Decision Matrix I

Keep “VCR Type” Fittings in Critical Locations

Thread 9/16-18, Gland flange o.d. 0.50, Gasket o.d. 0.48

Upside

  • Status quo

Downside

  • Wind up torque
  • Component rotation
  • Galled sealing surfaces
  • Particles
  • Shock and vibrational loosening
  • Thermal cycle loosening
  • Only 1/8th turn tight
  • No gasket, destroys fitting
  • More maintenance time
  • More downtime
  • More leakage


Upgrade, Use OmniSafe “Anti Torque” Fittings

OmniSafe Compression Fitting

Upside

  • Easier assembly
  • Perfect alignment
  • No particles
  • No galling
  • No loosening
  • Compatible threads
  • Full 1/4 turn tightening
  • Safer

Downside

  • Smaller o.d. gasket/gland
  • Employee training
