The Husqvarna 503597402 Gasket Kit is a genuine OEM component designed for the K1250, K1260, and 3122K power cutters. As a factory-sourced kit, it delivers the exact material grade and sealing geometry specified for these machines, ensuring a proper rebuild without guesswork. DHS Equipment supplies this part to help keep your equipment running at full performance.
Key Features
- OEM Sealing Material Integrity — Genuine Husqvarna gaskets are manufactured to the precise compression ratings and material specifications required for these high-cycle power cutter engines, maintaining correct combustion and fluid sealing.
- Complete Kit Coverage — Includes the full set of gaskets needed for a thorough engine service, so you are not sourcing individual pieces or risk mismatching seal grades.
- Direct Engine Rebuild Fit — Each gasket in this kit matches the original mating surfaces on the K1250, K1260, and 3122K, dropping into position without trimming or adapting.
- Restored Compression and Sealing — Worn or damaged gaskets allow combustion gases and fluids to escape, robbing the power cutter of output and increasing engine wear. Installing this kit restores the correct sealing environment throughout the engine.
- Verified Husqvarna Part Number — Cross-reference 503597402 against your parts diagram to confirm the correct kit for your machine before beginning any rebuild.
A gasket kit contains the full complement of engine sealing components required during a top-end or complete engine rebuild — covering mating surfaces between the cylinder, crankcase, and other critical housings. Gaskets prevent combustion gases, fuel, and oil from escaping between joined components, and their condition directly affects engine compression, power output, and longevity. When gaskets degrade, blow out, or are damaged during disassembly, the engine loses sealing integrity, which leads to rough running, overheating, and accelerated internal wear. Replacing all affected gaskets as a matched set ensures every sealing surface is restored to specification in a single service pass.
