Description
Overview:
This genuine Stihl prefilter is a small but important air intake component for two-stroke handheld tools such as hedge trimmers and brushcutters. Made from durable, open‐cell foam filter media, it captures coarse dust and debris before the main air filter, helping to protect the engine and maintain smooth running. Designed for a precise fit on the HL75 and HL75K hedge trimmers, it also fits many other Stihl machines listed below. As an OEM part (OEM No. 4137 124 1500), it ensures reliable sealing and airflow, reducing wear on the carburettor and engine. The green foam pad is easy to replace during routine servicing, supporting consistent performance in dusty garden and site conditions.
Key Features:
- Genuine Stihl replacement prefilter - OEM No. 4137 124 1500 for consistent fit and performance
- Foam prefilter media traps larger particles while maintaining good airflow to the engine
- Helps extend the life of the main air filter and supports steady idling and acceleration
- Protects carburettor and engine internals from abrasive debris in dusty environments
- Simple, tool-free replacement to minimise downtime during maintenance
- Robust construction suited to regular use in gardening, landscaping, and light site work
- Colour-coded green for easy identification during servicing
- Compatible with a wide range of Stihl models for fleet commonality
Typical Applications:
Used during routine servicing or repairs of Stihl hedge trimmers, brushcutters, blowers, and pole pruners operating in dusty or debris‐heavy conditions. Ideal for hedge cutting, grass trimming, grounds maintenance, and general landscaping where fine plant matter and dust can quickly clog intake systems.
