SEAFLO Water Deck Filler Cap
The SEAFLO Water Deck Filler Cap (SFCW1-01) is a versatile, keyless deck filler solution engineered for freshwater tanks across a wide range of marine, RV, and vehicle applications. Built from UV-stabilized black nylon with a white body, this cap resists fading and cracking from prolonged UV exposure, ensuring long-term durability in outdoor environments. The blue easy-open screw top allows tool-free access — simply twist by hand to open or close, making it ideal for fast-paced marine and outdoor use.
A built-in high-grade O-ring seal ensures a tight, watertight connection that protects tank contents from dirt, debris, and moisture contamination. The included stainless steel retaining chain prevents the cap from being lost or misplaced during filling operations. Six pairs of metallic silver stick-on name plates are included, allowing users to clearly label the application: Fuel, Petrol, Gas, Water, or Diesel.
