help Chesterton 450 FAQ
Is Chesterton 450 actually a mechanical seal?
A.W. Chesterton 450 is identified in manufacturer material as a synthetic fiber sheet gasket rather than a rotating mechanical seal. It is intended for general service in water, gas, brine, and steam applications.
What pressure and temperature can Chesterton 450 handle?
The published limits are up to 25 bar and 200 degrees C. Those limits make it a low-temperature general-service gasket, not a high-temperature seal for every rotating-equipment application.
What is Chesterton 450 used to seal?
The product is used for stationary flange gasketing in services such as water, gas, brine, and steam. Chesterton lists it as a non-asbestos synthetic fiber sheet available in several thicknesses.
Is Chesterton 450 suitable for aggressive chemical service?
It is not a universal chemical gasket, because the manufacturer excludes chlorinated hydrocarbons, aromatic compounds, and ester ketones. Material compatibility should be checked before specifying it for chemical equipment.
