Style 204 Narrow Arch Expansion Joint

Style 204 Narrow Arch Expansion Joint

Expansion Joints » Style 204 Narrow Arch Expansion Joint

The Style 204 family of spool-type expansion joints are manufactured with the industry standard narrow arch design. This style is intended to be used in dynamic conditions where both pressure and vacuum concerns are present. 2D and 3D Cad Drawings available upon request for your specific requirements. Call Munaco for Details.

FEATURES AND BENEFITS

CONFIGURATIONS

 

  • Standard Design
  • Tube
  • Chlorobutyl resists cracking due to high temperatures, weathering, oxidation, and chemicals
  • Abrupt arch configuration provides maximum movement and maximum pressure and vacuum resistance
  • Seamless tube creates a positive flange seal without gaskets
  • Body
  • Chlorobutyl/polyester construction with welded, treated metal body rings for dimensional stability
  • Cover
  • A homogeneous layer of chlorobutyl fully extends to the outside edge of the flange
  • A durable exterior coating futher protects the expansion joint from the effects of weathering and oxidation
 

Vacuum Rating (29.9 In. Hg (750mm Hg.)

> Full vacuum rating for all sizes and face to face
> Style 204EVS available for continuous full vacuum service
