Product Overview
Brass 45 degree street elbow, 1/4 inch male NPT to 1/4 inch female NPT. Midland part 28231.
A street elbow has one male end and one female end, so it turns a corner without needing a separate nipple. On a wand or tool where space is tight, that saves both length and a potential leak point.
This is a pressure-rated fitting — 1200 PSI and 121 degrees C — so unlike the hose barbs in this range it belongs on a solution line.
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.

Frequently Asked Questions
What is a street elbow?
An elbow with one male and one female end, so it screws straight into a port without an intervening nipple.
Why 45 degrees rather than the other one?
45 degrees eases a line around an obstruction without the flow loss of a hard corner. 90 degrees is for tight turns where there is no room to sweep.
Can I use it on a pressurised line?
Yes — 1200 PSI rated. That is a real difference from the hose barbs in this range.
Thread sealant or tape?
Either, on the male thread only. Keep it off the first thread so it cannot shed into the line and block a jet.

What We See in the Field
With brass fittings, forcing another turn can distort threads or crack the component you're screwing into. Use the correct sealant for the thread and pressure service and remake the joint if orientation is wrong instead of simply leaning harder on the spanner.
