1 1/2" Slip x Slip Bulkhead

A 1 1/2" Slip x Slip Bulkhead is a plumbing fitting, typically made of PVC or ABS plastic, used to create a watertight connection through a wall or barrier, like an aquarium or sump. It features slip (or socket) connections on both ends, allowing for easy attachment of pipes of the same diameter. These bulkheads are commonly used for drains, overflows, and other plumbing applications in aquariums and similar systems.
