Description
Product Overview
The Fel-Pro Deflector Valve Stem Seal (model SS5112) is a precision‑engineered component designed to restore the sealing integrity of your engine’s valve train. Crafted from a proprietary deflector (umbrella) material, the seal offers superior resistance to heat, oil, and combustion gases. Its round shape and vehicle‑specific fit ensure that it mates perfectly with the OEM valve stem geometry, eliminating gaps that can lead to compression loss or oil leakage. At just 0.317 ounces and measuring 3.4 x 3.4 x 1.2 inches, the seal is lightweight yet robust, meeting the rigorous standards set by Fel-Pro engineers.
Usage
This valve stem seal is intended for use in both passenger cars and light trucks that require a deflector‑type seal. Ideal for routine maintenance, rebuilds, or performance upgrades, it fits a wide range of domestic and foreign nameplate vehicles. Install the seal when you notice symptoms such as reduced engine power, increased oil consumption, or audible valve stem noise. The included installation tool protects the inner lip of the seal during placement, reducing the risk of damage and ensuring a consistent seal across multiple service events.

FAQ
What vehicles are compatible with this seal?
The seal is engineered for a broad range of passenger cars and light trucks. Compatibility is determined by the OEM part number SS5112, which matches the original Fel-Pro deflector seal used in many domestic and foreign models. Consult the fit guide or contact customer support with your vehicle’s make, model, and year for confirmation.
How does a deflector seal differ from an O‑ring seal?
A deflector seal features an umbrella‑shaped lip that redirects oil and combustion gases away from the valve stem, providing superior protection in high‑temperature environments. O‑ring seals rely on a simple circular cross‑section and may not offer the same level of oil blow‑by resistance under extreme conditions.
Can I install the seal myself?
Yes. The package includes a specialized installation tool that safeguards the seal’s inner lip. Follow the service manual’s torque specifications and ensure the valve stem is clean before placement. If you are unfamiliar with valve train work, professional installation is recommended.
Is this seal a direct OEM replacement?
Absolutely. The part carries the OEM number SS5112 and matches the original specifications set by the vehicle manufacturer. Using a genuine Fel-Pro seal maintains warranty compliance and ensures optimal engine performance.
What warranty does Fel-Pro provide?
Fel-Pro offers a limited warranty covering defects in material and workmanship for a period of one year from the date of purchase. The warranty does not cover damage caused by improper installation or misuse.
