VCR Fitting Installation Instructions

Step-by-step guidance for a reliable, leak-tight metal gasket face seal

Before Installation
  • Ensure all components are clean and free from dust, oil, or particles
  • Verify correct gasket material for gas compatibility
  • Inspect sealing faces for scratches or damage
  • Confirm correct size and thread type
  • Use proper torque wrench (recommended)
Installation Steps
  1. Insert the Gasket — Place a new metal gasket into the female face seal fitting. Ensure it sits flat and centered.
  2. Align the Fittings — Carefully align the male and female sealing faces. Avoid misalignment to prevent surface damage.
  3. Hand Tighten — Thread the gland nut by hand until snug. Ensure smooth engagement — do not cross-thread.
  4. Final Torque Tightening — Using a calibrated torque wrench, tighten to the manufacturer's recommended torque value.
