3/4"X1" MPT X Insert Adapter

 Lifegard "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. Threaded Bulkhead Fittings are equipped with female threads and come with the bulkhead fitting, gasket and nut (Teflon tape required). Bulkhead Kits include a bulkhead fitting with female slip fittings (socket), a slip strainer and a 90 degree slip by insert fitting for attaching vinyl hose to the bulkhead (PVC cement required). Bulkhead sizes are �" , �" and 1" and the required hole that needs to be drilled is 1 1/8" , 1 �", 1 �" respectively.
