Information

Body: Steel, turned, plain finish, weldable

Shipping

Weld bushings 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 result that they can be used as sealing surfaces in connection with a sealing element or compound.
The significant 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.
