Bobrick B-8231-34 Basin Mounting Kit

The B-8231-34 mounting kit is made for Bobrick lavatory mounted foam soap dispensers, models B-8231 and B-82316. It is the hardware that connects the soap pump assembly to the soap container below the deck. If you are servicing a different Bobrick dispenser series, this is not the kit for it.

Six pieces: gasket, funnel, shank and latch, O-ring, rosette washer, and mounting nut. That is the full set of hardware between the pump head on top of the basin and the container underneath, so a leaking or stripped deck mount can be rebuilt without replacing the whole dispenser.

Usually yes. Leaks at a lavatory mounted foam dispenser almost always come from the gasket or O-ring at the deck penetration, and both are in the B-8231-34 kit along with the shank and latch, rosette washer and mounting nut that hold the assembly tight to the basin. It covers the B-8231 and B-82316 dispensers.

No. This is mounting hardware only, the gasket, funnel, shank and latch, O-ring, rosette washer and nut. The pump assembly and the soap container are separate parts. Order this when the mounting components are worn or missing but the pump and reservoir are still good.

It mounts through the sink deck. The application is a lavatory basin: the shank drops through the mounting hole, the gasket and rosette washer seal and trim the top side, and the mounting nut draws it down from below. That is why it is called a basin mounting kit rather than a wall bracket.

It is a sensible shelf item if your buildings run B-8231 or B-82316 deck mounted foam dispensers. The gasket and O-ring are the wear items on a lavatory mount and they are what generate service calls; keeping the full six piece kit on hand means one trip instead of two. Standardize your dispensers on one of those two models and a single part number covers the fleet.
