How To Measure Pipe Thread
All our fittings & valves are measured using NPT. This is a national standard measure. It is NOT the same as measuring your fitting with a ruler.
If you are unsure of what size fitting or valve you need, please download the instruction sheet below. If you order the wrong size, we will accept exchanges but you will be responsible for freight.
