5. FAQ

Q: What's the special of the gasket 17M-22-25141 ?

A: The 17M-22-25141 gasket is typically made of a heavy-duty, high-density compressed non-asbestos fiber (CNAF), often bonded with a synthetic rubber nitrile binder (like NBR).Because the "17M" prefix in Koma's part numbering system generally denotes components for their final drive, steering clutch, or transmission groups (commonly found on medium-to-large bulldozers like the D65, D85, and D155 series), the gasket material is specifically engineered to handle harsh powertrain environments.Here is why this specific material blend is used for this gasket:Oil and Fluid Resistance: The nitrile/synthetic rubber binder prevents heavy powertrain oils, gear lubricants, and hydraulic fluids from degrading or eating through the gasket.High Temperature Stability: It can easily withstand the continuous operating temperatures 100 to 120, generated by heavy-duty gears and friction clutches.Crush and Torque Retention: Powertrain casings bolt together with high torque. This material is designed to compress just enough to seal the microscopic imperfections in the metal faces without tearing, squeezing out, or losing bolt tension over thousands of operating hours.If you are looking at an aftermarket replacement version of this gasket, it might also appear as a dark gray or green fibrous sheet material.

Q: What is the function of this gasket set?
A: It is a comprehensive static sealing kit, designed for high-pressure applications like cylinder liners or pump housings. The elastomer O-rings provide the primary fluid-tight seal, while the PTFE backup rings prevent O-ring extrusion into gaps under extreme pressure, ensuring long-term reliability.

Q: What is the structure of this gasket set?
A: It is a matched set of circular rings, with different cross-sections and profiles. The elastomer rings are flexible and compressible, while the PTFE rings are rigid and flat. They are designed to work together in pairs within a single seal groove.

Q: Where is this gasket set installed?
A: It is installed in a dedicated gland groove on components like cylinder liners or pump bodies. Typically, the PTFE backup ring is placed first, followed by the elastomer O-ring, to form a high-pressure static seal between the liner and the housing.
