Custom Industrial HVAC Material Solutions: Cabinet Sealing, Vibration Isolation, Thermal Insulation & Fire Protection

Wide reference image of die-cut industrial HVAC materials: rooftop-unit door gaskets, compressor vibration isolation pads, duct flange seals, furnace door gaskets, and filter support foam staged in front of packaged HVAC equipment

H-O Products converts EPDM sponge, silicone foam, neoprene sponge, vinyl nitrile, microcellular polyurethane, rebonded elastomer, polyimide foam, inorganic glass and mica fire barriers, aramid and polyimide dielectric films, reticulated filter foam, structural acrylic foam tapes, and UHMW wear surfaces into die-cut door and access-panel gaskets, compressor and fan vibration mounts, duct and cavity insulation, burner and furnace door seals, refrigerant and oil-loop gaskets, panel bonding tapes, and shipping protection for rooftop-unit, packaged-equipment, appliance, and controls makers.

Material grades are referenced by designation (UL 94, ASTM D1056, NEMA/IP framing) per the vendor TDS. Made to your drawing under an ISO 9001:2015 certified quality management system in Winsted, Connecticut.

The Industrial HVAC applications

Where do you need a converted part?

Nine application areas across the vertical, one converter, all made to your drawing under an ISO 9001:2015 quality management system. Dedicated Industrial HVAC pages are being published; until each goes live, its card routes to the closest live page covering the same materials and physics.

Quote request

Get an industrial & HVAC materials quote

Send a drawing, a system-manual page, or a spec section; partial information is welcome. We typically respond within one business day with a material-family recommendation, the vendor technical data sheet behind it, a prototype lead time, and an honest note on anything that needs a listing holder or a sealant maker rather than a converter.

Part & quantity
Typical response in one business day. Typical prototype lead time is 5–10 business days after drawing review, depending on material availability, tooling, and inspection requirements.

Send a drawing, BOM, or a description of the application and what the part must do, and an engineer typically responds within one business day with a material-family direction and the matching page. Material grades are referenced by designation per the vendor TDS; enclosure ratings and system listings belong to the equipment maker. Volumes, install method, and documentation requirements are reviewed at quote.
