A versatile threaded vent hose coupler that works with both 5 in (130 mm) and 5.9 in (154 mm) duct sizes—perfect for kitchen hoods, air‑conditioning units, hydroponic systems and any appliance with a vent outlet.

- Join two 5 in hoses together
- Join two 5.9 in hoses together
- Mix a 5 in hose with a 5.9 in hose
- Attach a single hose directly to the appliance vent
Made from high‑grade ABS, the ring resists heat and stands up to daily use. The ridged outer rim gives a firm grip for easy clockwise or counter‑clockwise installation, while the threaded design ensures a leak‑free seal.
