Our 4-inch (10.16cm) general aviation waste coupler is expertly engineered for maximum strength and reliability. Say goodbye to spills, leakage, and parts that wear out quickly.
The collar piece is made of polyurethane – making it virtually indestructible. All other components are made of stainless steel and hard anodized aircraft grade aluminum (not plastic or casted metal like other manufacturers). The coupling drain tube is a solid machined aluminum tube with hose barb and stainless steel locking balls – resulting in a long-lasting and non-corrosive coupler.
This coupler is easily serviceable and rebuildable.
