GN 7490 Welding Socket with & without Collar

Welding sockets GN 7490 are used in container construction or in hydraulics for mounting instruments such as oil level sight glasses or locking caps. The plane surfaces are machined, with the effect that they can be used as sealing surface in connection with a sealing element or compound. The favourably dimensioned wall thickness prevents deformation or burn-through during welding. Type B is used if exact positioning through the mounting bore or a low construction height is required.
