valve oil seal

Valve oil seals belong to one-to-one oil seals, mainly installed on engine valve stems to seal engine oil and prevent oil burning.

effect

Control the amount of oil on the valve stem to protect lubrication without entering the combustion chamber

Prevent oil from entering the cylinder through the valve stem, avoid burning oil and emitting blue smoke

Block dust and impurities from entering the engine interior

feature

Small size, good precision, strict material requirements

High working temperature, exposure to high-temperature engine oil and exhaust gas, requiring aging resistance and oil resistance

Usually made of FKM or ACM material

Most of them come with a metal frame, which is tightly installed and has good sealing performance

application

Cylinder heads for automobiles, motorcycles, diesel engines, and gasoline engines

Valve mechanisms for construction machinery, generators, and marine engines

Frequently Asked Questions

After aging and hardening, the seal will not be tightly sealed, which is directly manifested as burning engine oil, blue smoke in the exhaust pipe, and increased carbon deposition.
