Welcome to the Bunnings Workshop community. Thank you for joining us and sharing your question about pipe threads.
Bunnings carries a number of Galvanised Pipes in different sizes. The majority of plumbing fittings in the store are all based on BSP thread form which stands for British Standard Pipe and is common in Australia. The pipe sizes are all based on the metric system. If you need advice or information about your project, we are more than happy to assist. Any updates you would like to share would be much appreciated.
