Jabsco .65L Mini Accumulator Tank w/Internal Bladder

The Jabsco 0.65L Mini Accumulator Tank with Internal Bladder (part #30573-0003) is a compact pressure storage and pulsation dampening solution designed for marine water systems controlled by pressure switches or air-driven pumps. This accumulator tank stabilizes flow in yacht plumbing, RV freshwater systems, and pressurized saltwater wash-down applications by reducing pump cycling and minimizing pressure fluctuations between the supply and discharge points.

At 1.35 lbs and measuring 8 x 5 x 12 inches, the mini accumulator fits tight spaces aboard vessel engine rooms, galley cabins, and compact marine water installations. The internal bladder design separates pressurized water from the gas charge, extending tank service life and preventing corrosion from repeated cycling. The 0.65-liter capacity suits auxiliary water systems, head pressurization, and deck wash systems where full-size accumulators would consume valuable space. Jabsco's engineering ensures reliable operation across the freshwater, saltwater, and waste-management applications common to modern marine platforms.

This accumulator tank addresses a persistent problem in marine plumbing: rapid pump on-off cycling that generates noise, accelerates pump wear, and destabilizes water pressure during peak demand. Weekend anglers and cruising boaters benefit from quieter operation and consistent shower pressure; offshore fishing vessels and commercial marine operators rely on these tanks to protect delicate instrumentation and reduce electrical load on onboard systems. The bladder-type design is standard across the marine industry and offers superior reliability compared to diaphragm accumulators in saltwater environments where corrosion risk is elevated.
