Ermeto SKA-RB tube bend weld nipple types can be assembled in any Ermeto tube fitting. Ermeto tube bend weld nipples are available in all sizes from 6 – 38 in the light and heavy series. The Ermeto tube bend weld nipple is welded to the tube end without the O-ring. Assembling beforehand a retaining nut with the right size and orientation should not be forgotten. Special guidelines and regulations may apply to the pre-handling of the tube end, the welding procedure, welding personnel qualifications, post-processing and testing and documentation of the weld connection.
