Parker CAP.1730.40.5 Nonmetallic Breather 10 Micron

Product Description

The PARKER CAP.1730.40.5 is a nonmetallic breather filter designed to allow controlled airflow into hydraulic reservoirs, gearboxes, and other fluid-power enclosures while filtering out airborne particulates. With a 10-micron rating, this breather captures fine contaminants before they enter the fluid system. The body is constructed from nitrile and nylon, and the cap is steel, giving it durability in typical industrial and mobile equipment environments. It mounts from the top of the reservoir or housing and has an outside diameter of 3 inches and an overall length of 6.04 inches. Weighing 0.5 pounds, it is a direct-fit service item handled by hydraulic technicians and fluid-power mechanics.

This breather is suited for use on hydraulic reservoirs, gearboxes, and fluid storage tanks in industrial, agricultural, and mobile equipment applications. Top-mount installation makes it accessible for routine service intervals. The 10-micron filtration level is appropriate for systems requiring clean ingressed air to protect sensitive hydraulic components and seals. It is rated for a maximum working pressure of 5 psi and a maximum working temperature of 195 degrees F, covering a wide range of standard fluid-power operating conditions.

Key Features

• 10-micron filtration rating removes fine airborne particulates from ingressed air
• Nonmetallic nitrile and nylon body resists fluid exposure and corrosion
• Steel cap provides mechanical protection at the top-mount entry point
• Maximum working temperature of 195 degrees F suits most industrial fluid-power applications
• Maximum working pressure of 5 psi supports typical reservoir breathing requirements
• Top-mount design allows straightforward installation and field replacement

Compatibility

Designed as an OEM-style replacement or service breather for hydraulic reservoirs, gearboxes, and fluid-power enclosures requiring a 3-inch top-mount breather with 10-micron filtration.

Installation Notes

Installation is typically performed by hydraulic technicians or fluid-power mechanics. Before replacing the breather, relieve system pressure and allow the reservoir to cool if the fluid is at operating temperature. Ensure the mounting port is clean and free of debris before seating the new breather. Follow equipment manufacturer guidelines and applicable fluid-power service standards for torque and fitment procedures.
