Radium Engineering Fuel Pressure Gauge, 0-100psi - Universal

This high-accuracy fuel pressure gauge is suitable for all fueling applications. It features an acrylic lens with a silicone filled dial that reads from 0 to 100psi (0 to 6.9 BAR) with +/- 2% accuracy. The silicone fluid prevents the needle from vibrating for easy pressure readings. The internal bubble is normal. Rugged stainless 1-5/8" OD steel case (1-3/4" OD bezel) with nickel plated male 1/8" NPT fitting. Available with black bezel and housing only. NOTES The internal silicone fluid bubble is normal Over pressurizing can permanently misalign the needle calibration PTFE thread sealant paste should always be used on NPT threads Always use a PTFE based thread sealant paste or tape when installing the pressure gauge to ensure a seal on the 1/8" NPT threads. Tighten gently by hand, then use a wrench to tighten 1.5 to 3 turns past hand tight. IMPORTANT: Do not tighten the pressure guage past lightly hand tight by grabbing the gauge and hand threading. Tightening this way will damage the gauge. Once it is gently hand tightened, use a wrench to complete final turns.
