The large capacity, 55 gallon Upright Polymer Reservoir from Buyers Products is lightweight, rustproof, and virtually maintenance free. It's ideal for applications where weight is a factor. The reservoir is best for short run time hydraulic operations such as dump and roll-off applications. It features dual 2 in. NPT field serviceable ports, a 2 in. by 1-1/4 in. screw-in diffuser, and a chain-mounted 40 micron filler breather cap. Constructed of reinforced high-density polypropylene, the reservoir features a heavy duty strapless hold-down system.
