Shatter-Resistant Oil-Level and Temperature Indicators
Nylon Plastic
Nylon Plastic With Aluminum Guard
Nylon Plastic With Glass-Filled Nylon Guard
Nylon Plastic With Steel Guard
The nylon body and window make these indicators shatter resistant. Use them to simultaneously monitor hydraulic fluid or oil level and temperature. All are UV resistant for use outdoors.
Indicators with a glass-filled nylon or aluminum guard, or no guard, mount from the inside of your tank through unthreaded holes. Glass-filled nylon guards are more impact resistant than aluminum guards.
Indicators with a steel guard have a lower profile and can withstand higher pressure than other indicators. Mount them from the outside of your tank through threaded holes.

Through-Wall Sights
For Clear Liquid
For Dark Liquid
Mount these sights from the inside of your tank and secure with a lock nut. They install through unthreaded holes in tank walls.
Sights for dark liquid have a reflector that makes liquid easy to see, especially in low-light conditions.
303 stainless steel sights are more corrosion resistant than aluminum sights.
