ATP Strong Plus polyurethane spiral hose. The Strong Plus spiral series was developed for use in and around painted or finished surfaces. The "PLUS" is an added 5 foot tail making this spiral the ultimate spiral for assembly line applications. This extra-long tail is made of shore a 60 durometer "SH" series soft-braided hose, which is ultra-lightweight and extremely flexible. Increased operator comfort is an advantage of including this soft braided tail. Manufactured with Shore A 98 durometer polyurethane strong tubing, Strong spirals will yield a working length of approximately 60 percent of the total length. ATP uses our durable, heavy-duty two-piece brass male rigid compression fittings. A union fitting with a non-marring polyurethane protective cover is used to join the Strong and "PLUS" sections of the spiral. Add an Oetiker swing coupler, a free angle swivel fitting or choose from our other accessories to create your ultimate spiral.
