Compression vs Push-to-Connect DOT Fittings, which one is right for you?

Push to Connect DOT Fittings:
  • Pros:
    • Easy install, just slide your tubing into the fitting.
    • Less maintenance.
    • Lower chance of leakage.
  • Cons:
    • Cost more than the DOT compression fittings.

Compression DOT Fitting:
  • Pros:
    • Available in more sizes and configurations.
    • Can support a higher PSI rating.
  • Cons:
    • Require the use of tools to install.
      • The nut on a compression fitting must be tightened correctly in order to create a seal and guard against leakage. 
    • Maintenance: 
      • Compression fittings often need to be tightened to prevent or to halt leaks. 

When deciding which DOT fitting is right for your vehicle, you must take into consideration:
  • Pounds per square inch (PSI) pressure requirements
  • Thread type needed.
  • Type of tubing or hose you are using.
