Fluid Sight Glasses GN 743.8

Product description

Information

The conical thread of GN 743.8 fluid sight glasses makes a metallic seal possible. When tightened, the conical external thread R wedges itself within the corresponding internal thread Rp.

At the reference level “a”, the external thread has the same thread diameter as the internal thread, so that it can be fastened in by hand up to “a”. The tightening with a tool increases the screw-in length and seals the screw connection. In addition, a sealant (fibrous or teflon tape) is usually used. The ”R” thread is “roughened”, so that the sealant does not shift when screwing in.

These fluid sight glasses can also be used on pressurized tanks. Tests regarding maximum pressure are available.
