Is the Walterscheid™ ROV Carbon Steel Plug compatible with both L (light) and S (heavy) series hydraulic fittings?

Yes. The Walterscheid™ ROV Carbon Steel Plug is available in both the L (light) and S (heavy) series versions, making it compatible with hydraulic fittings from either series. Manufactured from carbon steel with a Guardian Seal™ galvanic coating, it provides durable, corrosion-resistant sealing for a wide range of system requirements.

Does the Walterscheid™ ROV Carbon Steel Plug’s Guardian Seal™ galvanic coating provide protection suitable for offshore or saline environments?

The Walterscheid™ ROV Carbon Steel Plug’s Guardian Seal™ galvanic coating offers enhanced corrosion protection compared with untreated carbon steel and is designed to extend service life in harsh operating environments. However, galvanic coatings vary in composition and thickness, and while Guardian Seal™ provides "outstanding protection" for many demanding hydraulic applications, galvanic coatings alone are generally not considered a full substitute for specialized corrosion-resistant materials (e.g., stainless steels, duplex alloys) or thicker protective systems in prolonged offshore or highly saline environments. For short to moderate exposure, splash zones, or protected installations, the Guardian Seal™ will significantly reduce corrosion risk. For continuous immersion in seawater, highly aggressive marine atmospheres, or critical offshore applications where failure risk must be minimized, specify materials and coatings qualified for marine service or consult Eaton/Walterscheid for corrosion test data, certifications, and recommended configurations (e.g., alternative materials, additional coatings, or sacrificial protection).
