GUARDIAN^® 200

• High-density FEP liner reduces permeation and offers optimal chemical resistance
• Mechanically bound liner reduces delamination; no glue to be vulnerable to chemical attack
• High pressure and vacuum resistance ensures suitability for broad range of applications
• Available with GYLON^® 3545 gasket face for raised face flange connections. A gasket is not required on full face flange. FEP is compressible to achieve seal.

• Size:

• Pressure and Vacuum Rating:

• Vacuum Rating (All sizes and pressure classes):
  • Full vacuum / 29.9 in Hg / 750 mm Hg

Standard Design

• Tube – Seamless FEP lining extends to the outer edge of the flange; completely fused to the joint body. Abrupt arch design used for maximum movement capabilities.  A gasket is not required on full face flange. FEP is compressible to achieve seal.
• Body – Chlorobutyl/polyester construction with welded, treated metal body rings for dimensional stability
• Cover – Homogeneous layer of chlorobutyl elastomer is standard. Elastomer extends to the outside diameter of the flange

Optional Configurations

• Special Designs- Non-standard face-to-face dimensions
• Non-standard drill patterns- Blind flanges (no drilling) 
• Available with GYLON^® 3545 gasket face for raised face flange connections
