Is the Carbon Steel Nipple, Type LN, To Be Added compatible with UM type nuts (EC‑105…) for a leak‑proof hydraulic or pneumatic connection?

Yes — Carbon Steel Nipple, Type LN, To Be Added is compatible with UM type nuts (EC‑105…) for a leak‑proof hydraulic or pneumatic connection. The LN nipple features a spherical profile and a 60° sealing cone aligned with DIN 7608, and when used with the recommended UM type nut (EC‑105…) provides precise geometry, robust construction, and a reliable seal suitable for hydraulic and pneumatic systems.

Can the Carbon Steel Nipple, Type LN, To Be Added withstand exposure to corrosive environments without additional protective treatments?

Carbon Steel Nipple, Type LN, To Be Added Format: The nipple is manufactured from carbon steel with a protective galvanized coating, which provides good general corrosion resistance and wear protection for many typical hydraulic and pneumatic applications. However, in highly corrosive environments (salt spray, acidic or alkaline media, chemical exposure, prolonged outdoor marine conditions) galvanized coating alone may not provide sufficient long-term protection. For such conditions additional protective treatments (e.g., thicker or specialized plating, corrosion‑resistant alloys, epoxy or polymer coatings, or cathodic protection) or selecting a stainless or specially treated material are recommended to ensure longevity and prevent premature failure. In summary: acceptable for standard industrial environments without extra treatment; for aggressive/corrosive environments, additional protection or alternative materials are advised.
