DNV GL type-approved marine bronze sea cocks (through-hull seacock valves) and sea valves for vessel hull penetrations below and above the waterline. Manufactured from dezincification-resistant naval bronze (CuSn5Pb5Zn5 gunmetal, CC491K / ASTM B62) and nickel aluminium bronze (NAB, CuAl10Ni5Fe4, CC333G) for superior seawater corrosion resistance. Sizes DN15 (½") to DN300 (12"), PN10 to PN25. Tapered plug type (BS 5154) and ball-type (BS 5351) sea cocks stocked. Lever-operated with positive-shut isolation. Used on merchant vessels, naval vessels, offshore supply vessels (OSVs), and barge hulls transiting the Red Sea and Arabian Gulf. DNV GL and Lloyd's Register type-approval certificates available. Flanged (PN10/ASME 150) and plain-end connections.

Type 02

Deck Penetration Fittings & Hull Fittings

Marine-grade deck penetration fittings, hull penetration frames, and watertight bulkhead penetrations for vessel and offshore platform construction. Products include: watertight cable transit frames (multi-cable and single-cable) to IEC 60092-352 and SOLAS requirements; deck pipes (galvanised steel, stainless SS 316L, naval bronze) for securing to deck plating with raised collar; strum boxes (strainer boxes, Kingston valves) with bronze body and strainer screen for sea suction inlets; and storm valves (flap type, spring-loaded) for overboard discharge lines. Sizes DN15–DN400. Class-society approved: DNV GL, LR, ABS. Used on jack-up rig bilge suction, ballast piping penetrations, and deck washdown systems at Saudi Arabia offshore installations.

Type 03
