7G9968 7G-9968 White PTFE Back up Seal Dust Seal Hydraulic Cylinder Lift Tift Steering Loader Seal Kit

Version 1 (Material & Anti-Extrusion Focus)

Excavator loader hydraulic cylinder rebuilds frequently specify the white PTFE back-up seal 17G9968 for tilt and steering circuits. The dust seal function integrated with 7G-9968 prevents abrasive particles from entering the rod gland area. When lift cylinder pressures spike, the white PTFE backup ring 17G9968 resists extrusion through clearance gaps. Part number 7G-9968 works alongside the main rod seal to maintain zero leakage during steering articulation. The hydraulic cylinder loader kit containing 17G9968 and 7G-9968 withstands 4000 PSI without permanent deformation. Excavator technicians appreciate that 17G9968 maintains dimensional stability across temperature fluctuations. Every dust seal application using 7G-9968 reduces rod scoring caused by silica contamination. The white PTFE material of 17G9968 offers low friction coefficient for smooth tilt cylinder motion.

Version 2 (Application & Dust Protection Focus)

Heavy equipment workshops rely on 17G9968 as the primary backup seal for loader lift and tilt cylinders. The 7G-9968 dust seal component protects steering cylinder rods from mud and water ingress. When servicing an excavator bucket tilt mechanism, install 17G9968 behind the dynamic seal for extrusion protection. Part number 7G-9968 features a scraper lip design that removes debris during each stroke cycle. The lift steering hydraulic cylinder kit including 17G9968 and 7G-9968 fits standard excavator gland recesses. Field tests confirm that 17G9968 extends seal life by preventing backup ring cold flow. Excavator operators prefer 7G-9968 because it maintains consistent wiper pressure against the rod surface. Always pair 17G9968 with a compatible O-ring to achieve the full sealing system performance.
