Product Details

  • Each wedge is manufactured with an elongated contour that evenly matches the outside circumference of each nominal diameter of ductile iron pipe
  • This elongated contour also eliminates the concern of damage to both the pipe wall and the interior cement mortar lining caused by point loading, even on the thinner pressure classes of ductile iron pipe
  • ONE-LOK™ SLDEH’s precision contoured wedges provide proper contact and support of the ductile iron pipe wall
  • The SIGMA ONE-LOK™ series SLDEH is a mechanical joint restraining gland that implements a series of individually activated wedges into the mechanical joint follower gland
  • The SIGMA ONE-LOK™ series SLDEH ductile iron pipe joint harness consists of series SLDE mechanical joint, wedge-action restraining gland installed on the plain end of the pipe joint and incorporates high strength, low alloy, corrosion resistant
  • The SIGMA two piece back-up ring series SG has oblong ears to accommodate varying outside diameter of DI pipe bell
  • The breakaway top ensures proper engagement of the wedge segment at the time of installation
  • ONE-LOK™ SLDEH’s wedge actuating bolt provides the installer with a visual torque indicator
  • This action causes the primary contact edges to grip the pipe and effectively restrain all classifications of ductile iron pipe
  • When the wedge segment is engaged by the actuating bolt, the primary contact edges of each wedge segment lock onto the pipe wall
  • Requires Certification
