Description
Overview:
The Piston Ring (each) for Cobra TT Breaker is a genuine Atlas Copco component designed to maintain tight cylinder sealing and engine compression in handheld petrol breakers. Built from durable, wear‐resistant metal and finished to precise tolerances, it sits in the piston groove to create a reliable gas seal, supporting consistent power and efficient running. It is ideal for servicing Atlas Copco breakers such as the Cobra TT and Cobra PROi, replacing worn rings that can cause loss of power and difficult starting. Supplied as a single ring, it matches OEM No. 9234 0000 07 (MPN 9234000007) for correct identification and OE fit. Using the genuine ring helps protect the piston and cylinder from premature wear and keeps your breaker working reliably in demanding site conditions.

- Genuine Atlas Copco part for correct fit and reliability (OEM No. 9234 0000 07; MPN 9234000007)
- Restores and maintains cylinder compression for steady power and impact performance
- Precision-made ring for accurate sealing and reduced blow‐by
- Heat- and wear-resistant metal for long service life in demanding environments
- Direct replacement for the original ring; no modifications when used with the correct piston

Typical Applications:
Used during routine maintenance or engine overhauls of Atlas Copco handheld breakers to replace worn piston rings that lead to hard starting, reduced impact rate, and loss of power. Suitable for high‐hour machines operating on construction sites, roadworks, utilities, and landscaping where dust and heat accelerate ring wear.
