Whitecap Pipe Deck Fill 1-1/2" Waste

The Whitecap Pipe Deck Fill 1-1/2" Waste is a marine-grade deck fitting designed for sailboats, cruising vessels, and commercial watercraft requiring reliable wastewater system management. This 316 stainless steel deck fill serves as the primary access point for holding tank maintenance and waste system inspection on deck. Built to withstand the demanding salt-water marine environment, this waste deck fill combines durability with practical functionality for boat owners and marine technicians who demand dependable, corrosion-resistant hardware.

Manufactured from premium 316 stainless steel, the Whitecap Pipe Deck Fill features a 3-3/8" flange that provides a wide, stable mounting surface and secures flush to your deck. The 1-1/2" pipe opening accommodates standard waste system hoses and pump-out equipment, while the included chain tether prevents cap loss overboard—a critical safety feature on any vessel. Installation is straightforward using three #10 fasteners supplied with the unit, and the compact 4 x 2 x 4 inch footprint minimizes deck space requirements. A replacement cap and chain assembly (P/N 6074) is readily available for future wear or damage, ensuring long-term serviceability and reduced downtime.

This deck fill is ideal for cruising sailors, fishing vessel operators, and marine facility managers seeking reliable holding tank access in exposed weather conditions. The 316 stainless steel construction significantly outperforms standard 304 alloys in salt-water environments, resisting pitting and corrosion that can compromise deck integrity. Compatibility with 1-1/2" waste systems is standard on most cruising sailboats and mid-size powerboats; verify your existing hose diameter before purchase to ensure proper fit and system function.
