Parker 721 hose excels in tight spaces
Sep 1, 2004 12:00 PM
The 721 hose from Parker Hannifin Corp's Hose Products Division offers flexibility for high-pressure applications.
Parker's 721 hose meets SAE 100R12, ISO 3862-1, and EN 856 Type R12 specifications. Because of its one-half SAE 100R12 minimum bend radius, users can expect easy installation in tight spaces and less hose used. This hose has a 4,000-psi working pressure in sizes 3/8" through 1" ID; 3,000 psi in the 1¼" ID; and 2,500 psi in 1½" and 2" ID. The 721 can handle various petroleum base hydraulic fluids and lubricating oils, water/oil emulsion and water/glycol hydraulic fluids.
Hose construction includes a neoprene synthetic rubber inner tube surrounded by four spiral layers of high-tensile steel wire reinforcement. An MSHA-accepted black synthetic rubber cover resists oil and weather, while a gray mylar tape layline makes 721 hose easy to identify.
When combined with Parker Parkrimp 71 Series or BW Series fittings, this hose provides superior leak protection. The hose is compatible with Parker's line of crimpers and can be crimped without removing the hose cover due to its No-Skive design.
