Product Details

  • 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 restrainer rod connected to a standard mechanical joint follower split gland behind the shoulder of the bell end of the pipe joint, the SIGMA two piece back-up ring series SG has oblong ears to accommodate varying outside diameter of DI pipe bell
  • Mechanical joint restraining gland that implements a series of individually activated wedges into the mechanical joint follower gland
  • Precision contoured wedges provide proper contact and support of the ductile iron pipe wall
  • Wedge actuating bolt provides the installer with a visual torque indicator, the breakaway top ensures proper engagement of the wedge segment at the time of installation, unlike other actuating bolts, the ONE-LOK SLDE is manufactured with a proprietary quality control system that ensures the breakaway tops will activate at the correct torque
  • The breakaway top is sized to match the same dimensions of the bolts and nuts used to assemble the mechanical joint fitting and follower gland, eliminating the need for special installation tools, once engaged, the actuating bolt leaves a residual hex-head shank, allowing post-installation disassembly of the restrained joint, if necessary
