Blichman Beer Gun & John Guest connections

[mosquat]

hi all,

can anyone let me know which JG connection I need to purchase to connect my beer gun up to my Co2 please? As previously advised on this forum I will be getting a JG tee but the threaded connection to the co2 hose is proving to be a bit of an issue.

I just purchased the 3/8 tube to 1/4 threaded BSPT connection but the thread is too big....so am now thinking it should be 3/8 tube to 1/8 NPT connection:

Any help much appreciated

the wiki page for bsp pipe thread sizes contains a useful chart detailing the thread diameter s in mm https://en.wikipedia.org/wiki/British_S ... read_sizes
major diameter= outside ridge of the thread diameter, minor diameter = inside the groove dameter
for threads below iirc the 1 1/2" size bsp and ntp threads are very compatible,

a 1/4" bsp/ntp thread is about 1/2" in diameter

Just got an 3/8 OD x 1/8 NPT from ebay, can confirm for others that this is the way to go.
