Fresh Air System Flange Fast Connector – Premium PE & Silicone Duct Solution
High-grade PE material ensures durability and airtight sealing for long-term HVAC performance. Flexible silicone sleeve (110mm/160mm) absorbs vibrations, reducing noise in residential or commercial ventilation systems. Precision-engineered flange design enables rapid installation without tools, compatible with most standard ductwork. Reinforced inner lining resists deformation under extreme pressure (up to 500Pa). Ideal for connecting exhaust fans, air handlers, or industrial ducts in kitchens, bathrooms, and factories. UV-resistant silicone prevents cracking in outdoor applications.
