Product Description

Product description

Reflex glasses is made from Borosilicate, It can be used with all media except steam at service conditions up to 4MPa and temperature up to 260 °C.

The side facing the medium chamber is provided with moulded grooves set at 90° angles. The moulding process increases the resistance of the glass grooves to wear; the skin which the glass attains during moulding gives it maximum smoothness and hardness.This makes it extremely resistant to the attack of boiler water.

It is used in level gauge in boiler for water position. It is also named: Reflex Gauge Glass, Sight glass, Reflex Glasses, Reflex sight glass, Spares For level Gauge.
