FEL-PRO VALVE STEM OIL SEALS HONDA D/B/F/H/K-SERIES
Fel-Pro engineers analyze the OE design for every application. The OE design is tested and benchmarked. Based on the analysis, we determine the material used, considering the durometer (relative hardness) of the rubber, temperature requirements (both extreme heat and extreme cold), resistance to common oil types, tear-resistance and leak rate.
This type of analysis makes one thing clear, not all valve stem seals are created equal. Visually, a lower-quality seal may look very similar to a high-quality seal that’s appropriate for a given engine platform. However, a lower-quality seal with insufficient heat-resistance will harden and crack prematurely and will not work as intended.
You can count on Fel-Pro to use the right material for each application. Fel-Pro uses a variety of materials including nylon, PTFE, rubber, steel and synthetic rubber or some combination of these. FKM, fluoroelastomer, is used in many Fel-Pro valve stem seals for hotter-running, late-model vehicles. It is often combined with a metal jacket or covering that totally surrounds the FKM positive seal. FKM offers excellent resistance to both heat (up to 450°F) and abrasion.
On some applications, the valve stem seals are interchangeable between the intake and exhaust valves and will look exactly the same. On applications which use different seals on the intake and exhaust valves, due to needing higher temperature material on the exhaust side or different design, the seals will be bagged and labeled appropriately.
An installation tool is included in Fel-Pro valve stem seal (VS) sets. This tool is a thin plastic sleeve which is placed over the tip of each valve stem during installation. It protects the inner lip of the seal from damage by the lock grooves in the valve stem.
