Description
Overview:
The Piston O'Ring 35 mm (1.38 in) is a genuine JCB sealing ring designed for hydraulic systems, including the JCB HM25 Hydraulic Breaker. Made from durable rubber suited to hydraulic use, it creates a tight seal around the piston to prevent fluid leakage and maintain working pressure. This helps protect internal components, improves efficiency, and supports smoother operation in demanding site conditions. As an OEM component (OEM No. 929/05330), it matches the original specification for fit and performance, reducing the risk of compatibility issues. Ideal for service and repair tasks on compact breakers and similar hydraulic tools, this O'Ring supports anti-vibration characteristics within the assembly and is a dependable choice for tradespeople and DIY users who need reliable sealing in tough environments.
Key Features:
- Genuine JCB part for assured compatibility and fit on HM25 hydraulic breaker assemblies
- 35 mm diameter (1.38 in) for the correct piston sealing interface
- Robust rubber construction engineered for hydraulic service conditions
- Helps prevent leaks, maintaining pressure and system efficiency
- Supports anti-vibration performance within the piston and housing
- Stable sealing under typical operating temperatures and pressures of breaker systems
- Consistent sizing to OEM standard for predictable installation and performance
- Straightforward to replace during routine maintenance or overhaul
- Helps extend service intervals by protecting internal components from fluid bypass
- Suitable for use in demanding site and workshop environments
Typical Applications:
Used during repair and maintenance of the JCB HM25 Hydraulic Breaker to restore piston sealing integrity. Suitable for hydraulic breaker pistons and comparable sealing points where a 35 mm O'Ring is specified. Helps maintain impact performance, prevents oil loss, and supports reliable operation on construction, demolition, and utilities work.
