Features and applications
GN 743.7 oil level sight glasses can be used on pressurised oil tanks. The seal between the brass body and the glass window is guaranteed by a packing ring in NBR synthetic rubber.
The coupling of the conical threading (d2) with a right female threading (d4) will improve with the more threads that are in contact.
Generally to improve the tightness of this type of level indicators a sealing element like teflon ribbon is used.
Special executions on request
Indicators with NPT conical threading.
