Pressure Ratings
All ratings comply with calculations in accordance with ANSI Code for Pressure Piping B31.3,Process Piping.
Working pressure ratings determined at room temperature with gasket materials shown.
Plating
Female nuts are plated with silver. Chemical precesses used for cleaning, electropolishing,and passivation may remove plating. Damaged or removed plating may cause thread galling, damage of fitting components and prevention of a proper seal.
Packing
All metal seal fittings are double packaged in clean room. (Class 10 and 1000)
Sealing part is protected with a plastic cap(yellow cap for BA, blue cap for EP)
Feature
Assembly
Cleaning
Passivation in Nitric environment.
Ultra-sonic cleaning with minimum 18MΩ of D.I water after passivation.
Testing
Helium leak rate of 1 x 10-9 Torr. ℓ /s
