3115336500 杯形密封圈 3115324500 Epiroc RD 22U 前头维修零件 0665100012 O型圈

Cup seals that fit. No surprises.

Front head weeping oil or losing ramp pressure? This is the exact Epiroc cup seal pair and O-ring you need for RD 22U, Cop 1028, and Cop 1132 hammers. Part numbers 3115336500 and 3115324500 drop straight in — same dimensions and material spec as the ones pulled from a factory fresh front head.

The set comes with the 0665100012 O-ring, so you're not chasing a separate gasket at the last minute. If you're doing a teardown on RR11, RR14, or RD 18U, these also cross over directly. No grinding, no modifying — just clean the grooves, lube them up, and torque to the book.

Key Advantages
  • OEM part numbers pulled straight from Epiroc's master list — fit Cop 1028, 1132, RR11, RR14, RD 18U, RD 22U without guesswork.

FAQ
FAQ
Are these seals actually Epiroc or just marked as suitable?
They are Epiroc packaged. Part numbers 3115336500, 3115324500, and 0665100012 come in Epiroc bags with barcodes that trace back to their system.
My front head is from an RD 22U — will the O-ring also fit the flush tube?
0665100012 is the O-ring that seals the front head joint, not the flush tube. If your tube is scored, replace it separately or you'll still lose air.
How do I avoid pinching the cup lips during install?
Wet the cups and bore with clean hammer oil, then push them in square. If you force them dry or at an angle, the lip can fold. An old cup makes a decent drift if you're gentle.
What's the typical lead time if you don't have stock?
Usually 2–4 working days from our supplier's regional warehouse. We'll confirm by email once you send us the part numbers — no payment until we know an ETA.
Can I use these on a Cop 1838?
No — Cop 1838 and its variants take a different cup seal profile (3115238600 or 3115233300). Using these would result in low opening pressure or a cracked cup within hours.
We run Cop 1028 in a high‑altitude mine. Does the material handle cold starts?
Polyurethane stays flexible well below freezing, but let the hammer cycle at low pressure for a minute or two to warm the seals before you collar — same as any rebuild.
