custom cross-section — any length, the same section throughout.
Tooling cut to your geometry, not adapted from something close enough.
Replace imported components with locally engineered equivalents — same spec, a shorter supply chain.
Custom rubber seals, gaskets, grommets and profiles for manufacturers across India — from electrical and lighting to automotive, EV, batteries and solar. If the part is hard to source, that is exactly what we make.
Custom seals, gaskets and cable grommets that keep dust and moisture out of electrical enclosures, connectors and assemblies.
Weatherproof silicone gaskets and seals that keep LED fittings and light fixtures sealed, indoors and out.
Insulating moulded and extruded rubber parts for switchgear and power-distribution equipment.
Made-to-drawing rubber components for OEMs — the non-standard part, engineered exactly to your spec.
Sealing gaskets, drain seals and anti-vibration pads that keep HVAC and dehumidifier units quiet and leak-free.
Seals, grommets and anti-vibration mounts for automotive ancillaries and electric-vehicle assemblies.
Vent seals, terminal gaskets and enclosure seals for industrial and automotive battery packs.
Weatherproof gaskets and cable grommets for solar junction boxes, inverters and outdoor enclosures.
Exonel is a new firm — but not new ground. Its founders bring decades of operating experience: one in rubber design and manufacturing, the other in finance and operations. Both pointed at one thing — doing it the right way, for customers who know the difference.


We work across six base polymers — Silicone, EPDM, FKM (Viton-type), NBR (nitrile), Neoprene (CR) and SBR — formulated into hundreds of compounds, and match the right one to the heat, chemicals and load your part will see.
Yes — bespoke work is most of what we do. Send a drawing, a sample, or even a description, and we engineer the moulded or extruded part to match it.
It depends on the part, compound and process. Tell us what you need and we'll confirm the right quantity for your job — just get in touch.
Electrical, lighting, switchgear, HVAC and dehumidifiers, automotive and EV, batteries, and solar and renewables — for manufacturers and OEMs across India, including parts that replace imports.
Absolutely — picking the elastomer and hardness is part of the job. We'll recommend the compound suited to your temperature, chemical and load conditions before any tooling is cut.
Send a drawing, sample or description by email at email@exonel.in or on WhatsApp, and we'll come back with a material recommendation and a quote.
We manufacture in-house in Howrah (Kolkata), West Bengal, and supply rubber components to customers across India.
Exonel Industries manufactures custom silicone rubber components in-house in Howrah (Kolkata), West Bengal — moulded and extruded seals, gaskets, profiles, cords and sponge — supplied to manufacturers across India.
Yes — import substitution is core to what we do. Send the imported part, a sample or a drawing, and we'll work to a locally made equivalent in the right compound.
Silicone (VMQ) typically performs from about −60°C to +200°C — far wider than most rubbers — which is why it suits lighting, electrical and high-heat sealing. Exact grades are matched to the application.
