50mm HKS wastegate - Thread Pitch
><
I can't seem to find a fitting for the damn wg. Where did you guys fine the correct fitting for the wg to hook up a vac line?
It's looks finer than a 1/8 NPT.

You would think they could provide a banjo bolt and nipple like Tial or something for the amount of money you pay..........

Who carries BSP fittings? Let me guess,HKS where you have to take it bent over.

Right, which is known as 1/8 BSP
other abbreviations BSPT, PT, KR R or Rc
In other regions known as
ISO 7-1
DIN 2999
BS21 (BS EN 10227-1)
JIS B0203
28 threads per inch
.38" OD
55 deg thread angle
rounded roots/crests
taper 3/4" per foot or 1 in 16 on the diameter
I found out all that looking for adapters for my Greddy temp gauge sender- Swagelok catalogue kept rererring to 1/8 NPT and 1/8 ISO. I was pretty sure ISO was same as BSP and sure enough the above stats matched up.

I just man threaded it with the aid of a wrench.
Tapping not required
Enough threads per inch
.38"ish OD
~55 deg thread angle
rounded threads
tapered large enough per foot or 1 in 16 on the diameter
works for me LOL

No it wasn't to stroke my "ego", for that I put up pics of my car
It was good factual info because I see how many people on here don't know the diffrence between 1/8 NPT American and 1/8 BSP as I myself did not before I bought my HKS GT 60mm WG and put AN lines to it.
If searching for an adapter or hose end w/ the right thread pitch ALL that info is useful because so many sites only list SOME of the specs and you have to decide if it is what you are looking for- as with my example of the Swagelok catalogue refering to is only as 1/8" ISO.
I wrote down the specs in my project notebook for reference...
