Schwing Hydraulic Oil Resevoir Cap

Schwing Hydraulic Oil Resevoir Cap

This is a hydraulic reservoir filler and breather cap, designed for use on heavy equipment like concrete mixers and pumps. The cap allows for two-way air flow, equalizing pressure in the hydraulic tank as fluid levels rise and fall during system operation. Its internal filter prevents airborne contaminants like dust and dirt from entering and compromising the hydraulic fluid, which is critical for protecting sensitive components like pumps and valves. Constructed from zinc-plated steel for corrosion resistance, this cap is a necessary maintenance part for ensuring the longevity and efficient operation of the hydraulic system.

Key Features

• Allows hydraulic reservoir to breathe, equalizing pressure during operation.
• Filters incoming air to prevent dust and debris from contaminating hydraulic oil.
• Zinc-plated steel construction for durability and corrosion resistance.
• Ribbed/fluted cap design for easy grip during installation and removal.
• Commonly features a 3/4" NPT threaded connection.
