Valve Stem Oil Seal Function:

The Mitsubishi Truck Seal Valves are constructed with a unique seal technology that provides superior protection against unexpected engine damage. This seal technology prevents leakage and is key to promoting effective operation of the truck’s cooling system. The valves are designed to allow for a smooth flow rate, creating minimal wear and tear on the cooling system components.

The Mitsubishi Truck Seal Valves are provided with superior corrosion resistance that ensures long-term performance. The valves feature forward baffles to block the external elements and protect the seals from clogging and premature failure. The double piston design of the valve provides superior leak-proof protection, minimizing potential engine damage.

The Mitsubishi Truck Seal Valves are designed to offer superior performance at an economical price. The valves are designed to support all automotive engines, providing reliable protection against coolant leakage and engine damage. The valves also come with a 12-month warranty, so you can have complete peace of mind when driving your truck.

Types of Valve Stem Oil Seals

Valve stem seals are typically divided into two basic types – single lip and double lip. Single lip seals are the most common type and are made from a single layer of material. They’re designed to be used in unison with a gasket and are often used on engines with high-performance camshafts and valve springs. Double lip seals are more common with larger engines and utilize two layers of material, providing superior sealing capabilities.

Product Identifiers

Valve stem seals are essential for optimal engine performance and emissions. Without proper sealing, fuel and oil can leak into the combustion chamber, resulting in a loss of fuel efficiency and poor engine performance. Additionally, dust, dirt, and other debris can enter the combustion chamber and cause damage to the valves, camshafts, and bearings, drastically reducing the lifespan of the vehicle. Replacing a valve stem seal should be done regularly, as their performance will degrade over time.

Valve stem seals are an important and overlooked component of any engine. Their purpose is to provide a tight seal between the valves and the intake ports, while also preventing dirt and debris from entering and damaging the internal components of your engine. Selecting the right material and size is essential for optimal performance, so ensure that you choose the right valve stem seal for your application.

Valve stem seals are made from a variety of materials, including nylon, PTFE rubber, steel, and synthetic rubber. Sometimes these materials are combined into a single sophisticated design. When synthetic rubber is used, there are three basic types: nitrile, polyacrylate, and Viton.

The most important function
Oil metering to the valve guide / stem interface is the primary function of a valve stem seal, contributing significantly to an efficient and
durable valve train of a combustion engine.
The requirements for each engine differ according to their design
parameters and operating conditions. 

NNK can offer a range of standard valve stem seals, which provide the correct oil metering rate for many applications. This is true for diesel and gasoline applications as well as for intake and exhaust valves.
There are however, applications where the oil metering rate must be adjusted. The oil metering rate can be tuned to the exact requirements of a specific engine by changing defined design parameters of the sealing lip.
A sophisticated adjustment of seal lip design and contact load allows not only for modification of the average oil metering rate of a valve stem seal, but also for targeted tuning to support lubrication in defined engine application or load conditions.

The Materials and durability performance of the valve stem seal
Our valve stem seals are designed and validated to meet even extended durability targets of the engine. Dedicated FKM rubber material with widely proven performance is being used for standard applications, special material for the most aggressive oils and combustion residues is also available. 

NNK valve stem seal design:
Positive seals : Attach to the valve guide boss. They work like a squeegee, wiping and metering oil on the stem as it passes through the seal.
Deflector seals: Deflect oil away from the valve stem. Also called umbrella seals, they move with the valve stem to shield the valve guide from excess oil.
Stem Seal Materials: Nylon, Teflon, Steel, and Synthetic Rubber (NBR, Polyacrylate, and Viton).

NNK and valve stem seals：
In order to prevent premature hardening and rupture due to insufficient heat resistance of rubber seals, NNK guarantees the service life and ensures that the engine is in a lubricated state. The materials we choose are based on the use environment of the seals and the characteristics of the materials themselves. The oil seals produced have high-quality properties such as high temperature resistance, wear resistance, and long service life. Currently, Viton has excellent heat resistance (up to 450° F) and abrasion resistance and is the material of choice for most valve stem seals. If you need replacement, buy new valve seals，please contact us.
