Features

◎ The hardened threads with smooth surface finishing avoid galling and help to extend the fitting service life
◎ Radius junction design for elbows provides smooth flow path
◎ Every fitting is marked with size, material and heat number

Cautions:

◎ Do not loosen or tighten fittings when system is pressurized.
◎ Always use proper thread sealants on tapered pipe threads.
◎ Confirm the sealing type when choosing the straight threads, and make sure the construction of the matching threads comply with the sealing type.

◎ Working Pressure:

1. Catalog working pressures shown are based on ANSI/ASME B31.3 at ambient temperature, to determine working pressures in accordance with ANSI/ASME B31.1 multiply catalog working pressures shown by the factor Material, Carbon steel Factor 0.85, Brass Factor 1.0
2. Use the allowable working pressure at ambient temperature to multiply the elevated temperature factors to get the working pressure at elevated temperature. To know the elevated temperature factor, please see F-14.
3. For technical information of NPT thread and ISO tapered thread, please see page A-06 and A-07 our catalogue.

4. for High pressure please use High Pressure Pipe Fittings
5. Different maximum pressure between Tube fitting and Pipe Fitting. for tube fitting maximum pressure is depend of tube specification,
