The selection charts are used to select the proper type of STRAUB-FLEX or STRAUB-OPEN-FLEX coupling for the application pressure. Separate charts are used for the TYPE 2 and 3 designs.
For complete dimensional data, see Page 10 or please consult the factory, STRAUB Technical Manual, or an authorized STRAUB Distributor.
Other sizes available upon request.
*STRAUB-FLEX is also available in a two-piece construction - useful for very tight spaces and for ease of handling.
STRAUB-OPEN-FLEX 2 couplings are available in two different styles depending on model and size:
• Slotted Casing
• 2-Piece Execution
STRAUB-OPEN-FLEX gaskets are cut and riveted to casing. Please consult your STRAUB professional for more information
All STRAUB couplings require correct use of a torque wrench for safe and proper installation. STRAUB couplings must be torqued to the specified value printed on each individual coupling. Failure to do so can result in injury or death.
