About Marine & Boat Rubber Washers
Larger, heavier rubber washers for boats, docks and waterfront hardware — deck fittings, thru-hull fastener sealing, rail mounts, transducer brackets and pontoon hardware, in ODs from 1" to 4". Salt, sun and constant moisture destroy the wrong rubber fast: choose EPDM for the best UV, ozone and saltwater resistance, or Neoprene where fuel and oil splash are also in play.
Read the complete marine and saltwater guide for material picks by application, compare all seven chemistries in the material comparison, or find any dimension with the Size Finder.
FAQ
What rubber washer is best for saltwater?
EPDM — it shrugs off UV, ozone and salt spray for years where Nitrile and Natural Rubber crack and harden. Use Neoprene when the hardware also sees fuel or oil.
