ARGCO's MODEL 109  is a truly rigid grooved pipe coupling which does not allow for any axial movement, angular movement and/or rotational movement under normal service conditions.  

Captured-Bolt Design: Features flanged nuts and painted bolt ends to help prevent the nuts from threading off the bolts.
1-1/4" Coupling includes 3/8" bolt and Flange Nut (for use with 9/16" socket)

 UL Listed & FM Approved   

Benefits:    
•Fast, efficient installation – no disassembly required    
•True rigid performance – zero movement once installed    
•No dropped parts on the jobsite    
•Aligns with ANSI and NFPA standards    
•Ideal for fire protection systems and rigid piping applications    

Applications:    
•All piping including mechanical rooms where no angular or axial movement is desired    
•Dry-system fire protection pipelines     
•Hot water systems (up to 230 degrees F) 

All ARGCO EPDM gaskets are pre-lubricated, allowing the gaskets to be installed on the pipe without applying lubricant.
