1/8 NPT can be FORCED into 1/8BPT, but it is not the same.
I just ordered some BPT fittings from Hose and Fitting Supply (Parker Store) in West Sac. Took over three weeks to get them, on a rush shipment! <IMG SRC="smilies/frown.gif" border="0">
I ordered a fitting from Central Four Wheel Drive, and they had it in two days!!!
They also kicked down fifteen feet of tubing for free!! <IMG SRC="smilies/biggrin.gif" border="0">
