Street Elbow, Brass, 1/2in. (F)NPT x 1/2in. (M)NPT, 90Deg.
◎ 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
◎ Sizes range from 1/16 to 2
◎ Thread Specifications:
Thread Type Specification
NPT ASME B1.20.1, SAE AS71051
ISO Tapered IS0 7-1, BS 21, JIS B0203
ISO Parallel IS0 228, JIS B0202
SAE/MS ASME B1.1, SAE J475
Metric ISO 261
◎ Working Temperature:
For the working temperatures of FITOK pipe fittings, please see A-10.
◎ 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 from the table below.
Carbon steel 0.85
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. To get the installation torque for NPT thread and ISO tapered thread, please see A-6.
◎ Do not loosen or tighten fittings when system is pressurized.
◎ Always use proper thread sealants on tapered pipe threads.
