Rubber Gaskets


A rubber gasket is an element that can act as a seal for a range of purposes (this could be for noise reduction, hygiene or liquid sealing). It must be flexible as they are usually compressed between two other surfaces.

Aquaseal Rubber has a comprehensive in-house facility to cut and supply soft-cut, custom hand-cut or die-cut rubber gaskets in any material to suit your needs. We offer press cutting of standard rubber gaskets and also water jet cutting for more demanding requirements.

We manufacture the following rubber gaskets:

  • flange
  • gas
  • water
  • automotive
  • pump
  • food quality
  • steam
  • marine
  • gasket sealants
  • spiral wound

In addition to rubber materials, we manufacture our products in the following materials:

  • non-asbestos (NCAF)
  • treated paper
  • cork
  • paper-backed cork
  • oil tan paper
  • Find out more about our materials on our page: “Rubber We Use

Cutting Rubber Gaskets

Depending on your requirements and desired material, we can use different techniques to create your rubber gasket. Our facilities allow us to manufacture:

  • Soft-cut: This type of gasket is flexible and easily compressed between surfaces, they are easy to install and long-lasting.
  • Hand-cut: For custom orders, gaskets can be hand-cut with high accuracy using precision tools.
  • Die-cut: Dies are metal cutters, shaped to match the desired shape of your gasket. This is an effective process for the efficient production of high quantities.
  • Press cut: Using our travelling swing head press and swing beam press, gaskets can be cut of various sizes and thickness.
  • Water cut: This process uses a waterjet to cut metal parts with high-pressure water.

Which Rubber Gaskets do you need?


Polyurethane gaskets are a good option for products that require good resistance to deformation under load and are able to still perform once exposed to chemicals, oils, and UV light. PU is often used for gaskets that come into contact with vibration due to its tear-resistant properties.

Nitrile (Buna N rubber)

Nitrile gaskets are popular with our oil and automotive clients due to their resistance to petroleum, greases, and oils. Where other rubbers will swell when exposed to these materials, nitrile will remain the same shape. This type of gasket also performs well in high temperatures.

Natural Rubber

Natural rubber is an ideal option for sealing, but they can experience ozone cracking when subjected to too much tension. This type of rubber gasket can perform well in low temperatures.

Neoprene rubber gaskets are most commonly used for external applications as they are a strong material that provides good resistance to abrasion and weathering. Note that this type of material is not suitable for exposure to hydrocarbons and ketones.

Viton Rubber

Viton is the best option for a rubber gasket if the product will be coming into contact with petrochemicals, hydrocarbons, organic solvents, and mineral acids.

Another material often used for an external application is EPDM. These rubber gaskets are impermeable, resistant to abrasion, and perform well when exposed to diluted acids, alkalis, and ketones.

Styrene Butadiene Rubber

Styrene-butadiene rubber gaskets are very long-lasting so suitable and have superior tensile strength. These are suitable for a range of industries and are often viewed as a low-price alternative to natural rubber.

Butyl Rubber

Butyl rubber gaskets are known for their impermeability and therefore commonly used in sealing solutions for gas and compressed air. They are also well-suited to external applications due to their weather-resistant properties.

Fluoroelastomer rubber gaskets have excellent resistance to many acids, chemicals, heat, and oils so they are a great option for a commercial gasket.

Silicone Rubber

Silicone rubber gaskets have superior resistance to extreme temperatures, non-stick abilities, and electrical insulating properties. They are also often used to prevent leaks.
