ASME B16.20/16.5 2" OD 4.5MM THICK CLASS 600# SS316 SPIRAL WOUND GASKET

Advantages

• Outstanding sealing characteristics at a wide range of seating stress levels. Helps compensate for wide swings in temperature and pressure.
• Very forgiving of inconsistent bolt torqueing or installation error. Applicable to almost all types of flanges regardless of bolt load available.
• The working thickness of sealing layers is extremely small reducing fugitive emissions.
• Low seating stresses required reduce flange damage and gasket removal problems.
• The gasket cores are reusable reducing cost and eliminating gasket disposal problems.
• Offers extreme temperature and chemical resistance because of the variety of materials available.
• Extremely high pressure are easily sealed with confidence.
