Parker 50AT120BBPGN20H Hydraulic Filter Assembly 20 Micron

Product Description

The PARKER 50AT120BBPGN20H is a hydraulic filter assembly designed to remove particulate contamination from hydraulic fluid circuits. It uses a 20-micron fiberglass microglass filter media to capture fine particles while maintaining acceptable flow resistance across a wide range of operating conditions. The body is constructed from low carbon steel and aluminum, and the assembly connects via a 1-1/4 inch NPTF threaded port. Operating temperature range spans -40 to 225 degrees F, with a maximum rated pressure of 150 psi. This unit is installed by hydraulic system technicians and millwrights servicing industrial, mobile, or stationary hydraulic power units.

This filter assembly is suited for hydraulic systems requiring inline or return-line filtration with a 1-1/4 inch NPT port connection. Typical applications include industrial hydraulic power units, mobile equipment hydraulic circuits, and stationary machinery where fluid cleanliness must be maintained to protect pumps, valves, and actuators. The nitrile seal material is compatible with standard petroleum-based hydraulic fluids and many water-glycol fluids. The assembly format makes it a direct-install solution without requiring a separate bowl or element sourcing.

Key Features

• 20-micron fiberglass microglass media for fine particulate removal in hydraulic circuits
• Low carbon steel and aluminum body construction for durability and weight balance
• 1-1/4 inch NPTF threaded port for secure, leak-resistant connection
• Nitrile seals compatible with petroleum-based hydraulic fluids
• Wide operating temperature range: -40 to 225 degrees F
• Rated to 150 psi maximum operating pressure

Compatibility

Designed as an OEM-style replacement or new-install hydraulic filter assembly for systems with a 1-1/4 inch NPT port connection requiring 20-micron inline filtration.

Installation Notes

Installation should be performed by a qualified hydraulic technician. Depressurize and de-energize the hydraulic system fully before removing any existing filter or breaking into the circuit. Use appropriate thread sealant rated for hydraulic service on NPTF connections; do not overtighten, as aluminum body components can be damaged by excessive torque. Verify that the replacement assembly flow direction and port orientation match the existing system layout before returning the unit to service.
