Description
Radium Fuel Pressure Gauge 0-100psi
Application: Universal
Part Type: Fuel pressure gauge, 0–100psi (gauge only)
Part Number: 20-0029
This high-accuracy Radium fuel pressure gauge is suitable for all fuelling applications. It reads 0–100psi (0–6.9 bar) with ±2% accuracy through an acrylic lens, and the silicone-filled dial steadies the needle so readings are easier to take.
The rugged stainless steel case has a nickel-plated male 1/8" NPT fitting with a black bezel and housing. The 20-0029 is the gauge only – Radium also offers it bundled with 8AN ORB, 6AN inline and 90° adapters.
Key Features
- 0–100psi Range: 0–6.9 bar with ±2% accuracy

- Acrylic Lens: Clear, easy-to-read face
- Stainless Steel Case: Rugged construction with black bezel and housing

What's Included
- 1x Radium 0–100psi fuel pressure gauge
Important Notes
- An internal bubble in the silicone fluid is normal
- Over-pressurising can permanently misalign the needle calibration – do not exceed the gauge range
- Always use PTFE-based thread sealant paste on NPT threads
- Install by gently hand-tightening, then turn 1.5–3 turns past hand-tight with a spanner
- Do not thread the gauge in by gripping and turning the gauge body past light hand-tightness – this will damage the gauge
- Requires a 1/8" NPT female port or suitable adapter
