Ordering the right length of pipe for your project doesn’t have to be a guessing game. Try to allow an extra 50% of the thread length for couplers and other fittings, and you’ll be well on your way to success.
When ordering pipe lengths, you can allow aproximate extra length to protrude into couplers and other fittings. This is not an exact process however but a rule of thumb is around 50% of the thread length.
There are flanges that take more thread length and some parts will accept a tighter fixing to allow threads to close up.
Theae are all male tapered and female non tapered so the fitting will get tighter the more you rotate into the fitting.
The only way to make items with absolute accuracy is to test fit each component.
We will attempt here to provide thread lengths for each diameter of plumbing pipe we offer.
Half inch threads: 16mm
Three Quater inch threads: 18mm
One inch threads: 20mm
