Is the BANJO Bolt with Washers, Type D7 compatible with couplings R13, R14, D12, D17, D5, and D6 at 18 bar working pressure?

Yes. The BANJO Bolt with Washers, Type D7 is compatible with couplings R13, R14, D12, D17, D5, and D6 and is rated for a working pressure of up to 18 bar. Manufactured from nickel-plated brass, it offers durability, corrosion resistance and reliable, leak-free connections suitable for demanding industrial and technical applications.

Can the BANJO Bolt with Washers, Type D7 be used in corrosive or marine environments without additional protective coatings?

No. The BANJO Bolt with Washers, Type D7 is made of nickel-plated brass and offers good corrosion resistance for many demanding environments, but nickel plating and brass alone are not sufficient for prolonged exposure to highly corrosive or marine (saltwater) conditions. Marine environments accelerate galvanic and pitting corrosion; without additional specialized protective coatings or corrosion-resistant base materials (e.g., stainless steel grades rated for seawater or deeper protective treatments), premature corrosion, loss of mechanical integrity, and sealing failure can occur. Recommendation: for marine or highly corrosive applications use parts made of marine-grade stainless steel or specify additional protective coatings (e.g., thicker barrier platings, epoxy or polymer coatings, or sacrificial anodes) and confirm compatibility with saltwater and the system’s chemistry.
