California residents see Prop 65 WARNINGS

• Six-bolt type clamp with three gripping fingers and three 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

Applications: For steam service up to 450 deg F

Instructions:

• 6-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) having "X" near it one full turn.
• B) Front bolt (bolt with nut facing assembler that is closest to gripping finger) of same segment one full turn.
• C) Moving to clamp segment to the left of the one just tightened, snug bolts by hand (if bolts are loose).
• D) Back bolt to one full turn.
• E) Front bolt one full turn.
• F) Moving to clamp segment to the left of the one just tightened, snug bolts by hand (if bolts are loose).
• G) Back bolt one full turn.
• H) Front bolt one full turn.
• I) Repeat above procedure "a" through "h" until all of the bolts have reached the recommended torque.
• J) 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.
