Applications
As a replacement for conventional glass discs in the following assemblies:
- Circular sight ports to DIN 28120 or similar
- Circular sight ports to DIN 28121
- Screwed sight glasses similar to DIN 11851
- Sight flow indicators
Advantages
- Reliability against total failure – the possibility of sudden unexpected rupture is totally excluded
- High resistance to bending and over-tightening offers simple and fast installation with no risk of breakage
- Extreme resistance to impact, pressure and temperature
- Reusable in the same or other applications – conventional glass is not
- Wide acceptance in the European & American chemical industries
