Universal Livewell/Bilge Pump Washer

SEAFLO Universal Livewell/Bilge Pump Washer

The SEAFLO Universal Livewell/Bilge Pump Washer (Model 04W003) is a high-performance sealing solution engineered for marine bilge and livewell pump systems. Manufactured from premium marine-grade polymer, this washer delivers a tight, water-resistant seal under the most demanding conditions — whether in freshwater lakes or harsh saltwater environments. Its universal fitment design makes it a direct replacement for SEAFLO pump models SFBP1-G800-04, G800-05, and G800-03, as well as any system utilizing standard 3/4" fittings, eliminating installation guesswork and reducing downtime.

Engineered for durability, the washer resists cracking, warping, and corrosion over extended periods of use. Its robust construction withstands UV radiation, extreme temperatures, and high humidity — conditions common in marine environments. Whether you are performing routine maintenance, completing a repair, or building out a new bilge system from scratch, this washer serves as a critical component that ensures a reliable, watertight connection between the pump housing and its fittings, minimizing water loss and maintaining consistent system pressure.

The washer is available in multiple pack quantities to suit both individual boat owners and commercial marine operators. Each unit is produced to tight tolerances and is trusted by boaters for OEM-quality replacement performance. Customers consistently praise the perfect fit and ease of installation, making it a go-to choice across a wide range of boat models and configurations.
