Valve Stem Seal Set Fel-Pro Grey 5 Piece SS729421 Vehicle Specific

Description

Product Overview

The Fel-Pro valve stem seal set is a meticulously engineered collection of five round seals designed to meet the exacting standards of modern passenger car engines. Each seal is machined from high‑grade steel, providing a durable, corrosion‑resistant surface that maintains a tight seal against the valve stem under the extreme temperature and pressure cycles typical of internal combustion operation. The set is color‑coded grey to match the OEM aesthetic and is identified by the model number SS729421, ensuring a vehicle‑specific fit for a wide range of domestic and foreign nameplate vehicles. With a compact package measuring 4 x 7 x 1 inches and a total weight of just 4.8 ounces, the set is easy to store and handle during service. The included installation tool protects the inner lip of each seal, preventing damage during the critical installation phase and helping technicians achieve a consistent, leak‑free result every time.

Usage

These valve stem seals are intended for use during routine valve train maintenance, valve stem replacement, or complete engine rebuilds. They are suitable for both gasoline and diesel passenger car engines that require a precise, vehicle‑specific fit. The seals work by controlling oil flow to the valve stem, preventing excess oil from entering the combustion chamber while allowing sufficient lubrication to the valve guide. This balance reduces oil consumption, minimizes smoke emissions, and protects the valve seat from premature wear. The set is ideal for professional automotive repair shops, fleet maintenance facilities, and skilled DIY enthusiasts who demand reliable performance and easy installation. When installed correctly, the seals help maintain optimal engine compression, improve fuel efficiency, and extend the overall lifespan of the valve train components.
