ABS Plastic Fresh Air Pipeline Variable Diameter Connector

Premium ABS material ensures durability, corrosion resistance, and lightweight performance for long-term ventilation use. Precision-engineered tapered design enables seamless airflow transition between different pipe sizes (40mm–150mm).

Smooth inner wall minimizes air turbulence and noise, optimizing ventilation efficiency in HVAC systems, industrial exhausts, or residential fresh air setups. Flanged edges with reinforced ribs prevent deformation under high-pressure conditions.

Universal compatibility with PVC/PP/PE ducts—ideal for warehouses, factories, kitchens, and greenhouse ventilation. No-tool snap-fit installation saves 50% assembly time compared to traditional couplers.

Factory-direct pricing with bulk discounts for contractors and wholesalers. Certified RoHS compliant for safe indoor/outdoor use.
