Features
  • Replacement nuts and bolts are available, contact the factory for more information.
  • The bolts used in the Boss interlocking clamps are not standard bolts. They vary from standard bolts in their length, diameter, overall thread length and material hardness. These bolts can be retorqued, but it is not recommended that, the bolts or clamps be reused, as they are designed for a single bend only. Dixon recommends using only factory supplied replacement bolts.
  • Torque values for clamps are based on dry bolts. The use of lubricant on bolts will adversely effect clamp performance. Do not lubricate nuts and bolts.
    Recommended torque rating in ft. lbs.
Safety Alert: Boss couplings and the steam quick disconnects are the only Dixon couplers recommended for steam service
