Parker DT-370-MSMS-5 Hydraulic Check Valve 8 Gpm

Product Description

The PARKER DT-370-MSMS-5 is a hydraulic control check valve designed to allow flow in one direction while preventing reverse flow in hydraulic circuits. Built from steel with a metal seal, it handles operating pressures up to 5,000 psi and flow rates up to 8 GPM. The compact body measures 1.32 inches in length, 0.75 inches in width, and 0.75 inches in height, making it well suited for space-constrained manifold and inline installations. The 11/16-16 Male Seal-Lok (MSMS) inlet thread provides a leak-resistant connection standard in mobile and industrial hydraulic systems. Licensed hydraulic technicians and fluid power specialists are the typical installers of this component.

This check valve fits inline hydraulic circuits in mobile equipment, industrial machinery, and fluid power systems where directional flow control and pressure retention are required. The Male Seal-Lok thread standard makes it compatible with SAE straight-thread O-ring face seal (ORFS) port configurations commonly found in agricultural, construction, and manufacturing hydraulic systems. Its compact overall envelope allows installation in tight plumbing runs or directly adjacent to valve banks and actuator assemblies.

Key Features

• Rated up to 5,000 psi maximum working pressure for high-pressure hydraulic circuits
• 8 GPM maximum flow rate suitable for medium-duty hydraulic lines
• 11/16-16 Male Seal-Lok (MSMS) thread for leak-resistant SAE ORFS-style connections
• Steel body construction for durability in industrial and mobile equipment environments
• Metal seal material for compatibility with a wide range of hydraulic fluids
• Compact footprint at 1.32 inches overall length for space-constrained installations

Compatibility

Designed as an OEM-style replacement or direct-fit component for hydraulic systems using 11/16-16 Male Seal-Lok threaded inline check valve connections rated to 5,000 psi.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power specialist. Depressurize and de-energize the hydraulic system fully before removing or installing any valve component. Verify thread engagement and O-ring seating on the Male Seal-Lok connection before applying system pressure. Observe all applicable fluid power safety standards and equipment manufacturer torque guidelines for the mating port.
