Brand New ZF 0634304049 Heavy Equipment Hydraulic O-Ring
The ZF 0634304049 (0634.304.049) O-Ring is a genuine OEM elastomeric sealing element engineered specifically for heavy equipment transmissions, hydraulic control blocks, axles, and powershift drive systems manufactured by ZF Friedrichshafen AG.
Major Applications & Drivetrain Assemblies
· Powershift & Ergopower Transmissions: Used across automated and manual transmission housings to seal internal hydraulic fluid passages and valve control blocks.
· Axle Housings & Differentials: Found in multi-stage planetary axles and steering rigid axles utilized by Hitachi, John Deere, and Hyundai heavy equipment lines.
Thank you for choosing SPARKLING MACHINERY.
The ZF 0634304049 O-ring is molded to exact cross-sectional dimensions using high-tier elastomer compounds (such as Nitrile/NBR or Viton/FKM). Designed to operate reliably under high continuous operating pressures and elevated oil temperatures, it creates a tight physical barrier between flat mating surfaces, fluid ports, and internal valve bodies within ZF heavy equipment assemblies.
