1/4 in. x 1/8 in. FNPT Threaded - Reducing Hex Coupling - 316 Stainless Steel High Pressure Instrumentation Pipe Fitting(PSIG=6,100)

End Connection: Reducing Hex Couplings- Female NPT x Reduced Female NPT Threads

Standard High Pressure Instrumentation Threaded Fittings Features:

• Wrench flat body design allowing standard hex wrench assembly
• Attractive finishes to suit precision equipment.
• Much less-weight design compared to Class 3000 pipe fittings.
• Fine pipe thread construction equals or exceeds the requirement of ASME B1.20.1 to ensure maximum thread engagement.
• Male pipe threads capped for protection from damages.
• Fitting materials available in SS316, Brass and Carbon Steel.

• These Standard Rating Fittings are designed to the requirements of ASME B31.3 process piping code.
• These pipe thread sizes are available 1/8 in. to 1 in. NPT
• Pressure ratings listed are for temperature up to 37°C (100°F)
• Pressure rating is calculated at -28° to 37°C (-20° to 100°F) using allowable stress value of 20,000 PSI for SS316, 10,000psi for Brass, and 20,000 PSI for Carbon Steel as per ASME B31.3 Process Piping Code.
• To determine the working pressure of ASME B31.1 Power Piping Code, multiply the ASME B31.3 rating by 0.94. Brass pressure ratings remain the same.
