Why Use Nylon Washers for Automotive Applications?

The automotive industry involves the manufacturing of motor vehicles and their components, such as engines, tires, batteries, and vehicle bodies. Passenger vehicles, light trucks, and commercial vehicles are all types of automotive products that require washers in their assembly.


The use of plastic washers in particular has many benefits for automotive applications. Plastic washers are incredibly versatile and durable. They have many advantages that enable them to be an important aspect of vehicle manufacturing. In this blog, we’ll discuss the advantages of nylon washers for the automotive industry.

Why Are Nylon Washers Used In Automotive Manufacturing?

Nylon washers are frequently chosen by the automotive industry due to their long-lasting strength. They perform well in high-temperature environments. This makes them particularly well suited for automotive applications, where they could be exposed to engine heat or harsh environmental conditions. Nylon washers are also chemical-resistant, which is a significant benefit to the automotive industry, where washers come into contact with many oil or petroleum-based chemicals and other fluids. These conditions would cause corrosion in certain materials, such as metals. Nylon, however, is resistant to corrosion and delivers strength and reliability for much longer than a metallic washer could.

Nylon washers stand up well against pressure and wear, and the material itself is highly workable, which allows for flexibility in design. Nylon is a cost-effective choice, and its lightweight nature can contribute to the vehicle’s fuel efficiency. Nylon washers can be molded, extruded, and stamped into different configurations, making them ideal for auto part manufacturing. Nylon’s benefits such as corrosion and temperature resistance, as well as its lightweight nature, all help to increase the life span of the vehicles they are used in.

What Are Common Automotive Applications for Nylon Washers?

There are several applications for nylon washers within the automotive industry. For example, since they can withstand extreme temperatures and petroleum-based chemicals, they are often found in vehicles’ engine compartments. They are also used to prevent leakage by holding automotive bolts in place, and secure radiators, and distribute pressure. Some additional applications include:

  • Engine compartments stator, armature, and rotor componentsautomotive nylon washers
  • Gasoline motors
  • Exhaust systems
  • Fenders
  • Airbag systems
  • Brake systems

There are several types of nylon plastic, each with different qualities and benefits. All types are known for their strength; however, nylon 6/6 is particularly strong and resistant to extreme temperatures, making it well suited to many automotive component applications.

Why Choose Nylon Over Metallic?

There are several advantages that nylon washers have over metallic washers when used in automotive applications. First, the low surface friction of nylon makes it more long lasting than metallic washers and less likely to deteriorate as quickly. Metal washers suffer from many problems with deterioration and rust due to the friction they experience. Additionally, nylon is much better at absorbing shock and noise than metal, which creates a significantly quieter user experience. Nylon is a very lightweight material, and it is inexpensive to produce, which offers savings for both the customer and manufacturer.

Nylon vs. Teflon Washers

Most washers can be made of either nylon or Teflon. These versatile polymers offer greater mechanical strength and higher resistance to friction than traditional materials such as aluminum, steel, and bronze, making them a more durable and cost-effective solution in most industrial applications.

Despite their similarities, however, nylon and Teflon each have distinct properties that make them better suited to particular functions. Teflon, for example, is a hydrophobic material, while nylon is hydrophilic. As a result, any piece of machinery that requires greater lubrication should be constructed with Teflon rather than nylon, since Teflon’s water-repellant properties make it a stronger lubricant.

Nylon and Teflon each offer an array of benefits, but any manufacturer should take the time to carefully consider their needs before investing in washers made from either material. To help you make an informed decision, we took an opportunity to compare and contrast these common building materials below.

The Properties of Nylon and Teflon

Nylon and Teflon are both synthetic polymers used in a variety of industrial applications. Nylon is a thermoplastic made when an amide reacts with dicarboxylic acid, while Teflon is created by polymerizing tetrafluoroethylene.

Because they’re the products of different processes, nylon and Teflon each have unique physical and chemical characteristics. The chart below provides an overview of the essential similarities and differences between them:



·         Consists of carbon, hydrogen, oxygen, and nitrogen

·         High molecular weight

·         High mechanical strength

·         Has lower melting point

·         Offers increased resistance to friction

·         Conducts electricity well

·         More chemically reactive

·         Thermoplastic

·         Hydrophilic

·         Consists of carbon and fluorine

·         High molecular weight

·         High mechanical strength

·         Has high melting point

·         Offers increased resistance to friction

·         Does not conduct electricity well

·         Less chemically reactive

·         Thermoplastic

·         Hydrophobic

What You Should Consider

As you can see, while nylon and Teflon share many properties, the slight differences between them are equally significant. Manufacturer must thoroughly evaluate their specific needs before committing to washers made with either material.

Nylon washers can be found in a wide range of applications, including aerospace manufacturing, defense contracting, the automotive industry, construction, and plumbing. In all of these fields, they’re most widely used in moving components like gears and bearings. Because of their heightened resistance to heat, friction, and corrosion, they are an excellent choice for the complex machinery involved in most heavy duty applications.

Teflon washers can provide many of the same benefits, but they perform better in certain environments than their nylon counterparts. Because Teflon has a higher melting point, for example, it can better withstand the heat generated by electrical equipment, making it a better choice for applications that require extreme temperatures.

Similarly, Teflon’s hydrophobic properties may be useful in any applications that expose components to moisture. While nylon provides some protection against corrosion, it does absorb any moisture that comes into contact with it, which can leave parts less lubricated than they should be.

In short, nylon and Teflon can handle most of the same applications with extreme efficiency and durability. If you rely on particularly sensitive equipment, however, Teflon can better protect it from environmental damage.
