Product Overview
Brass reducing hex nipple, 3/4 inch male to 1/2 inch male pipe thread. It steps a line down in size between two female ports without needing a separate bush.
Thread Standard — Read This If You Are Mixing Brands
These are American-pattern fittings and the threads are NPT, not BSP. On the parts where the manufacturer states a form it is NPT or NPTF (Dryseal), which is dimensionally NPT with a modified crest and root so it seals metal to metal.
NPT and BSP are close enough to catch people out. NPT is a 60 degree thread form; BSP is 55 degrees. At 1/4 inch and 3/8 inch, NPT is 18 threads per inch and BSP is 19. An NPT male will wind several turns into a BSP female and feel tight — then leak under pressure, because only a thread flank or two is actually bearing.
That matters here more than it does on a garden tap. A leak on a solution line is hot water at pressure. If you are adapting to anything BSP, use a proper adaptor rather than forcing the two together.
Not Published
The manufacturer does not publish a pressure or temperature rating for this part. Other hex nipples in the same family are rated to 1200 PSI and 121 degrees C, but we are not going to transfer a rating across part numbers on a pressure fitting. If you are working to a limit, contact us and we will request it from the supplier.

Frequently Asked Questions
Is this the same as a bush?
It does the same job in the opposite direction. A reducing nipple has two male ends for joining two female ports; a bush has a male and a female end.
What pressure is it good for?
Not published. Related nipples in this family are 1200 PSI rated, but we will not claim that for this part without confirmation.
Is the thread NPT?
These are American-pattern fittings and NPT is the expectation across the range. See the note above before mixing with BSP.

What We See in the Field
A common fitting mistake is choosing by what looks close instead of confirming hose size, thread size and thread type. Brass will often start into the wrong female thread far enough to convince you it fits, then damage both parts when it's tightened.
