Forged or Hot Stamped Manufacture

SeaSeal products are manufactured and tested in our ISO 9001 accredited factory in England where, for nearly a century, a skilled work force have been producing high quality, forged, non-ferrous metal products. These products are often for safety critical and high specification applications. These include not only marine applications, but also high pressure valve bodies for the oil and gas supply industries, fire suppression systems, specialist components for the motor industry and detailed, high quality architectural fittings. Marine products include windlass components, commercial life raft valves and bespoke plumbing fittings for boat builders.

SeaSeal seacocks and fittings are made from forged, traceable dezincification resistant alloy (DZR). Forging is a process where a metal billet is heated and then stamped. In the case of a seacock, with up to 1,000 tons. This strengthens the metal at the molecular level and results in a consistent, strong component. Most available marine products are cast. This is a process where the metal is completely melted and then poured into a mould to form the shape. This produces a weaker product, which can be more porous and brittle and may contain voids; which weaken it further.

Once forged, the components of a SeaSeal seacock are precision machined to achieve a high level of finish and durability, with a smooth reliable action that will give many years of safe service, even in the most inhospitable environment.

Our increasing range of associated through hull and internal fittings are manufactured to the same standards to give a consistent level of quality and reliability throughout the safety critical water systems on board.

Fully Serviceable Winterisation

1 1/2” SeaSeal Seacock with the side of the body cut away. This shows the cone within and exposes the PTFE seal surrounding it. Also note the thickness and quality of the valve body and the retaining nut and locking yolk above.

A 3/4” SeaSeal seacock, before the bore is drilled, cut in half. This shows the fit of the cone into the body, with a sump beneath and the section of the seal channel at the top where a PTFE seal allows for adjustment whilst maintaining the seal to preclude any leakage up to the thread of the retaining cap.
