How do I measure my aquarium bulkhead?

You need to measure the OD of the PVC pipe going into the bulkhead, and take the bulkhead off and measure the hole in the glass. Once you measure the pipe OD, you need to reference a pipe chart to determine the nominal pipe size. For example, 1″ pipe has a 1.315″ diameter measurement, 1.5″ pipe is 1.9″ OD, and so on.

What is a bulkhead in piping?

A bulkhead fitting allows piping connections to be made to a tank. A hole is cut in the tank into which the fitting body is inserted. A locknut threads onto the body to hold it in place. Bulkhead should be hand tightened and then another 1/4 to 1/2 turn. Over tightening may distort the gasket and cause leaks.

What does a bulkhead do?

Bulkheads are normally smaller than seawalls, as often their primary function is to retain fill at locations with only limited wave action, and not to resist coastal erosion. A bulkhead must, of course, be designed to resist erosion caused by the mild to moderate wave climate at a specific site.

What’s the pressure on schedule 80 PVC bulkheads?

Stocked bulkheads come with left hand threads that makes installation easier. They are engineered with left hand buttress threads that protect the bulkhead fitting against blowout. Schedule 80 PVC bulkheads can handle temperatures up to 140 degrees F (60˚C). They are pressure rated to 150 PSI (10.3 bar) max at 70 degrees F (21˚C).

What kind of fittings are CPVC bulkheads made for?

CPVC Bulkheads are durable schedule 80 CPVC fittings that are made for high-pressure tank applications with more aggressive chemicals.
