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

• Chlorobutyl extends to outside flange diameter
• Durable coating resists weathering and oxidation

Optional Configurations

• Multiple arch for higher movements
• Filled arch to eliminate media buildup
• Oversized arch for higher movements
• Concentric and eccentric tapers to connect piping of unequal diameter
• Custom Drilling – ANSI, DIN, AWWA, BS, JIS, and special drilling patterns available on request
• Extended face-to-face
• Accommodate misalignment: lateral, angular, and torsional offsets
