Wide Arch Expansion Joint

Super-Flex Styles 1000, 1100 and 1200

The Superflex 1000 provides double arch movements utilizing a single low profile wide arch. Manufactured utilizing tire industry technology the style 1000has been designed to provide greater strength and pressure capabilities. The construction combines woven polyester fabric and reinforcedSuperflex Style 1000
with wire to create a product with superior performance characteristics.

The wide self-flushing arch provides more movement than a traditional spool type joint. When built with a filled arch for smooth bore service, (such as slurry applications) the movements are one half of the single open arch spool type joints. The double reinforced construction gives longer life expectancy and is also available in a full range of elastomers to enable multi-purpose applications.

The primary difference between the Style 1000 and Style 1100 is in the manufacturing process.

The 1000 is hand-wrapped to allow for design variations including offsets, non-standard face to face dimensions, multi-arch configurations and special flanges or drillings while still offering wide arch movement.

The Style 1000 is available in these Elastomers and Constructions:
  • Clorobutyl
  • EPDM
  • Gum
  • Hypalon
  • Neoprene
  • Nitrile
  • SBR
  • Silicone
  • Viton® Flourel®
  • Multi-Arch
  • Offset
  • Special ends
  • Alternative drilling
Optional liners and covers are available

Superflex Style 1100 Expansion Joint

Unaflex's® 1100 series has been designed to compete with the imports in terms of cost, and out perform the imports with a product that's made in America. The movements and benefits match the Style 1000 (above), if you don't need the customization options of the Style 1000.....the Style 1100 is a value packed expansion joint.

Style 1100The cover has been formulated with an ozone and temperature resistant compound which prevents the Style 1100 from cracking unlike the imports. This new manufacturing technology has provided a product that has excellent performance at competitive price.

Due to the molded construction all face to face dimensions are standard. Engineered to withstand full vacuum and high pressure, (see next page). The Style 1100 is an excellent performer with a super price. Specify Superflex!
