General information
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.
