8687

Application
The 8687 Junior Top Mount Model Threaded Head Medium Duty Spiral Gauge is designed for use in measuring liquid levels in gasoline, diesel fuel, bio-diesel, hydraulic and lubricating oils where space restrictions prevent the use of a swing-arm style mechanical gauge. It is ideal for medium duty construction & agricul- ture, lawn & garden, marine and recreational vehicle applications.

General Information & Features
• Field Replaceable Snap-On Fractional Dial
• Solid One-Piece Head Construction, No-Leakage Path to Dial

The Threaded Head mounting of the 8687 Spiral Gauge allows a tight seal that restricts vapor loss. The “Screw In” mounting contributes to the gauges adaptability for use in restricted areas.

The 8687 Threaded Head Spiral Gauge is designed for top mounting with an easy to read fractional dial. It is available in lengths from 6 to 20 inches.
