Hoses for Extremely Cold Environments

Two new hose models from Parker Hannifin are engineered to work in temperatures as low as -70°F (-57°C)—the industry’s lowest temperature rating—while maintaining high performance.
Specifically designed, tested and field-proven for high-impulse, heavy-duty applications, Parker’s 472LT and 722LT hoses are claimed to be ideal for mining, drilling and construction equipment used commonly throughout northern Canada and the Arctic Circle. The No-Skive, two-wire braided 472LT hose is rated for high-pressure applications that operate at up to 5,800 psi (40 MPa), and uses Parker’s standard 43 Series fittings. Parker’s 43 Series fittings are offered in the widest range of end configurations available. Rated up to 4,000 psi (28 MPa), the No-Skive, four-wire spiral 722LT is available in a wide range of sizes and incorporates a patent-pending spiral reinforcement construction that provides longer life in heavy-duty applications compared with standard braided hose. It also uses Parker’s 43 Series fittings, as well as the 71 Series (for size -24). These hoses can be crimped using Parker’s Parkrimp system. www.parkerhose.com
