Bell & Gossett 189579 Replacement Bladder for B200 Expansion Tank
Keep your hydronic heating system operating at peak efficiency with the Bell & Gossett 189579 Replacement Bladder for the B200 expansion tank. As a genuine OEM replacement part, this bladder is engineered to the exact specifications of your original Bell & Gossett equipment, ensuring a precise fit and reliable long-term performance.
Product Overview
Expansion tank bladders are a critical component in closed-loop hydronic systems. They separate the system water from the pressurized air charge, accommodating the volume changes that occur as water heats and cools. Over time, bladders can fatigue, crack, or lose their elasticity — leading to waterlogged tanks, pressure fluctuations, and reduced system efficiency. Replacing the bladder with a genuine Bell & Gossett part restores proper tank function and protects the entire hydronic system.
