Safety - By reducing chances for error, chances for leaks are reduced.
- There are 13 incorrect configurations of a two-ferrule instrument tube fitting like (Swagelok).
- There are only 2 incorrect configurations of a Parker CPI single-ferrule tube fitting.
- Parker CPI single-ferrule fittings move a key sealing point in front of the tube grip point. This greatly reduces potential problems from vibration and thermo-cycling versus the two-ferrule instrument tube fitting design.
Simplicity - By design, Parker CPI single ferrule tube fittings are easier to work with than dual-ferrule instrumentation tube fittings like (Swagelok).
- Less torque is required to install single-ferrule Parker CPI fittings than two-ferrule instrument tube fittings.
- With single-ferrule Parker CPI there are fewer components to stock, re-order, and carry around the plant.
Service Life - The Parker CPI moly-impregnated stainless steel nut provides more remakes and less thread galling versus silver coated threads used in two-ferrule designs like (Swagelok).
Interchangeability - Parker CPI single-ferrules are fully interchangeable with Swagelok dual-ferrule systems and can be used in either Parker or Swagelok fitting bodies.
