The unit handles a maximum flow rate of 19 liters per minute (approximately 5 GPM) and operates at a maximum working pressure of 3 psi. Its stainless steel screen provides durable filtration in demanding service environments. At 2.67 inches in diameter and 3.1 inches in length, it is a compact, inline device suited for space-constrained installations. Licensed mechanics, hydraulic system technicians, and fluid power specialists are the primary installers of this component.\u003c\/p\u003e\n\u003cp\u003eThe PARKER 937481 is used in hydraulic fluid systems where suction-side filtration is required to prevent pump cavitation and contamination ingestion. The 1\/2 inch NPT threaded port allows direct connection to standard NPT-tapped fittings and manifolds. The bypass feature ensures system flow is maintained when the screen reaches its pressure differential limit, preventing pump starvation under high-viscosity or cold-start conditions. This strainer is appropriate for both light industrial and mobile hydraulic applications where a compact, threaded suction filter is needed.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eStainless steel screen construction for corrosion resistance and long service life\u003c\/li\u003e\n  \u003cli\u003eIntegrated bypass protects pump from starvation when screen differential pressure is reached\u003c\/li\u003e\n  \u003cli\u003e1\/2 inch NPT threaded port for straightforward installation into standard NPT fittings\u003c\/li\u003e\n  \u003cli\u003eMaximum flow rate of 19 liters per minute (5 GPM) suitable for low-to-mid flow hydraulic circuits\u003c\/li\u003e\n  \u003cli\u003eMaximum working temperature of 195 degrees F (90 degrees C) supports a wide range of hydraulic fluid types\u003c\/li\u003e\n  \u003cli\u003eCompact form factor at 2.67 inches in diameter and 3.1 inches in length for tight installation envelopes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or service part for hydraulic and fluid power systems requiring a 1\/2 inch NPT threaded suction strainer with bypass at flow rates up to 5 GPM.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified hydraulic or fluid power technician. Depressurize and isolate the hydraulic circuit completely before removing or installing any suction-side components. Apply appropriate thread sealant to NPT threads per system fluid compatibility requirements, and verify all connections are leak-free before returning the system to service. Refer to the equipment manufacturer's service documentation and applicable fluid power safety standards during installation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Flow Rate\u003c\/strong\u003e: 19 liters per minute (5 GPM)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 2.67 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 3.1 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePort Size and Thread\u003c\/strong\u003e: 1\/2 inch NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 3 psi (0.2 bar)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Temperature\u003c\/strong\u003e: 195 degrees F (90 degrees C)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eScreen Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBypass\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMount Type\u003c\/strong\u003e: Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.18 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: PARKER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 937481\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51542911123762,"sku":"937481","price":66.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/54f1fa01114693c57848fe17fe7a3636.jpg?v=1785910681","url":"https:\/\/voomisupply.com\/products\/parker-937481-suction-strainer-with-bypass-4-gpm-npt","provider":"Voomi Supply","version":"1.0","type":"link"}
