3315409702 Hydraulic Breaker Seal Kit for Epiroc & Atlas Copco SB702 Hammer Repair | Heavy-Duty Cylinder Rebuild Solution

Product Overview

Maintain optimal strike frequency and prevent costly hydraulic pressure losses with our premium Hydraulic Breaker Seal Kit (Part Number: 3315409702 / 3315 4097 02).

Designed to match or exceed OEM specifications, this heavy-duty overhaul kit is engineered specifically for Epiroc and Atlas Copco SB702 & SB702 Scaler hydraulic breakers (105mm working tool diameter). Built to handle severe impact loads, rapid cycling, and continuous hydraulic surges, it provides superior sealing reliability for demanding rock breaking, trenching, and tunneling operations.

Key Features & Benefits

• High-Performance Composite Materials

  Manufactured using high-grade Polyurethane (PU/TPU), heat-resistant NBR rubber, and low-friction PTFE compounds engineered to resist extrusion, hardening, and wear under continuous high-frequency pressure spikes.

• Zero-Leak Hydraulic Efficiency

  Precision-molded tolerances guarantee an exact drop-in fit. Eliminates internal oil bypass, prevents piston power loss, and controls cylinder drift during heavy vertical or horizontal operation.

• Complete Cylinder Service Solution

  Includes a fully matched seal set—piston seals, step seals, buffer rings, dust wipers, and high-pressure O-rings—enabling a complete single-service hammer overhaul.

• Superior Environmental Protection

  Reinforced dust wipers actively prevent abrasive gravel, rock dust, and moisture from penetrating the internal cylinder chamber, extending the operational life of the piston and bushings.
