SEAFLO 2 Gallon Pre-Pressurized Accumulator Expansion Tank, 87 PSI
The SEAFLO 2 Gallon Pre-Pressurized Accumulator Expansion Tank (Model SFAT-087-021-01) is designed to reduce pump cycling and dampen pressure fluctuations in marine, RV, off-grid, and cabin water systems for smoother, more consistent water flow. Pre-pressurized for quick setup and adjustable via the integrated Schrader air valve, it supports pressures up to 87 PSI and connects with 3/4″ MNPT inlet/outlet fittings for easy integration into existing plumbing. Manufactured with corrosion-resistant polypropylene and stainless steel components, the compact 7.87″ × 7.87″ × 13.0″ tank helps absorb water hammer, reduce noise and vibration, conserve pump energy, and extend pump life. Its universal 3/4″ MNPT connection and space-saving design make it suitable for tight installations aboard boats, RVs, caravans, or remote water systems.
