Anyone know what the true OD of a 1/4 MPT and a 1/8 MPT fitting will be?
I'm replacing a CO2 solenoid and needle valve and I'm a bit unsure what size. Looks like most solenoids are 1/8". I have a fitting off my CO2 reg that is 1/8 ID and 3/8" OD.
from Marine depot: Fits most CO2 Regulator Kits on the market. Inlet - Male Threaded NPT 1/8" (measures 1/4" OD physically)
