Parker 937482 Suction Strainer 7 Gpm 3/4 Npt No Bypass

Product Description

The PARKER 937482 is a threaded suction strainer designed for hydraulic and fluid-transfer systems where protecting downstream components from particulate contamination is critical. Rated at 25 LPM (7 GPM) with a maximum flow rate of 30 LPM (8 GPM), this strainer installs directly into a reservoir or suction line via a 3/4-inch NPT port. The stainless steel screen provides reliable filtration without a bypass valve, ensuring flow does not bypass the element under any condition. At 0.33 pounds, the compact unit measures 2.52 inches in diameter and 3.55 inches in length. Hydraulic technicians and fluid-power specialists specify this type of strainer to protect pumps from ingesting debris on the suction side of a circuit.

This strainer is suited for residential and light commercial hydraulic systems, fluid-power equipment, and industrial machinery where NPT-threaded suction-line connections are standard. The no-bypass design is appropriate for installations where unfiltered flow is not acceptable and the system is sized to operate within the rated flow envelope. The 195 degrees F maximum working temperature rating makes it compatible with a range of petroleum-based and synthetic hydraulic fluids used in typical service conditions.

Key Features

• Stainless steel screen for corrosion resistance and durability in hydraulic fluid service
• No-bypass design ensures all flow passes through the screen element
• 3/4-inch NPT threaded port for straightforward inline or reservoir installation
• Rated to 195 degrees F maximum working temperature, compatible with common hydraulic fluids
• Compact form factor at 2.52 inches diameter and 3.55 inches length for tight installations
• Lightweight at 0.33 pounds for easy handling during service

Compatibility

Designed as a direct-fit replacement or new-installation suction strainer for hydraulic and fluid-transfer systems using 3/4-inch NPT suction-line connections operating within a 30 LPM (8 GPM) maximum flow rate.

Installation Notes

Installation is performed by qualified hydraulic technicians or fluid-power mechanics. Depressurize and drain the hydraulic circuit fully before removing or installing any suction-side component. Apply appropriate thread sealant to the NPT threads per the equipment manufacturer and applicable plumbing or fluid-power standards. Because this strainer has no bypass, ensure system flow does not exceed the rated maximum to prevent excessive pressure drop on the suction side of the pump.
