Parker 5561 Nonmetallic Breather 10 Micron Top Mount

Product Description

The PARKER 5561 is a 10-micron nonmetallic breather designed to filter airborne contaminants from entering hydraulic reservoirs, gearboxes, and fluid storage tanks during normal pressure and vacuum breathing cycles. Built with a nitrile and nylon body and a steel cap, it provides durable filtration in demanding industrial environments. The 10-micron rating captures fine particulate before it reaches the fluid system, helping maintain fluid cleanliness and extend component service life. Licensed mechanics and industrial maintenance technicians install this unit in top-mount configurations on reservoirs and tanks where vented breather protection is required.

The PARKER 5561 is suited for hydraulic reservoirs, gear housings, and fluid storage tanks in industrial, mobile equipment, and manufacturing applications. Its top-mount design fits standard reservoir ports and filler necks where a threaded or press-fit breather is needed. The unit handles operating temperatures up to 90 degrees C, making it appropriate for warm-running systems such as those found in mobile hydraulics and industrial machinery. It is sold individually and ships as a single unit.

Key Features

• 10-micron filtration rating captures fine airborne particulate during reservoir breathing cycles
• Nonmetallic body construction using nitrile and nylon for corrosion resistance and chemical compatibility
• Steel cap provides mechanical protection to the filter element
• Top-mount configuration fits standard reservoir and gearbox vent ports
• Rated for continuous use up to 90 degrees C maximum working temperature
• Compact form factor with 83 mm outside diameter and 153.5 mm overall length

Compatibility

Designed as an OEM-style replacement breather for hydraulic reservoirs, gearboxes, and fluid storage tanks requiring a top-mount, 10-micron nonmetallic breather element.

Installation Notes

Installation is typically performed by industrial maintenance technicians or hydraulic system mechanics. Relieve all system pressure and shut off the equipment before removing the existing breather. Ensure the mounting port threads or bore are clean and undamaged before installing the new unit. Follow applicable equipment OEM guidelines and any site-specific fluid-system maintenance procedures during service.
