Threads utilized on HOKE Precision Instrument Pipe Fittings are National Pipe Taper (NPT) which exceed the requirements of ANSI B1.20.1.
Pressure Ratings for temperatures up to 100°F are identified for each individual pipe fitting in the dimensional data charts.
Temperatures noted below apply to basic fitting capabilities. In all cases consideration must also be given to the type of thread sealant used. For example, teflon tape has a maximum temperature rating of 450°F.
