Parker 937483 Suction Strainer Bypass 7 Gpm 3/4 Npt

Product Description

The PARKER 937483 is a threaded-mount suction strainer with an integral bypass, designed for fluid system protection in hydraulic and industrial plumbing applications. Rated at 25 LPM (7 GPM) with a maximum flow of 30 LPM (8 GPM), it filters incoming fluid before it reaches pumps and control components. The 3/4 inch NPT port and stainless steel screen make this unit a durable inline choice for systems operating at low differential pressure. Maximum working pressure is 3 psi and maximum working temperature is 195 degrees F. Licensed plumbers and hydraulic system technicians are the primary installers.

This suction strainer suits residential and light commercial fluid handling systems where pump inlet protection is required. Its 2.67 inch diameter body and 3.55 inch overall length allow installation in tight plumbing runs. The threaded NPT connection simplifies retrofit work on existing piping without the need for flanged adapters. The built-in bypass prevents system starvation if the screen becomes partially blocked, maintaining flow continuity during operation.

Key Features

• Integral bypass valve prevents flow starvation if screen loads up
• Stainless steel screen resists corrosion in wet service environments
• 3/4 inch NPT threaded connection for straightforward inline installation
• Rated to 195 degrees F maximum working temperature
• Compact body at 2.67 inches diameter and 3.55 inches length fits tight spaces
• Maximum working pressure 3 psi, suited for low-pressure suction-side service

Compatibility

Designed as an OEM-style replacement or new-installation suction strainer for fluid systems with 3/4 inch NPT threaded inlets operating at suction-side pressures up to 3 psi and temperatures up to 195 degrees F.

Installation Notes

Installation should be performed by a licensed plumber or qualified hydraulic technician. Shut down and depressurize the system fully before removing or installing any inline strainer. Apply thread sealant appropriate for the fluid service on all NPT connections and verify there are no leaks before returning the system to operation. Consult applicable plumbing codes and system manufacturer guidelines for suction-line strainer placement requirements.
