Valve Stem Seals

When selecting the correct Valve Stem Seals, it's essential to consider factors such as compatibility with your engine's specifications, material composition, and quality. Choose valve seals that are designed specifically for your engine type and model to ensure proper fitment and performance. Additionally, opt for high-quality seals made from durable materials to withstand the rigors of engine operation and maintain optimal sealing over time.

JEGS offers a comprehensive selection of Valve Stem Seals designed to meet the needs of automotive enthusiasts and engine builders alike. Our inventory includes valve seals for various engine applications, including small block Chevy (SBC) engines, as well as seals in different materials and configurations to suit different performance requirements and preferences.

Usually made from rubber or silicone, valve stem seals are very important to oil control. They are located at the top of the valve stem and help ensure a tight seal between the valve stem and valve guide to prevent engine oil from migrating to the combustion chambers. As an oil seal, valve stems are an indispensable part of preventing oil consumption and enhancing engine performance.

This is where you can find valve stem seal replacements from top brands like COMP Cams, Fel-Pro, Dart and Howards Cam, along with a handy specialized installation tool from COMP Cams (this billet aluminum tool is designed for .500” and .531” PTFE valve stem seals). Some models of valve stem seals include a spring-loaded wiper that helps remove excess oil from the valves. Like everything else, the materials for valve stem seals have evolved quite a bit over time. While almost all valve stem seals were once made from rubber or silicone, popular materials now include nitrile, Viton or FKM (usually clad in a metal casing for extra strength) and Teflon or PTFE. PTFE and Viton in particular provide better heat resistance.

Worn valve stem seals will exhibit all the classic symptoms of oil consumption, including blue oily-smelling smoke (especially at startup or on acceleration), poor performance, rough idle and fouled spark plugs. While installing valve stem seals is a pretty involved job, the seals themselves come at an affordable price. Replacing these parts should be a must for any valve job or engine overhaul.
