Hose coupling selection guide

CAUTION: Important Safety Information!

Choosing the correct coupling device is important for maximum hose efficiency and safety. Couplings must be applied properly. Incorrectly or improperly applied couplings can result in shorter hose life and hose failures. These failures can result in serious bodily harm or property damage. Hose couplings have been carefully engineered over the years to meet specific requirements with large safety margins. Some questions you should answer to help in choosing the proper coupling for a particular application include:

• What chemicals, materials, and environments will the device be exposed to?
  • Is it a dangerous, volatile, abrasive, or corrosive material?
  • Is the coupling material compatible with the media and environment?
  • Does the coupling meet regulatory standards prescribed for this media?
• What pressures and temperatures are involved?
  • Is it specifically a high, medium, or low pressure application?
  • Is it for a suction application?
  • Are the hose and coupling devices compatible, and how does the coupling device affect the assembly's pressure rating?
• What means of connection are required?
  • Threaded connections?
  • Locking devices or other special safety requirements?
  • Flanged?
