Forespar seacock constructed from Marelon. This material is of carbon fibre reinforced nylon construction, which is strong, durable and suitable for below waterline installations. This seacock has a full bore (the inside diameter of the ball is the same as the inside diameter of the hose connection) so there is no resistance.

This Marelon seacock comes complete with a through hull fitting with a mushroom style head. The other end of the seacock has a straight barbed hose fitting. It is fire resistant, UV resistant and is will not be affected by electrolytic corrosion. The seacock exceeds ABYC recommendations and meets all UL specifications.
