Allentown’s wet-process Steel Bond Hose has a flexible steel ply construction allowing easy handling with a small bend radius, yet is extremely crush resistant. The outer cover is abrasion and weather resistant, and the inner liner is constructed of smooth, synthetic rubber built to withstand the abrasive action of concrete. The Steel Bond Hose is recommended for pressure grouting and other high-pressure applications.

*Contact factory for additional Steel Bond Premium Hose sizes.
**Allentown recommends the use of Hevi-Duty ends for longer service life and safety when pumping at high pressures.

Working pressure is based on minimum burst pressure values per manufacturer’s specification. The appropriate high pressure couplings and weld ends must be used. Values are for current supplied product. Consult Allentown for specific applications. Failure/burst pressures are for new hose when installed and used properly.
