Details

Acetylene Inline Test Gauge 0-250 kPa - 5/8" UNF LH

This commercial-grade inline test gauge is designed for rapid pressure diagnostics, regulator calibration, and leak detection in acetylene gas systems.

Key Specifications

  • Pressure Range: 0 - 250 kPa (Optimised for low-pressure tracking)
  • Inlet Connection: 5/8"-18 UNF Female LH (Left-Hand)
  • Outlet Connection: 5/8"-18 UNF Male LH (Left-Hand)

Product Benefits

  • Fail-Safe Safety: Left-hand threading prevents hazardous cross-connection with oxygen or inert gas lines.
  • Direct Inline Placement: Splices directly between your regulator and torch hose without requiring extra brass adaptors.
  • Fault Detection: The 250 kPa dial face provides crucial visual headroom to spot dangerous regulator "creep" before system pressure exceeds safe thresholds.
  • Acetylene-Safe Materials: Constructed strictly with alloys engineered to prevent dangerous copper-acetylide chemical reactions.

Primary Applications

  • Static Leak Testing: Isolate gas lines and monitor the dial face for pressure drops.
  • Dynamic Flow Tracking: Measure pressure stability while the torch flame is actively burning.

Regulator Verification: Test delivery pressure accuracy and valve seat integrity.
