Rubber Components for HVAC Equipment, Manufactured in India

EPDM, rated −40 to +140 °C, for its UV and ozone resistance — ozone attack is what ends most outdoor seals and EPDM resists it better than anything else we mix. Silicone to +220 °C where the duty runs hotter. Not nitrile outdoors, whatever its oil resistance — it hardens in sunlight.

Flame-retardant compounds are available on request — neoprene is the family we reach for, and formulated grades can be specified against a flammability rating. Send your standard reference with the enquiry — UL 94, BS 476 or your own OEM specification — and we will confirm what the compound supplier can evidence. We do not hold a flammability listing ourselves.

By static load rating and deflection at that load, plus mounting geometry and durometer. Send the machine mass, the number of mounting points and the running speed — the mount and the mass form a spring-mass system, and isolation only begins above about 1.4 times its natural frequency, which is why a mount that is too stiff for its load does nothing at all.

Yes — we are a volume manufacturer. Margo produces in bulk against OEM schedules rather than in small lots. Minimum run is 10,000 pieces per part number, per compound, and on larger or more complex parts the minimum is quoted against the part, because the economics are set by tooling and cure time rather than by piece count. Existing tooling ships in three to four weeks ex-works Nashik, or two weeks express where we have confirmed capacity; a new part adds the tooling lead time, quoted per part. Prototype within 48 to 72 hours of an approved drawing.

Yes — closed-cell foam for weatherseals and duct liner, open-cell for acoustic lining, and solid profiles where the joint carries load. The choice is driven by the gap to be sealed and the closing force available: foam fills an uneven gap at low force, solid holds a defined compression. Send the gap and the closing force and we will tell you which.

Margo Rubber Products holds ISO 9001:2015, certificate 09111526A, issued by Integral Certification Ltd and valid to 21 February 2027. We are actively upgrading our quality management system to IATF 16949:2016, with certification targeted by the end of 2026, and ISO 14001 and ISO 45001 certification targeted for 2027. Material test reports and batch certificates are issued with every shipment.
