1.5" Bulkhead Fittings

Bulkheads are used to attach plumbing to aquariums and sumps to create a leak free way to move water.  

Bulkheads come in different sizes and different ways to connect plumbing.  you can choose from:

Slip x Slip - both the inside and outside of the bulkhead will require a solvent to permanently bond the plumbing to the pipe. 

Thread x Thread - both the inside and outside will use a male NPT threaded fitting 

Slip x Thread - The part of the bulkhead on the inside of the tank uses a slip fitting (requires solvent) and the outside requires a male NPT fitting 

Thread x Slip - The part of the bulkhead on the inside of the tank uses a threaded fitting (for make NPT fittings) and the outside of the tank is a slip fitting (requires solvent)
