Expansion joints for full vacuum grinding applications

Style 404 expansion joints are designed for full vacuum grinding applications. The tube material is a proprietary polyurethane formulation. Style 404 is available in single, multiple, or filled arch designs. It can connect pipe flanges concentrically or eccentrically to connect pipes of different diameters. Regional Availability Restrictions: Not available in Europe

Features / Benefits
  • Tip-filled arch structure provides maximum motion, pressure, and vacuum resistance in abrasive fluid applications
  • Composite fabric structure with welded, treated metal body ring maintains dimensional stability and pressure / vacuum resistance
  • Provides a wide range of antioxidant synthetic rubber
  • Retaining ring provides a metal surface that evenly distributes the bolt load, preventing damage to the flange during bolt tightening

Optional structure
  • Multi-arch for higher movements
  • Filled arch to eliminate dielectric buildup
  • Oversized arch for higher movements
  • Concentric or eccentric taper for pipes of unequal diameter
  • Custom drilling: ANSI, DIN, AWWA, BS, JIS and other special drilling types are available on request
  • End-to-end
  • Offset, lateral, angled and twisted

Retaining ring
  • Required for use in all applications, they provide a metal surface that evenly distributes the load on the bolts, preventing damage to the flange during bolt tightening
  • Standard material: mild steel with corrosion-resistant coating. Also available in galvanized or stainless steel

Control unit / rod
  • Recommended for most applications to prevent damage due to excessive pipe movement
  • Standard material: low carbon steel. Also available in galvanized or stainless steel
