Radium - Mechanical Fuel Pressure Gauge (0-100 PSI / 1/8" NPT)

The Radium Engineering 0-100 PSI Mechanical Fuel Pressure Gauge provides rock-solid, vibration-free fuel pressure monitoring for fuel rails, regulators, and distribution blocks. Designed with an internal silicone fluid dampened dial, the gauge needle remains completely steady under severe engine vibration, providing accurate readings within +/- 2%.

Key Performance Features:

• Silicone Dampened Movement: High-viscosity silicone fluid dampens pump pulsation and chassis vibrations, ensuring legible needle readings.
• 0 to 100 PSI Range: Dual scale display reading 0 to 100 PSI (0 to 6.9 BAR) with high-visibility white markings on a stealth black dial face.
• Rugged Stainless Steel Case: Compact 1-5/8" OD stainless steel housing with a black anodized bezel designed for tight engine bay packaging.
• Standard 1/8" NPT Male Fitting: Screws directly into fuel rails, fuel pressure regulators, or gauge adapter blocks with standard 1/8" NPT ports.
• High Heat & Chemical Resistance: Engineered to withstand aggressive underhood temperatures and fuel vapors.

Notice: Standard male 1/8" NPT threads require PTFE thread sealant paste upon installation. Over-pressurizing beyond 100 PSI can permanently misalign needle calibration.
