The Epiroc EC 150 T piston is the heart of your breaker. Every blow your hammer delivers starts with this part. When the piston wears, scores or cracks, you lose impact energy, seals fail faster and the cylinder can be damaged. Our MERIT replacement piston, part number 3363112401, brings your Epiroc EC 150 T hydraulic breaker back to full working power. It is matched to EC 150 T breakers such as serial number DEQ212317.
The EC 150 T is designed for carrier machines of 25 to 40 tonnes. These breakers work long shifts in quarries, demolition and trenching. A piston that cannot handle that load will not last.

Why 4340 alloy steel?
4340 is a nickel-chromium-molybdenum steel. It combines high strength with high toughness, so it resists both wear and fatigue cracking. That matters for a part that takes hundreds of impacts per minute.
- High fatigue strength for continuous hammering
- Good toughness, so it resists cracking under shock loads
- Precision-ground running surfaces to protect seals and the cylinder bore
- Seal and guide grooves machined to match the original part geometry
3000 operating-hour warranty
Every Epiroc EC 150 T piston we supply carries a 3000 operating-hour warranty. You get a clear, measurable promise instead of a vague “quality” claim. Contact us with your hour-meter reading and photos if you need support.
Delivery to workshops in Oman and UAE
We ship from our base in Turkey directly to your repair workshop in Oman or the United Arab Emirates. Each piston is treated against corrosion and packed in a reinforced transport case, so it arrives ready to install.
Signs your EC 150 T needs a new piston
- Weaker blows or a lower blow rate than normal
- Oil leaking past the seals soon after a seal kit change
- Scoring, pitting or discoloured bands on the piston surface
- Cracks at the impact face or near the grooves
Replace the seal kit together with the piston. A worn seal on a new piston, or a new seal on a scored piston, shortens the life of both. See our EC 150 T seal kit.
