  • 4-bolt type clamp with two gripping fingers and two clamp sections
  • Bolts in boss clamps are designed to bend as they are tightened, this allows the clamp to conform to the hose outside diameter
  • Always tighten bolts to their specified torque value
  • Periodic re-tightening of bolts is required due to "cold flow" phenomenon present in all rubber hoses
  • Recommended for steam service up to 450 deg F

Instructions:

  • 4-Bolt Dixon® Boss™ clamp bolt tightening sequence, using a torque wrench, begin tightening the bolts as follows: A) Back bolt (bolt with nut facing assembler that is furthest away from gripping finger) one full turn.
  • B) Front bolt (bolt with nut facing assembler that is closest to gripping finger) one full turn.
  • C) Snug by hand (if bolts are loose) nuts on opposite side of bolts just torqued.
  • D) Opposite side back bolt (bolt with nut facing assembler furthest away from gripping finger) one full turn.
  • E) Opposite side front bolt (bolt with nut facing assembler closest to gripping finger) one full turn.
  • F) Snug by hand (if bolts are loose) nuts on opposite side of bolts just torqued.
  • G) Repeat above procedure "a" through "f" until all of the bolts have reached the recommended torque.
  • H) Remove assembly from vise.

Safety Notes:

  • 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.
  • Replacement nuts and bolts are available, contact Dixon® for more information.
  • 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-lb.
  • Worn-out hose couplings can be dangerous.
  • They should be checked regularly and replace when necessary.
  • Each coupling user should review applications and add safety devices where indicated.
  • Note: Pressurized steam is an extremely dangerous commodity.
  • Only hose, fittings, clamps and accessory items that have been approved for steam service should ever be used!
  • Never use an unapproved item for steam service.
  • Always follow the manufacturer's product recommendations for pressurized steam handling.
