Lifegard Aquatics Slip Bulkhead with Nut and Gasket. Lifegard Slip Bulkhead "heavy wall" bulkheads are constructed of the highest impact resistant PVC. It eliminates the possibility of finding hidden cracks when filling the aquarium. Stock colors are "jet black" and "bright blue" to match acrylic tank backgrounds. Bulkhead fittings are used for attaching filters, pumps, protein skimmers and other devices to either an acrylic aquarium or reservoir using standard PVC fittings.
To install, drill the appropriate size hole where you want the bulkhead located and install the bulkhead with the gasket between the tank and the bulkhead flange. Hand-tighten only, then one quarter turn to seal.
Bulkheads have slip fittings on both ends.
