Everdigm EHB Series Seal Kit For Hammer Resealing Oil Control And Dust Protection

Everdigm EHB Series Seal Kit For Hammer Resealing Oil Control And Dust Protection

Product Introduction

The Everdigm EHB Series Seal Kit For Hammer Resealing Oil Control And Dust Protection is a maintenance repair kit designed for excavator-mounted hydraulic breaker hammers. It is suitable for Everdigm EHB Series hydraulic breakers, including common models such as EHB02, EHB04, EHB05, EHB13, EHB17, EHB20, EHB25, EHB30, EHB40, and EHB50.

A seal kit is one of the most frequently replaced repair parts in a hydraulic breaker. It is used to seal hydraulic oil, control internal pressure, prevent dust and dirt from entering sensitive areas, and protect moving components such as the piston and cylinder. During concrete demolition, road repair, trenching, quarry work, asphalt removal, and general construction breaking, the hammer works under high pressure, strong impact vibration, oil temperature changes, and heavy dust conditions.

When the seal kit becomes worn, aged, hardened, cracked, or damaged, the hydraulic breaker may show oil leakage, weak impact, slow response, unstable frequency, pressure loss, abnormal heat, contaminated hydraulic oil, or fast piston and cylinder wear. Replacing the seal kit in time helps restore sealing performance, reduce oil waste, protect internal parts, and keep the breaker working more smoothly.

This product is an aftermarket replacement seal kit compatible with Everdigm EHB Series hydraulic breakers. The Everdigm name and EHB model references are used only for compatibility identification.

Material

Our Everdigm EHB Series hydraulic breaker seal kits are supplied with different sealing materials according to sealing position, pressure level, oil temperature, working environment, and customer requirements. Common materials include FKM, PU, NBR, PTFE, rubber, O-rings, oil seals, dust seals, backup rings, and support rings.

FKM is often used in positions requiring oil resistance, heat resistance, and chemical stability. It is suitable for hydraulic breaker working conditions where the seal must resist hydraulic oil and temperature changes.

PU is widely used for high-pressure and dynamic sealing positions. It has good elasticity, wear resistance, and pressure resistance, making it suitable for moving areas inside the hammer.

NBR is a practical oil-resistant rubber material used in many hydraulic sealing positions. It offers good general sealing performance and cost efficiency.

PTFE has low friction and good chemical resistance. It is often used for backup rings, guide rings, and areas that require smooth movement and stable sealing support.

Different sealing positions inside the breaker need different materials. A correct material combination helps improve sealing stability and reduce repeated leakage problems.

Product Features

The main feature of the Everdigm EHB Series seal kit is complete hammer resealing support. It is not only used to stop visible oil leakage, but also helps maintain internal pressure and prevent dust contamination during long working hours.

The seal kit works together with the piston, cylinder, front head, back head, diaphragm, accumulator system, and hydraulic oil circuit. When the seals are correctly installed and properly matched, hydraulic oil can stay inside the working chamber more effectively, and the breaker can maintain better impact output.

Accurate size is very important. If the seal is too large, too small, too hard, too soft, or incorrectly matched, installation may be difficult and leakage may continue after repair. A suitable seal kit helps reduce internal oil loss, protect the piston surface, reduce cylinder wear, and improve hammer service life.

Dust protection is also important for hydraulic breaker operation. Breakers often work in concrete dust, stone powder, soil, and road construction debris. Dust seals help reduce contamination entering the breaker, protecting the internal sealing area and reducing abnormal wear.

This seal kit can be supplied for regular maintenance, urgent oil leakage repair, hydraulic hammer rebuild, workshop repair service, and spare parts stock. It can also be ordered together with pistons, cylinders, chisels, inner bushes, outer bushes, diaphragms, rod pins, through bolts, side bolts, front heads, back heads, buffers, and wear plates.

Main Advantages

The main advantage of the Everdigm EHB Series seal kit is fast sealing system recovery. When a hydraulic breaker starts leaking oil or losing pressure, replacing the seal kit is often one of the most important repair steps.

For demolition contractors, a reliable seal kit helps the hammer maintain stable impact when breaking concrete slabs, walls, foundations, and reinforced structures. For road repair and municipal work, good sealing performance helps the breaker handle asphalt removal, trenching, curb breaking, and pavement repair. For quarry and stone breaking applications, oil control and dust protection are important for long working hours.

Timely seal kit replacement can also protect expensive internal parts. If worn seals continue working, hydraulic oil leakage may damage the piston, cylinder, diaphragm, accumulator, and other internal components. Dust and oil contamination may also increase wear and shorten the service life of the whole breaker.

For repair workshops and spare parts dealers, seal kits are fast-moving maintenance products. Keeping Everdigm EHB Series seal kits in stock can help customers complete repair work faster and reduce equipment downtime.
