For many years, bronze has been the material of choice for use in underwater marine applications such as thru-hull fittings and seacocks. It outperformed many other metals and alloys and has stood the test of time. Until now. Designed and made in New Zealand, TruDesigns marine fittings are precision moulded from a glass reinforced Nylon composite material which provides both maximum strength and durability.

TruDesign ball valves (seacocks) control thru-hull inlet and outlet flow requirements, above and below the water line. The ball and seal ring are moulded in a PTFE filled polymer for lubricated, smooth continuous ease of operation. This material resists marine growth, such as barnacles, preventing them from seizing up the valve.
