A new addition has joined Parker Hannifin’s high-pressure hydraulic hose product line. The R50TC/R56TC ParLock Multispiral hoses for working pressures from 50 to 56 MPa were introduced at industrial technology trade fair Hannover Messe 2019.

Designed for large mobile hydraulic equipment and agricultural machines, the hose excels in extremely dynamic, high-pressure applications and exceeds ISO 3862 Type R15 specifications, according to the manufacturer. R50TC/R56TC hoses withstand both high internal strain as well as frequent external forces caused by motion of the hose in routine operations. The ParLock high-performance skive system is used to attach the hoses to fittings, ensuring high reliability in heavy-duty functions where safety is crucial.

R50TC/R56TC hoses feature a rugged synthetic rubber inner tube, reinforced with four or six high-tensile steel wire spirals and encased in a highly abrasion resistant, MSHA-approved, synthetic rubber cover. The hoses handle a variety of working fluids including petroleum and water-glycol-based fluids, lubricating oils, water and air. Working temperatures range from -40° C to 100° C (maximum water temperature: 85° C; maximum air temperature: 70° C) and minimum burst pressure is rated at 200 MPa to 224 MPa.

Reliability is ensured by subjecting the hoses to one million test cycles at 120% working pressure. Approval has been granted for use with 8,000 psi flanges in straight, 45° and 90° arrangements.
