Product Description

GN743.8 Oil Level Sight Glass, Brass ESG Glass, Conical Thread

The conical thread of these oil level sight glasses, GN 743.8 makes a metallic seal possible. When tightening, the conical male thread R blocks itself with the appropriate cylindrical female thread Rp.

With the datum plane a the male thread R has the same thread diameter as the Rp female thread, so that it can be screwed in by hand. Stronger tightening using a tool increases the length of engagement and seals the screw connection.

Additionally a sealant (hemp or teflon band) is usually used. The R thread is roughened, so that the sealant does not shift when screwing in.

Oil level sight glasses GN743.8 can also be used on pressurised tanks. Pressure and vacuum pressure test data is available.
