Transparent sight glasses

Sight glass with hexagon head and shoulder, made in one piece of transparent polyamide. It screws into the wall of tanks, gearboxes, multipliers and other machines, so that the oil level can be seen from outside.

Polyamide resists mineral oil, diesel, lubricants and most solvents, and keeps its shape up to 90 °C. Contact with alcohol-based fluids, hot antifreeze and water above 80 °C should be avoided. It seals with a fibre washer.

• Sizes: 1/4", 3/8", 1/2", 3/4", 1", 1.1/4", 1.1/2" and 2"

For walls thinner than 5 mm, the manufacturer recommends fitting with a nut. Check the thread of the hole before ordering.
