Continental Contitech NPK-4K038-050-MMS High Pressure Hose

Product Description

The CONTINENTAL CONTITECH NPK-4K038-050-MMS is a 50-foot nitrile high-temperature, high-pressure hose engineered for demanding fluid transfer applications in trade and industrial settings. Built with a 3/8-inch inner diameter and 0.69-inch outer diameter, this hose handles pressures up to 4,000 psi and operates across a temperature range of -20 to 250 degrees F. The nitrile construction delivers strong resistance to oils, fuels, and hydraulic fluids. Fittings are configured as male rigid on one end and male swivel on the other, simplifying installation in tight or fixed-connection plumbing and hydraulic runs. Licensed plumbers, HVAC technicians, and hydraulic system specialists are the primary installers.

This hose is suited for high-pressure fluid transfer in commercial and industrial environments where oil resistance and elevated temperature performance are required. The 50-foot length accommodates longer runs without field splicing, making it a practical choice for equipment service lines, hydraulic circuits, and trade mechanical systems where flexible, high-rated hose connections are needed. The male rigid by male swivel end configuration assists in reducing torque stress during makeup and in service.

Key Features

• 4,000 psi maximum working pressure for high-demand hydraulic and fluid transfer service
• Nitrile tube construction provides resistance to oils, fuels, and petroleum-based fluids
• Operating temperature range of -20 to 250 degrees F for high-temperature environments
• 3/8-inch ID by 0.69-inch OD for precise flow and fitment in standard hydraulic lines
• 50-foot continuous length reduces the need for intermediate couplings
• Male rigid by male swivel fittings allow rotational makeup to minimize torsional stress

Compatibility

Designed as an OEM-style replacement or new-installation hose for high-pressure hydraulic and fluid transfer systems requiring a 3/8-inch male rigid by male swivel connection rated to 4,000 psi.

Installation Notes

Installation should be performed by a licensed plumber, hydraulic technician, or qualified mechanic familiar with high-pressure fluid systems. Depressurize and bleed the hydraulic or fluid circuit fully before disconnecting or connecting hose ends. Inspect fittings and seat surfaces for damage prior to makeup, and do not overtighten the swivel end beyond hand-snug plus the manufacturer-recommended turns for the fitting type. Route the hose to avoid sharp bends, abrasive contact, and heat sources that exceed the rated operating temperature.
