Huilian SB131 Membrane — Reliable Excavator Breaker Seal
Overview
The Huilian SB131 membrane is a precision-engineered seal designed for hydraulic breakers used in excavators. Manufactured by Huilian — a trusted OEM supplier since 2005 — this membrane delivers reliable sealing performance to keep your breaker operating efficiently and reduce costly downtime.
Key Features

Each membrane is molded to strict dimensional tolerances to ensure a secure, leak-free fit. Precise fitment reduces oil loss and maintains consistent breaker power.
Performance Benefits
- Reduces leakage and pressure loss
- Improves hydraulic efficiency and impact consistency

Compatibility & Applications
The SB131 membrane is compatible with a wide range of hydraulic breaker models and is commonly used in construction, demolition and mining equipment. If you need model-specific fitment, Huilian’s technical team can confirm compatibility for your breaker.
Installation & Maintenance
Installation is straightforward for experienced technicians. Always inspect the membrane and seating surfaces for wear or damage before fitting. Use recommended lubricants and follow breaker manufacturer guidelines. Regular checks help spot early wear and prevent failures.
