An insulated jacket is the perfect accessory to help maintain a tepid temperature within the Hughes model 10GFEW OptiWash™ 10-gallon eye wash station. The jacket is best suited for locations where extreme heat or sun exposure could cause water to overheat, but also helps delay freezing in cold temperatures. Simple design makes it easy to put on or take off an existing Hughes model 10GFEW 10-gallon eye wash station. Eyewash sold separately.
