Threaded plugs, Steel

Promotional pricing
Volume Discount

The dimensions of the threaded plugs GN 749 comply with DIN 908, but deviating from the latter is the elastic sealing ring (rubber). This sealling ring is retained in a radial undercut in the mating face which prevents it from dropping out and in particular it does not extrude when the plug is tightened.
The details relating to the permissible opreating pressure are non-binding recommended values and rule out any liability. They constitute no general warranty of quality and condition. The user must determine from case to case whether a product is suitable for the intended use.
