Unisource Manufacturing, Inc. manufactures the world’s finest high-pressure thermoplastic hose.
Series 4700LT Low-Temp hose outperforms all other hose products intended for the transfer of liquid carbon dioxide.
Series 4700LT is constructed using a special low-temperature polyester core compound, polyester reinforcing, and a special perforated polyester cover. All layers are bonded. Unlike standard thermoplastic SAE 100R7 spec hoses that become stiff and unwieldy when transferring low-temperature liquids, Series 4700LT remains flexible in liquid transfer as low as -65°F. The perforated cover avoids bubbling, a common problem with many thermoplastic hoses. Style 4700LT-FDA is available on special order with gray cover and FDA tube. Series 4700LT is available on full 250 foot reels and along with the Unisource HH10 swaging system and RT Style couplings, is ideal for field fabrication. Coupled lengths are also available, including fill hose assemblies with vent hose attached. Use Series 4700LT for supply hose on reels installed on delivery vehicles and for connection from fill box to liquid cylinders.
