Standard Thread Bulkhead Fitting (1/2 Inch) Standard Thread Bulkhead Fitting (1/2 Inch) is a PVC aquarium bulkhead fitting for creating a sealed plumbing pass-through with a threaded wet-side connection and a slip pipe connection on the outside. It is useful for smaller aquarium returns, drains, reservoirs, sumps, reactors, and custom filtration plumbing. 1/2 Inch Standard Thread Bulkhead for Slip Pipe Plumbing This standard thread style accepts a matching threaded fitting on the tank side while allowing slip pipe connection on the outside. That makes it a practical choice when the inside of the tank or sump needs a threaded strainer, fitting, or adapter, while the outside plumbing is built with glued slip pipe. Standard Thread 1/2 Inch Features 1/2 inch nominal bulkhead fitting for aquarium plumbing. Threaded wet-side connection for matching threaded fittings. Slip pipe connection on the outside for glued plumbing runs. Heavy wall PVC construction for durable installation. Black finish blends well with aquarium backs, sumps, and overflows. Includes gasket and lock nut for installation through a drilled panel.
