Selecting the correct washer material is critical in modern engineering and industrial manufacturing. Across industries such as automotive, aerospace, electronics, chemical processing and construction, washers play an essential role in load distribution, sealing performance, vibration reduction and operational reliability.
Two of the most widely used washer materials are stainless steel and PTFE (Polytetrafluoroethylene).
At Stephens Gaskets, we manufacture and supply precision stainless steel and PTFE washers in the UK, helping businesses choose the most effective solution for their exact operational requirements. Both materials offer distinct advantages depending on the application, environmental conditions and performance demands.
As engineering systems become increasingly advanced in 2026, selecting the correct washer material has become more important than ever for improving machinery efficiency, reducing maintenance costs and ensuring long-term reliability.
What Are Stainless Steel Washers?
Stainless steel washers are precision-engineered metal components designed to:
- Distribute loads evenly.
- Protect surfaces from damage.
- Reduce wear and movement.
- Improve fastening reliability.
- Resist corrosion and environmental exposure.
They are widely used in applications requiring high mechanical strength and long-term durability.
According to the original Stephens Gaskets article, stainless steel washers are renowned for their exceptional durability, high tensile strength and corrosion resistance.
This makes them one of the most trusted washer materials across demanding industrial environments.
What Are PTFE Washers?
PTFE washers are manufactured using Polytetrafluoroethylene, a high-performance fluoropolymer known for its:
- Chemical resistance.
- Low friction properties.
- Temperature tolerance.
- Electrical insulation capabilities.
PTFE washers are commonly used in environments where corrosion, chemical exposure or electrical insulation are major considerations.
The original article highlights PTFE’s excellent resistance to chemicals, acids and solvents, making it ideal for aggressive industrial environments.
Stainless Steel vs PTFE Washers: Key Differences
Although both materials are widely used across engineering industries, they perform very differently depending on the operational environment.
Strength and Mechanical Performance
1. Stainless Steel Washers
Stainless steel washers provide:
- Exceptional tensile strength.
- High load-bearing capability.
- Excellent structural stability.
- Long-term durability under pressure.
They are ideal for:
- Heavy-duty industrial machinery.
- Automotive systems.
- Structural engineering applications.
- High-stress mechanical assemblies.
Because stainless steel is highly durable, it performs exceptionally well in environments involving significant mechanical stress.
2. PTFE Washers
PTFE washers are softer and more flexible than metal alternatives.
Their benefits include:
- Reduced friction between components.
- Non-stick performance.
- Chemical resistance.
- Lightweight operation.
However, PTFE can deform under high pressure and may experience creep over time under continuous load.
This means PTFE washers are generally better suited to specialised sealing, insulation and low-friction applications rather than high-load structural systems.
Corrosion and Chemical Resistance
1. Stainless Steel Washers
One of stainless steel’s biggest advantages is its resistance to corrosion.
This makes stainless steel washers ideal for:
- Outdoor environments.
- Marine applications.
- Industrial processing systems.
- Moisture-exposed machinery.
Stainless steel maintains structural integrity even in harsh environmental conditions.
2. PTFE Washers
PTFE offers superior resistance to:
- Aggressive chemicals.
- Acids.
- Solvents.
- Corrosive industrial fluids.
PTFE is often the preferred solution in:
- Chemical processing plants.
- Pharmaceutical manufacturing.
- Food production systems.
- Laboratory equipment.
In highly corrosive environments, PTFE can outperform many metal alternatives.
Temperature Resistance
1. Stainless Steel Washers
Stainless steel washers maintain their structural integrity across both high and low temperatures.
This makes them suitable for:
- Aerospace systems.
- Automotive engines.
- High-temperature industrial machinery.
Their ability to resist thermal expansion and mechanical deformation makes them highly reliable in demanding environments.
2. PTFE Washers
PTFE washers offer exceptional thermal resistance and can withstand temperatures ranging from approximately:
-200°C to +260°C
This makes PTFE ideal for:
- Cryogenic systems.
- High-temperature sealing applications.
- Specialist industrial equipment.
Its temperature stability is one of the reasons PTFE is widely used in advanced engineering industries.
Electrical Properties
1. Stainless Steel Washers
Stainless steel conducts electricity, although not as efficiently as some other metals.
This can be beneficial or problematic depending on the application.
2. PTFE Washers
PTFE is an excellent electrical insulator.
This makes PTFE washers highly suitable for:
- Electronic systems.
- Electrical enclosures.
- Insulated assemblies.
- High-voltage environments.
In electrical applications where preventing conductivity is essential, PTFE is often the preferred solution.
Weight Considerations
1. Stainless Steel Washers
Stainless steel washers are heavier than polymer alternatives.
While this contributes to strength and durability, it may be a disadvantage in:
- Aerospace applications.
- Lightweight engineering systems.
- Weight-sensitive assemblies.
The original article notes that weight can be a limiting factor for some projects.
2. PTFE Washers
PTFE washers are lightweight and easy to integrate into:
- Compact assemblies.
- Lightweight equipment.
- Specialist technical systems.
This makes PTFE attractive for industries prioritising weight reduction and flexibility.
Common Applications for Stainless Steel Washers
According to the original Stephens Gaskets article, stainless steel washers are widely used in:
- Automotive engineering.
- Aerospace systems.
- Marine applications.
- Construction projects.
These industries require strong, corrosion-resistant and durable fastening solutions.
Common Applications for PTFE Washers
PTFE washers are commonly used within:
- Chemical processing systems.
- Food and beverage equipment.
- Electronics manufacturing.
- Medical devices.
Their resistance to chemicals, temperature extremes and electrical conductivity makes them ideal for specialist applications.
How To Choose Between Stainless Steel and PTFE Washers
The correct material depends entirely on the operational environment and performance requirements.
1. Choose stainless steel washers if you need:
- High strength.
- Structural durability.
- Corrosion resistance.
- Heavy load performance.
2. Choose PTFE washers if you need:
