Replacement Oil Dipstick O‑Ring – Harley FLST & FXST 2000‑2005 – Repl. OEM 11345 – Made in Taiwan (sold each)

OVERVIEW

This direct-replacement O-ring restores the critical seal between the oil dipstick and its mounting tube on Harley-Davidson Softail motorcycles. Engineered to meet factory dimensions, it prevents fluid seepage and maintains consistent internal crankcase pressure during operation. Constructed from a specialized rubber compound, the component delivers long-term reliability for routine maintenance cycles.

ENGINEERING & PERFORMANCE

Machined to exact OEM specifications, this gasket seats securely against the dipstick assembly to eliminate oil leakage and preserve proper transmission and oil tank pressure. The selected rubber formulation provides sustained resistance to elevated engine temperatures while preventing swelling or permanent deformation under repeated thermal cycles. Acting as a straightforward factory-spec swap, it reinstalls without modification and returns the sealing interface to standard operating parameters.

WHY HARLEY RIDERS CHOOSE THIS

Riders rely on this replacement because a failing dipstick seal frequently results in persistent oil drips that soil chassis components and attract abrasive debris. The precision-molded rubber design matches factory tolerances, effectively blocking fluid escape and keeping foreign contaminants away from the transmission and main reservoir. Installation follows a standard removal sequence without requiring specialized tools or calibration adjustments. This targeted fix reliably restores system integrity on 2000 through 2005 Softail models where aging seals naturally compress and fail over extended service life.
