Reflex glasses is made from high Borosilicate, It can be used with all media except steam at service conditions up to 6MPa and temperature up to 430 °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.

Now we have two kinds manufacturing technique:

1.One is as same with reflex Gauge Glasses, use moulds to make the semi-finished products, afterwards, ground and polish the two side to ensure optimal transparency. By this manufacturing technique, the definition isn’t good.

2.The other manufacturing technique is: At first, we manufacture 17mm thickness glass sheet, then cut the glass sheet according the detailed size and polish the side face for the smooth. This manufacturing technique glass is very clear, but the goods cost is higher.
