HIGH PERFORMANCE PRO-X Control Cables feature: "Armored" Core -Highly efficient "armored" core technology is the best in the industry. Stainless steel flat wire swaged over stainless steel stranded cable and burnished to a smooth, close tolerance finish, provides high flexibility and incredible strength. Inner Liner- Specially processed polymer liners minimize friction for maximum efficiency. The inside diameter is precisely controlled to minimize lost motion and premature wear, problems that seem to plague most "splined" or "grooved" liners. Conduit - A "full complement" of reinforcing wires are placed in a long lay pattern to protect the liner and inner core. The close tolerances achieved between the cable core and conduit result in minimal deflections during cable operation, assuring precise controlling action to the operator. Outer Jacket -Heavy duty, high density non-hydroscopic polymer jacket is extruded onto the conduit for maximum cable strength and abrasion resistance. End Fittings -300 series stainless steel and nickel-plated brass are used throughout to ensure maximum corrosion resistance. Seals & Boots -Durable polymer seals are used to prevent moisture and contaminants from entering the cable.
