Parker 937485 Suction Strainer with Bypass 10 Gpm

Product Description

The PARKER 937485 is a threaded suction strainer with integrated bypass, designed for hydraulic and fluid system applications where protecting downstream components from particulate contamination is critical. Rated for a maximum flow rate of 10 GPM (38 liters per minute), it features a stainless steel screen and a 1-inch NPT threaded port for direct inline installation. The bypass function allows fluid to continue circulating when the screen reaches its differential pressure limit, preventing starvation to pumps and actuators. Licensed hydraulic technicians and fluid power specialists typically install this strainer during system assembly or scheduled maintenance intervals.

This strainer is suited for residential and light commercial fluid power systems, hydraulic power units, and pump suction lines where a compact, threaded inline strainer is required. At 2.67 inches in diameter and 5.35 inches in length, it fits standard plumbing envelopes. The 1-inch NPT thread connects directly to common pump inlet ports and fluid reservoir fittings without adapters in most configurations. Its 195 degrees F maximum working temperature rating makes it appropriate for both ambient and moderately elevated fluid temperature environments.

Key Features

• 10 GPM (38 LPM) maximum rated flow rate for consistent performance in light-duty hydraulic circuits
• Integrated bypass valve prevents pump cavitation when the screen is restricted or due for service
• Stainless steel screen construction for corrosion resistance and durability in hydraulic fluid environments
• 1-inch NPT threaded port for direct connection to standard pump inlets and reservoir fittings
• Rated to 195 degrees F maximum working temperature, suitable for moderately elevated fluid temperatures
• Compact form factor at 2.67 inches diameter and 5.35 inches length for tight installation spaces

Compatibility

Designed as an OEM-style replacement or new-installation suction strainer for hydraulic power units and pump suction lines requiring a 1-inch NPT threaded inline strainer with bypass.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power specialist. Depressurize and isolate the hydraulic circuit completely before removing or installing any suction strainer. Ensure the strainer is installed on the suction side of the pump with flow direction matching system design. Verify all NPT thread connections are properly sealed with an appropriate thread sealant compatible with the hydraulic fluid in use.
