Durable Automobile Oil Seals to Support Rough Automotive System Applications - FITCO

Durable Automobile Oil Seals to Support Rough Automotive System Applications

Automotive seals play critical roles in different types of four wheeler vehicles. They are primarily used with bearings, hubs, and different types of mechanical systems. The seals are designed to prevent leakage of oil, lubricant, and component damage due to heat. FITCO provides a wide range of sealing solutions to meet the various needs of automotive manufacturing. Our seals can be installed in systems of commercial cars, buses, trucks, and motorcycles.

At FITCO , we provide oil and shaft seals as solutions for automobiles. They are designed to provide stability and reliability in terms of performance and service life. They are ideal for any kind of fluid power or handling equipment.

The shaft and oil seals provides benefits of decreased friction, easy fit, and mechanical protection. The seals also reduce demands on the automobile system in terms of tolerance, hardness, and smoothness.

The following points showcase the types of seals that we provide, as well as the different material options available.

• Oil Seals: Oil seals are designed as automotive radial lip seals. These seals create a leak proof layer between the sealing lip and the shaft. We utilize a non-molybdenum based grease to lubricate the seal. This grease is popular as it is used with all industrial seals, and can disperse in engine oil. We can design these oil seals in different materials, such as polyurethane, PTFE, silicone, nitrile, and ultra high molecular weight polyethylene.
• Industrial Gamma Seals: These seals comprise a two part construction, one is a metal case, and an elastomer sealing member. The protective case ensures that the seal can operate in extremely rough environments. The seal provides protection against liquid spatters, and external contaminants like dust and dirt. The gamma seals can be used as both a clearance seal, and deflector ring.

FITCO automotive sealing products can be installed and used with a wide variety of automobile systems, including:

• Crankshaft seal
• PTFE shaft seals
• Valve stem seals
• Universal joint seal
• Power steering seals
• Elastomeric shaft seals
• Low friction engine seals

Oil Seals - FITCO

Oil Seals also known as Rotary shaft seals play a key role in extending the operating life of bearing systems and reducing the overall costs of maintaining these systems. The primary function of a rotary shaft seal is to retain bearing system lubricants therefore allowing the bearings to operate in optimal levels of lubrication. The secondary function of a rotary shaft seal is to exclude contaminants from the system, contaminants that can both damage bearings and break down the effectiveness of lubricants. 

Oil Seals are manufactured  from shafts ranging 1/4” to 40”. The design guide offers assistance in selecting the appropriate style and material of seal for your particular operating environment. If heat or chemical attack are a concern we offer Viton®, and other material Silicones and Nitriles rubbers. Additionally, design parameters for shaft and bore configurations are provided.

A complete selection of Inch & Metric sizes of  Rotary shaft seals.  Available in a range of compounds and a wide selection of oil seal lip styles.

PTFE O-Rings and Seals - FITCO

PTFE O-Rings and Seals are often used in hydraulic and pneumatic applications and offer several advantages over traditional elastomer solutions. Delivering low friction at high pressure is arguably the most important of these however; low stick slip, high abrasion resistance and universal chemical compatibility are all factors which make it an important option when designing efficient and reliable sealing systems.


Seals in PTFE are typically energized by a static secondary system.  In most cases, this will be in the form of an elastomer which is compressed radially to provide a static seal and the force necessary for the profile ring to seal at low pressure.   In other cases, metallic springs can be used where there is a media compatibility issue for example.  PTFE materials vary depending on the particular application involved.  Resistance to extrusion, abrasion resistance and sealing efficiency can all be affected by the individual compound and geometry being used.

The sealing efficiency of  PTFE material is generally worse than that of traditional elastomer solutions. Therefore, careful consideration of the overall seal specification is required for the system to operate successfully. This often results in combinations of seals being used, including those manufactured from elastomer materials. With this approach, seal systems can be designed to have low friction characteristics and 100% sealing efficiency.

FKM Fluoroelastomer / Viton O-Rings and Seals

O-Ring and Seals protection for harsh environments remains a continuing challenge in many industries. One of the best solutions for long-term efficiency and reliability is the use of fluorocarbon elastomers (FKMs).

In general, most fluorocarbon elastomers (FKMs) resist temperatures up to 204°C/400°F and remain flexible at lows of -26°C/-15°F.  Superior compression set and recovery, and high performance in contact with severe chemicals, are the hallmarks of fluoroelastomers.  They perform well in vacuum applications and have very good ozone , weather and aging resistance.  In addition, the durability of fluoroelastomer seals saves on downtime and replacement costs.

FKM O-Rings and Seals are frequently used in industrial, oil and gas, automotive, aerospace and defense, and medical and life sciences, among other industries, to seal against gasoline, butane, propane, natural gas, grease, hydraulic fluids, solvents, and mineral-based oils and acids.
Ideal for sealing in critical harsh environments, fluorocarbon elastomers are available in a wide selection of stock and custom formulations, with differences in fluid resistance based on the amount of fluorine added.  Some examples of these varieties of FKMs:

• An economical FKM with typical chemical resistance and temperature range is available with a 75 durometer, tensile strength of 1000, 200% elongations at break, 100ppi tear strength, and compression set of 36%
• Another 75-durometer FKM designed for high temperature, offers excellent resistance to acids, bases, sour gas and oil, high pressure steam and alcohols, and high pH corrosion inhibitors, as well as satisfactorily resisting ketones, esters and ethers, aromatic solvents and fuels.  Tensile strength of this formulation increases to 2600 and tear strength of 128ppi, with a slight drop in compression set of 31%.  While most fluorocarbon elastomers do not perform well in steam or hot water environments, a select group of custom compounds such as this are specifically designed for them
• On the other hand, a low compression set FKM compound (7%) that is superior in resisting aliphatic and aromatic hydrocarbons, animal and vegetable oils, chlorinated solvents, fuels, lubricants, ozone, petroleum oils, and weathering, is not recommended for use with acids, hot water or steam, esters, ethers, ketones, and certain amines
• A premium-grade FKM seal that is heat-resistant to 500°F but has a lower compression set of 16% meets Mil-R-25897, ASTM D-2000, and AMS-7278D requirements

 Designing an FKM O-Rings and  Seals for the best combination of attributes for any demanding environment must include precise specifications for:

• Temperature
• Chemical Resistance
• Mechanical Stresses
• Compression Load
• Aging
• Ozone and Weathering
• Flame Retardance
• Gas Permeability
• Fungus and Mold Resistance
• Electrical Considerations
• Other Environmental Conditions
• Installation Considerations

While FKM fluorocarbon elastomers is a more expensive option, their use may actually save significantly on downtime and replacements, offering a savings of labor, parts and productivity costs over the life of the product.
