The new 472LT and 722LT hoses from Parker Hannifin Corporation are engineered to work in temperatures as low as -70°F (-57°C) – the industry’s lowest temperature rating – while maintaining high performance, thereby helping to reduce downtime and increase productivity for machines that operate in extreme-cold environments. 

Specifically designed, tested and field-proven for high-impulse, heavy-duty applications, Parker’s 472LT and 722LT hoses are ideal for mining, drilling and construction equipment found commonly throughout northern Canada and the Arctic Circle. They are also suited for snow groomers, side booms, snowmaking machinery and cold storage applications in general. Immediately available in -4 to -16 sizes, 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 (-6 to -24), and incorporates a patent-pending spiral reinforcement construction that provides longer life in heavy-duty applications compared to 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 with the industry’s easiest-to-use crimping system, Parker’s Parkrimp system.  Both hoses feature a half-bend radius, and are rated for applications with an operating temperature range of -70°F to 212°F (-57°C to 100°C).
