Epiroc Impact Piston 3115212600 for Cop1840hd+ 3115 2126 00 Cop1840 Cop1838he+ Piston Atlas

Impact Piston 3115212600 – Direct Fit for Cop1840hd+ and Cop1838he+ Drills

This Epiroc impact piston 3115212600 is a straight swap for the OEM part in Cop1840hd+ and Cop1838he+ rock drills. It’s machined from heat-treated alloy steel, so it handles repetitive high-impact cycles without giving up early. That means fewer teardowns and less time waiting on parts. At around 10 kg each, it ships from stock—no long lead times.

FAQ
FAQ
Will this piston fit my Cop1840hd+ without modifications?
Yes, if your machine calls for 3115212600 or 3115 2126 00. It also crosses to Cop1838he+ and several other Cop models. Double-check the part number stamped on your old piston—if it matches, this one slides right in.
How does your piston hold up compared to the original?
We use a comparable alloy and heat treatment spec, so hardness and fatigue life track closely with OEM. In practice, most sites see similar service hours before needing a swap, provided seals and alignment are maintained.
How fast can you ship once I place an order?
We keep these in stock. For most destinations it’s 3–7 business days, but we can quote express freight if you’re in a pinch. Drop your address in the inquiry and we’ll give you a firm ETA.
Is there any warranty on aftermarket pistons?
Yes, we stand behind our parts with a standard defect warranty. If something’s off, we replace it. Details depend on region—just ask our team when you order.
Can I use this piston on a non-Epiroc drill?
It’s built to Epiroc/Atlas Copco dimensions. Some other machines with similar specs might accept it, but we recommend staying within the listed models unless you’ve confirmed the cross. Send us your rig details and we can check.
What should I change when I install a new piston?
At minimum, replace seals, guide bushings and any wear rings in the front end. Fresh seals protect the new piston and help keep impact energy where it belongs.
