Orscheln’s Twist2Lock Fluid Indicator + Accuracy

Our Fluid Level Indicators are manufactured as a complete system, allowing for complete precision. A complete assembly includes a tube, locking cap, and indicator. The patented locking cap on the Twist2Lock Fluid Level Indicator increases the accuracy of fluid level, allowing for greater powertrain performance. Orscheln’s particular design eliminates oil leakage “blow-by” at the cap and at the engine block. Our locking cap eliminates loose or lost sticks caused by vibration.
