A tank coupler for releasably interconnecting serially connected tanks. The tank coupler includes threaded engagement portions which are threadedly engageable with ports formed in the tanks. The coupler defines a central fluid passage which receives in a sealing relationship, a riser tube associated with a first tank and a riser tube associated with a second tank. A snap fit mechanism maintains the engagement of one riser tube with the fluid passage in order to control separation of the riser tube from the coupler when the tanks are separated. O-ring seals mounted in grooves forming part of the fluid passage sealingly engage the periphery of the riser tubes and inhibit fluid leakage between the riser tubes and the coupler. The tank coupler also defines a second fluid passage which cross-communicates the interiors of the tanks. Distributors mounted on opposite ends of the second fluid passage inhibit material from moving from one tank to the other while permitting fluid flow.
