Expansion Tank 1-3/4

The JOES RACING PRODUCTS Expansion Tank 1-3/4 is an essential component for boaters and marine mechanics looking to maintain optimal cooling system pressure during extended periods of high-speed operation. Designed to capture overflow and eliminate air pockets within the coolant loop, this recovery tank ensures that your engine remains at a stable temperature even when pushing through heavy chop. By providing a dedicated space for fluid expansion, it prevents the messy and potentially dangerous venting of coolant into the bilge or engine compartment.

Constructed from high-grade aluminum with a clean natural finish, this expansion tank is built to withstand the corrosive marine environment while offering significant weight savings. The unit features a precise 1/8 inch NPT inlet and a 1/2 inch NPT outlet to facilitate efficient fluid transfer and air venting throughout the system. The integrated 1-3/4 inch tube mount allows for a secure, vibration-resistant attachment to structural tubing or rail systems, ensuring the tank stays firmly in place during aggressive maneuvers.

Whether you are rigging a high-performance offshore vessel or upgrading a standard inboard cooling system, the Expansion Tank 1-3/4 provides a professional-grade solution for fluid management. Its compact design allows for versatile placement in tight engine bays where space is at a premium and weight distribution is a critical factor. Experienced mariners will appreciate the reliability of this aluminum recovery tank when looking to buy a durable overflow solution that meets the rigorous demands of the water.
