Band Clamp

Safety Recommendations The use of band style clamps has proven to be an effective means of retaining hose couplings in industrial hose. To achieve proper retention and sealing of the hose coupling in the hose, it is imperative that these clamps be installed correctly. Please follow the manufacturer’s recommendations as to the proper selection and installation of band clamps. When installing multiple clamps, the buckles must be offset around the hose, (reference page 8), eliminating the possibility of a straight line leak under the buckle area. Improper installation of band clamps Proper...

Band and Buckle Material availability: • Stainless steel • Galvanized steel Installation tools: • Roll over tools C2, 51960 (other manufacturer’s tools may be used) The band and buckle system is an economical method of securing fittings to large diameter rubber hose (2" and above). Note: Do not use strapping and buckles made of different metals. Example: Stainless steel strapping must be used with stainless steel buckles.

Clamp Selection Pre-Formed Band Clamps 1. Measure the hose Outside Diameter (O.D.) with a diameter tape. 2. Select the clamp having an Inside Diameter (I.D.) as close to the measured hose O.D. but not less than 1/4". This is so that the clamps can be slid onto the hose before the couplings are inserted. Example: Hose O.D. is 2-11/16" Hose O.D. is 2-7/8" Use 3" I.D. clamp Use 3-1/2" I.D. clamp Band and Buckle Caution! Strapping edges can be extremely sharp! All necessary precautions should be taken to prevent installer’s hands from being cut during the assembly process. 1. Measure the hose...

Preparing the hose for assembly Cut Hose to Length. Cut Ends Square. (Lack of a square cut on the hose end can reduce coupling retention.) For hoses having a helical wire: 1. Determine the direction the helical wire is pointing in. This is necessary as proper installation of pre-formed band clamps and bands and buckles rely upon proper orientation of the clamp tail with the helical wire. See illustration below. 2. If helical wire is not used for static grounding, trim the wire back into the carcass of the hose. This is to prevent injury during use of the assembly. Clean Hose I.D. Mark the...

Operating Instruction for the F1 Installation Tool 1 Push tension handle all the way forward. Insert the clamp tail and push all the way into tool. 2 Tighten the clamp with short downward strokes. Tension handle should be in down position at completion of tightening clamp. If clamp tension needs to be released before locking, move slide back against spring. This raises the pulling dog. 3 Holding tension handle down, lock clamp by hitting punch at least twice with mallet. 4 Hold hose and raise the tool back and forth to break off clamp tail. Remove from tool by operating tension handle. when...
