Our seal kits are made to exact specifications and match OEM standards. A high-quality seal kit is a must for any rebuilt hydraulic hammer. Your seal kit should resist high and low temperatures and perform at its best in all cases. An inferior seal kit can wear out prematurely. Depending on the make and model of your hammer, your set kit may come with various sizes of O-rings, packings, and caps.
