Hydraulic Breaker Seal Kit

If your hydraulic breaker’s impact power drops or it starts leaking hydraulic fluid, you’ll stop your work. A breaker’s hitting force totally depends on steady hydraulic pressure, and that pressure relies a lot on the seal kit. FridayParts has tough, durable seal kits for hydraulic breakers to get your equipment back in high performance.

Components of the Hydraulic Breaker Seal Kit

Our comprehensive seal kits are for a complete and reliable overhaul. While contents vary by model, a typical kit includes:

O-Rings & Backup Rings: Create a secure seal at static and dynamic interfaces and prevent extrusion under high pressure.
Piston Seals: Ensure hydraulic pressure is effectively converted into striking force by sealing the piston head.
Rod Seals: Prevent hydraulic fluid from leaking out along the moving piston rod.
Wiper Seals (Dust Seals): Prevent dirt, dust, and moisture from entering the hydraulic system.
Buffer Seals: Absorb pressure spikes to protect the main rod seal from damage, extending its life.
Wear Rings / Guide Rings: Prevent metal-to-metal contact between moving parts, ensuring smooth operation and reducing wear.
