Couplings and clamps used with Gamrat hoses: hose clip with screw thread  clamping rings  flanged couplings  Camlock couplings  Perrot couplings  quick-connect couplings  threaded couplings.

Use:

• prevent the hoses from: 
  mechanical damage (excessive bending, twisting, wear-out, collapse, etc.) 
  thermal (high temperature, heated objects, flames, welding chips, etc.) 
  chemical
• check the condition of hoses and couplings on a regular basis 
• adhere to all standards and manuals related to a particular application
  Use couplings and clamps suitable for a particular application.
  Follow the manufacturer’s recommendations for couplings and clamps and the guidelines in the “Principles of Proper Assembly” and the “Principles of a safe use of the reinforced hoses.
