Parker’s 472LT and 722LT hose lines designed For industry’s coldest conditions with high working pressures.

Parker Hannifin introduced its 472LT and 722LT lines of hoses engineered to work in temperatures as low as -70°F (-57°C). Specifically designed, tested and field-proven for high-impulse, heavy-duty applications, Parker’s 472LT and 722LT hoses are intended for mining, drilling and construction equipment found commonly throughout northern Canada and the Arctic Circle.

Available in -4 to -16 sizes, the No-Skive, two-wire braided 472LT hose is rated for 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 sizes from -6 to -24, and incorporates a patent-pending spiral reinforcement construction that provides longer life in heavy-duty applications compared to standard braided hose, the company says. It also uses Parker’s 43 Series fittings, as well as the 71 Series (for size -24).

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).
