3876-3 Boat Self-Bailing Cockpit Mounted Scupper Valve Kit

3876-3 Boat Self-Bailing Cockpit Mounted Scupper Valve Kit

Q: Are the screws stainless steel or zinc plated?

Yes the screws provided are stainless steel.

Q: does this product come with plastic ring, scupper, gasket and mounting screws?

The kit I bought had 3 different sized gaskets, but none fit the original ring so I returned it for a full refund - I assume it was intended for a different manufacturer.
