JCB Hydraulic Cap Breather

The JCB Hydraulic Cap Breather (OEM 331/18130) is a replacement hydraulic tank filler cap and breather assembly fitted to compatible JCB construction and telehandling equipment. It provides the access point for filling the hydraulic reservoir while incorporating a breather to allow the tank to vent as the hydraulic oil level and temperature change during machine operation. JCB parts listings identify 331/18130 as a “Cap Filler Breather”.

The breather helps maintain appropriate pressure within the hydraulic reservoir while the cap helps prevent dirt and other contaminants from entering through the filler opening. The assembly is designed for demanding working environments and provides a practical replacement where the original filler breather has become damaged, contaminated or otherwise unserviceable. The assembly has a 305 mm stick length and is listed for JCB telehandlers.

FUNCTION AND OPERATION

• Provides a secure filler point for the hydraulic reservoir.
• Allows the hydraulic tank to breathe as pressure changes during operation.
• Helps prevent external dirt and contamination entering the hydraulic system.
• Supports correct operation of the hydraulic reservoir as oil temperature and level change.
• Replaces a damaged, blocked or missing original filler breather assembly.

IMPORTANT INFORMATION

A clean and correctly functioning hydraulic tank breather is important for maintaining the correct pressure balance within the reservoir and helping protect the hydraulic system from contamination. A blocked or damaged breather should be replaced rather than left in service.

Always check the OEM number and machine model or serial number before ordering to ensure the correct hydraulic filler breather is selected.
