Parker 937495 Suction Strainer with Bypass 92 Gpm

Product Description

The PARKER 937495 is a suction strainer with integral bypass designed for hydraulic and fluid-transfer systems requiring reliable inlet filtration. It filters incoming fluid before it reaches the pump, protecting downstream components from particulate contamination. The strainer body accepts a 2-1/2 inch NPT threaded connection and reaches 10.1 inches in length. The stainless steel screen element handles flow rates up to 92 GPM and withstands working temperatures up to 195 degrees F. The bypass valve opens when differential pressure exceeds 3 psi, preventing pump starvation during cold starts or high-viscosity conditions. Hydraulic technicians and fluid-power mechanics are the primary installers.

This suction strainer is suited for mobile hydraulic equipment, industrial power units, and reservoir-mounted inlet applications where pump protection is required. Its threaded NPT connection simplifies installation into standard pipe manifolds or reservoir bungs. The bypass feature makes it appropriate for systems that operate across a wide temperature range or use fluids that thicken significantly at startup. Both light industrial and heavy-duty mobile applications fall within its typical service scope.

Key Features

• Stainless steel screen material resists corrosion and maintains structural integrity across the rated temperature range
• Integral bypass valve opens at 3 psi differential to protect the pump from starvation
• 2-1/2 inch NPT threaded port fits standard pipe fittings without adapters
• Rated to 195 degrees F maximum working temperature for use with a broad range of hydraulic fluids
• Flow capacity up to 92 GPM supports medium to large hydraulic power units

Compatibility

Designed as an OEM-style replacement or direct-fit suction strainer for hydraulic reservoir inlet applications using standard 2-1/2 inch NPT ported manifolds or reservoir bungs.

Installation Notes

Installation should be performed by a qualified hydraulic technician. De-energize the hydraulic system and relieve all system pressure before removing or installing the strainer. Ensure the reservoir is at a safe fluid level to prevent spillage during installation. Apply appropriate thread sealant to NPT threads per the fluid-system manufacturer guidelines and verify the bypass direction is oriented correctly before startup.
