[FONT="]Ive owned a Harbor Freight 2 hp, 8 gallon compressor for 3 years. I use it a lot and it works as advertised. Recently, in a fit of clumsiness I broke off the drain valve for the air tank. Well I removed the bloody stump of the valve and figured Id just make a new one. I measured an OD for the thread of 0.516. Well, thats too big for US Unified. Checking NPT pipe sizes ruled those out, but it seemed about right for a metric 13 mm. Trouble is, a metric die in 13 mm seems to be quite rare so I tossed that possibility. [/FONT]
[FONT="]It did seem right for a ¼ British Standard Pipe Parallel (BSPP) so I checked further and found that in that size, there are 19 threads per inch. Whoops, this is getting pretty hairy, because my lathe wont do that pitch (easily). So whats a yank to do? [/FONT]
[FONT="]I could just order the part from HF but I was never too keen on the valve in the first place. Well I found a nifty little adapter that has ¼ NPT on one end and BSPP on the other. With NPT on the outflow I can plumb in a more convenient ball valve.[/FONT]
[FONT="]Im calling this fitting a Trans-Pond-er!. [/FONT]Rof}
