## Description

Dixon® 4-bolt clamp, series: Boss™, 1-34/64 to 1-46/64 in nominal, 3-1/2 in length, 3-3/32 in width, 18 ft-lb, brass band, domestic.

Features

- 4-bolt type clamp with 2 gripping fingers and 2 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

- Boss™ clamps are for single use only, once removed they are to be discarded

- Recommended for steam service up to 450°F

- 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

- Torque values for clamps are based on dry bolts, the use of lubricant on bolts will adversely effect clamp performance

- 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

- Warning: this product contains a chemical known to the State of California to cause birth defects or other reproductive harm

- Do not use in connection with drinking water

- Wash hands after handling
