ELESA original design 
No thread is required for mounting the fluid sight glasses EN 545.2.
The obliquely arranged serrations and the elasticity of the plastic ensure that the fluid sight glass fits so firmly that even a limited over pressure can be contained.
The sight glass is molded in the body during the injection process and is therefore absolutely leak tight.
Assembly instruction:
Push in the fluid sight glass manually, then a soft-head hammer can be used to complete the insertion. The bore should be countersunk by 45°, the O-ring should be slightly greased.
