Bulkheads allow plumbing to flow through your aquarium or sump.

Heavy duty Schedule 80 PVC bulkheads feature some distinct advantages over ABS bulkheads:

O-Rings are 2X as thick as ABS O-Rings

Schedule 80 construction will far outlast ABS

Reliable seams

Flange and nut side are very easy to grip

When measuring for bulkheads, you will need a hole in your tank that is slightly larger (1-3mm) than the "C" measurement for the corresponding bulkhead but no larger than the "A" measurement. (see image)

Example: If you have a 1.75" diameter hole currently in your tank, then you would want to use the 3/4" Sch 80 Bulkhead.

1/2" SCH 80 SxT Bulkhead Dimensions (see diagram)

A - 51mm/2"

B - 70mm/2.75"

C - 32mm/1.25"
