HVAC Components That Actually Last

For HVAC systems, facing harsh conditions every day is inevitable. Blazing heat in summer, subzero temperatures in winter, constant vibration, condensation, and UV exposure on rooftop units. Ordinary rubber and plastic parts crack, harden, or flatten within months. Then the air leaks start. The noise complaints roll in. The service requirement demand starts to happen frequently. ARCADIAN makes HVAC components differently. We start with the real operating conditions.

Our rubber gaskets for HVAC seal cabinet panels and access doors without crushing or taking a permanent set. For ductwork and plenums, we manufacture custom air sealing profiles that conform to irregular surfaces where foam tapes fail. We also make silicone insulation that withstands radiant heat without becoming brittle.

Whether it is isolating a rooftop compressor or guiding airflow through a tight plastic assembly, ARCADIAN delivers parts that can retain their function for a very long time. No more callbacks for failed seals.

Why Arcadian

Why ARCADIAN? Your Silent Partner in System Reliability

HVAC contractors and OEMs choose ARCADIAN for one reason: our parts stop the small failures that turn into expensive service calls. We do not just mold and extrude. We engineer for the real world—condensation, thermal cycling, and years of vibration. Our Rubber Extrusion Services generate continuous air sealing profiles with exact cross-sections and smooth finishes.

Rubber Molding Services gives you complex geometries in high-durability compounds. Silicone Molding Services handles the high-heat zones that destroy ordinary elastomers. We ask about your mounting method, your pressure differentials, and your maintenance access before we design a single tool. That is how we, at ARCADIAN, deliver precision gaskets for HVAC that seal on day one and stay sealed five years later.

Why Choose Us

Engineered for the Mechanical Room and the Rooftop

HVAC applications are not all the same. A chilled water line seal sees condensation and thermal contraction. A rooftop curb gasket faces UV, ozone, and 100°F temperature swings. A fan mounting pad needs rubber vibration mounts that isolate without loosening. ARCADIAN compounds each part for its specific working condition.

We make plastic air duct components that resist warping and hold their shape under negative pressure. Our Silicone Seals & Gaskets handle the high-temperature end of the system—think flue exhausts and heat exchanger access panels.

Here is what we engineer into every HVAC component:

UV-resistant compounds for rooftop and outdoor exposure
Low compression set for flanges that get torqued once
Tear-resistant profiles for sliding installations

Our precision vibration mounts are not standard components. We calculate durometer and shape to match your equipment's weight and operating frequency. Too soft, and the mount bottoms out. Too hard, and vibration transmits straight into the building structure. ARCADIAN gets it right. And when you need rubber gaskets & seals for AHU access doors or filter frames, we deliver exact-fit profiles that do not require caulk or glue.

Everyday Places We Solve HVAC Problems

From single-family residential to industrial cleanrooms, ARCADIAN components are holding pressure, killing noise, and managing thermal breaks. Our precision gaskets for HVAC seal economizer hoods, fan coil unit panels, and rooftop curb adapters. Air sealing profiles from our Rubber Extrusion Services line the edges of VAV box access doors and duct access panels.

Silicone insulation gaskets protect control cabinets mounted near heat exchangers. Rubber vibration mounts isolate condensing units, air handling units, and chiller compressors from structural steel. Plastic air duct parts include custom branch fittings, turning vanes, and access port plugs. Finally, our Silicone Seals & Gaskets are specified for high-temp flue connections and heat recovery ventilator bypass doors.

Here are six common applications we solve daily:

Rooftop unit curb gaskets (weatherproof, UV resistant)
Chiller line vibration isolation pads
AHU access door perimeter seals
Ductwork turning vane end caps (plastic air duct parts)
Exhaust flue collector box gaskets (high-temp silicone)
Fan housing mounting isolators (rubber vibration mounts)

We also make rubber gaskets & seals for filter rails, coil access panels, and mixing box dampers. Every extrusion, molded part, and silicone profile from ARCADIAN shares one trait: it fits correctly right from the first time. No trimming. No stretch-to-fit. No field modification. Our customers tell us that alone cuts their installation labor by hours per unit. That is not a promise. That is how we have completed hundreds of HVAC projects across a wide range of industries.

Stop chasing air leaks and vibration complaints. Send ARCADIAN your HVAC application—rooftop unit, air handler, ductwork, or chiller. We will recommend the right compound, profile, and molding or extrusion method. Request a quote or a sample profile today. Let us design parts that outlast your warranty period.

Frequently Asked Questions

Find answers to the most common questions about our services and manufacturing process.

We stock common profiles for next-day shipping. For custom orders, first articles typically ship in 10-12 business days.

Either way, our rubber molding services include both. We can supply plain pads or bonded metal-backed mounts with pre-drilled holes and studs.

Send us a 6-inch sample or a detailed drawing. We reverse-engineer and reproduce it exactly.

We have a very low minimum order quantity. We prototype single pieces and scale to thousands. Same tooling, same quality.
