Thread Differences
Trying to get an oil pipe for my oil pressure gauge, but is there any difference between 1/8NPT and 1/8 BSP ?

PassionFord Post Whore!!
a lot really, the thread forms are different aswell, one has 60 degree inc flanks and the other is a whitworth form of 55 degree inc angles. Bsp has the whitworth form of 55 degree angles.
Bsp is a parrallel thread form where the NPT is a tapered form that runs at 1'47" taper
The NPT is 27 tpi where the Bsp is 28 tpi
Unless you meant to say Bspt which is different again
Hope this helps

BSP is "British Standard Pipe Thread"
NPT is "National Pipe Thread" which is American.
You can get parallel and tapered BSP threads.
