2297194 7X2825 Hydraulic Cylinder Seal Kits LOADER C.A.T EXCAVATOR PTFE NBR

What distinguishes the 2297194 7X2825 PTFE-NBR Hydraulic Cylinder Seal Kits FOR LOADER C.A.T EXCAVATOR is their advanced PTFE-NBR dual-material structure and user-centric design. Each kit comes with a complete set of seals—piston seals, rod seals, wiper seals, and backup rings—made from a high-performance mixture of pure PTFE and nitrile butadiene rubber (NBR). This composite combines the best properties of both materials: PTFE’s excellent chemical resistance and low friction, along with NBR’s strong elasticity and oil resistance. It stands up to abrasion, harsh fluids, and extreme temperatures (ranging from -50°F to 375°F), making the kits suitable for scorching deserts, freezing cold regions, and all environments in between. Besides, the dual-material seals reduce energy loss in the hydraulic system, improving the loader excavator’s fuel efficiency and overall operational flexibility.
