K-Tech Shock Absorber Oil Seal (OS-16-28-5) - 16.00x28.00x5.00mm Showa (Single)

Factory-standard reliability for high-pressure systems. The K-Tech Shock Absorber Oil Seal is a precision-engineered internal component designed as a direct replacement for your original 16mm Showa equipment.

Modern rear shock absorbers operate under immense thermal loads and nitrogen pressure. A compromised seal leads to damping fade, aeration, and loss of control. This seal is manufactured to K-Tech’s exacting standards to provide a robust internal barrier against oil leaks.

By utilizing high-grade materials, it offers a perfect fit and low-friction interface with the 16mm shock shaft, preserving the plush yet responsive damping feel that Showa suspension is known for.
