Brand New, created specifically for our models 425, 350, 500 and 400 Dryerboxes but with very innovative custom ends. This is only available from our store and features an adaptive coupling on one end and a special expanded end on the other that better secures these sensitive connections. It measures 4" in diameter by 39" long (when stretched out) and 13" when compressed. This product has been custom cut to best fit the models 425, 350, 500 and 400 Dryerbox conditions. Any longer than 13" compressed may prevent the dryer from being located right against the wall. This aluminum flex product is almost always specified by the appliance manufacturer and offers the most efficient flexible transition hose. It is the most energy efficient to use.

to purchase along with our 425, 350, 500 and 400 models. Use PF-448 for 4D and 3D.
