Cutting Industries are a leading manufacturer of custom nitrile washers for OEM manufacturers, maintenance teams and industrial applications throughout the UK and Ireland.

Nitrile rubber, also known as NBR, is one of the most widely used sealing materials where resistance to oils, fuels and grease is required.

Using CNC cutting and die cutting technology, we manufacture nitrile washers to your drawing, sample or specification in both prototype and production quantities.

Whether you require a small development batch or high volume production runs, we can supply precision cut nitrile washers with fast turnaround times.

What Are Nitrile Washers?

Nitrile washers are sealing components manufactured from NBR rubber.

The material is specifically designed to perform in environments where oils, fuels, hydraulic fluids and lubricants are present.

Compared to general purpose rubber materials, nitrile offers significantly better resistance to petroleum based products while maintaining good compression and sealing performance.

Nitrile washers are commonly used in:

• Fuel systems
• Hydraulic equipment
• Pumps
• Valves
• Automotive components
• Agricultural machinery
• Industrial processing equipment
• Fluid transfer systems

Nitrile Washer Material Properties

Why Choose Nitrile Washers?

Nitrile remains one of the most popular sealing materials because it combines excellent oil resistance with cost effective manufacturing.

Benefits include:

• Excellent resistance to oils and fuels
• Good compression set characteristics
• Strong mechanical properties
• Reliable sealing performance
• Wide hardness range available
• Suitable for industrial environments
• Cost effective compared to premium materials

For applications involving aggressive chemicals or extreme temperatures, our Viton washer solutions may provide a better option.

Available Nitrile Grades

Nitrile washers can be manufactured in a range of material grades and hardness levels to suit different sealing applications.

Common options include:

• 40 Shore A for softer sealing applications
• 60 Shore A for increased flexibility
• 70 Shore A as the most common industrial grade
• 80 Shore A for improved durability
• 90 Shore A for high load applications

Material selection depends on operating pressure, compression requirements, chemical exposure and service conditions.

Components can be supplied from customer drawings, CAD files or physical samples.

Can Nitrile Washers Be Self Adhesive?

Yes. Nitrile washers can be supplied with pressure sensitive adhesive backing to simplify installation and assembly.

Self adhesive nitrile washers are commonly used where accurate positioning is required before final assembly.

For more information, see our guides on self adhesive gaskets and kiss cutting.

Industries and Applications

Nitrile washers are used across a wide range of industries where reliable sealing performance and resistance to oils, fuels and lubricants are required.

We manufacture custom nitrile washers for OEM manufacturers, engineering companies, fuel handling businesses and maintenance teams throughout the UK and Ireland.

Automotive

Nitrile washers are widely used in automotive systems where exposure to oils, lubricants and fuels is common.

Applications include:

• Fuel system sealing
• Engine components
• Hydraulic systems
• Fluid reservoirs
• Maintenance and repair parts

Industrial Manufacturing

Many industrial systems rely on nitrile washers to provide dependable sealing performance in equipment exposed to oils and hydraulic fluids.

Applications include:

• Pumps
• Compressors
• Valves
• Process equipment
• Fluid handling systems

Agriculture

Agricultural machinery regularly operates in harsh environments where resistance to oils and fuels is essential.

Common applications include:

• Hydraulic systems
• Fuel systems
• Machinery maintenance
• Replacement sealing components

Nitrile Washers for Fluid Handling Equipment

Nitrile rubber is one of the most widely used sealing materials throughout the fuel industry due to its excellent resistance to petrol, diesel, lubricants and petroleum based products.

Typical applications include:

• Fuel tanker equipment
• Fuel transfer systems
• Fuel pumps
• Storage tanks
• Dispensing equipment
• Pipe flange sealing
• Tank inspection covers

For many fuel handling applications, nitrile provides an excellent balance between sealing performance, durability and cost.

If your application involves more aggressive chemicals or elevated temperatures, our Custom Viton Washers may be more suitable.

Nitrile vs EPDM Washers

Choosing the correct washer material is critical for long term sealing performance.

Nitrile is typically selected where oils, fuels and lubricants are present.

EPDM is generally preferred for:

• Water systems
• Outdoor environments
• UV exposure
• Weather resistant applications

If your application involves petroleum based products, nitrile is usually the preferred material.

For a detailed comparison, read our guide: EPDM vs Nitrile Gasket Guide

Nitrile vs Other Washer Materials

For applications involving oils and fuels, nitrile is often the most cost effective option. Where extreme temperatures or aggressive chemicals are present, silicone or Viton may be more suitable.

CNC Cut Nitrile Washers

Our CNC cutting equipment allows us to manufacture nitrile washers with excellent dimensional accuracy and repeatability.

Benefits include:

• Fast prototyping
• Consistent production quality
• Minimal tooling costs for low volume orders
• Efficient manufacture of complex washer profiles
• Rapid design revisions

For larger production quantities, die cutting may provide the most economical manufacturing solution.

Typical Tolerances

Using CNC knife cutting and die cutting technology, Cutting Industries can typically achieve tolerances of approximately ±0.5mm, with tighter tolerances possible depending on material type, thickness and component geometry.

Our team can advise on achievable tolerances during the quotation process.
