Thread dimensions/size note

Australian BSP thread size names can be confusing. The mm and inch naming system are only nominal conventions, they are not the physical measurements of the thread size. E.g. a common 15mm (1/2") fitting will have an actual external male thread diameter or an internal female thread diameter measurement of 20.995mm (0.825"); 20mm (3/4") fitting likewise will measure 26.441mm (1.041") 

Please refer to our BSP sizing chart provided in the last image in our gallery. Feel free to asks us any questions.

Educational & Interesting Bathroom Reader
Format: Paperback
I bought this for my husband for Christmas given that he loves history. I figured it’d be a hit as a bathroom reader… I was right and it’s become a fixture right next to the toilet paper! He likes that it challenges him to think. Now there’s no need to take his phone into the bathroom!

BCE? No, it is BC!
Format: Paperback
I love history; there is a lot in this book I did not know. It is definitely a challenge and a great way to learn. I took off one star (considered taking off two) because the author uses the non-Christian term of BCE. I HATE seeing that instead of what it really is BC - before Christ! I wonder if he is an atheist.
