Ermeto SKA and SKA-ORB weld nipple types can be assembled in any EO tube fitting. Ermeto weld nipples are available in all sizes from 6 – 38/42 in the light and heavy series.  
The Ermeto 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.

Markets:
• Press construction
• Heavy machinery building
• Power station construction
• Shipbuilding

Applications:                                                                                                                                            
• Suitable for general hydraulic applications.

Features/ benefits:
• Ermeto weld nipples can be combined with all EO fittings, so that the fittings can be used in a broad range of applications.
• The elastomeric seal acts as a primary sealing element, making the connection leak-proof. So maintenance and re-work costs are substantially reduced.
• Even after continuous operation for years under extreme conditions, the soft-seal weld nipple does not have to be retightened. This means that the connector has a long life and maintenance and servicing costs are noticeably diminished.
• Insufficiently assembled Ermeto weld nipples do not come apart without warning. The user can react early enough because the connectors indicate the problem by leaking and they can be retightened.
• Ermeto weld nipples can be undone and then re-assembled any number of times. The longevity of the connector is thereby increased and costs saved.
