Is the BAUER hose end lever connector plug, carbon steel, B.8 rated for continuous use at 20 bar and within -20°C to +50°C?

Yes. The BAUER hose end lever connector plug, carbon steel, B.8 is rated for continuous use at up to 20 bar (for sizes up to 89 mm) and for operation within the temperature range −20°C to +50°C.

Can the BAUER hose end lever connector plug, carbon steel, B.8 be safely used in seawater or highly corrosive environments?

No — the BAUER hose end lever connector plug, carbon steel, B.8 is not recommended for seawater or highly corrosive environments. Although galvanized carbon steel gives good general corrosion and wear resistance for many industrial and construction applications, galvanizing is insufficient for prolonged exposure to chloride-rich seawater or aggressive chemical atmospheres. In such conditions the coating will deteriorate, leading to accelerated corrosion of the base carbon steel, reduced mechanical integrity and potential sealing/failure issues. If you need a connector for seawater or highly corrosive environments, choose materials specifically suited to those conditions (for example stainless steels with appropriate grade and testing for chloride resistance, duplex stainless, bronze/brass alloys rated for seawater, or non‑metallic/polymer alternatives) and verify compatibility with the fluid, pressure (up to 20 bar for smaller sizes, 12 bar for larger), temperature range (−20°C to +50°C) and installation conditions. Regular inspection and maintenance or additional protective measures (e.g., sacrificial anodes, specialized coatings) may also be required.
