Rubber Gaskets

Whilst rubber gaskets may seem relatively insignificant components for those without the necessary industry knowledge, they are actually extremely important in many aspects of modern life. They’re present in anything from refrigerators to road bridges and complex machinery.

As a leading supplier of rubber gasket in Australia, we’re familiar with the challenges that manufacturing brings and are fully able to meet them. Gaskets provide a mechanical seal to prevent leaks of liquids or gases, as a barrier between two objects or as protection from outside elements. Their role is absolutely critical because a failure can pose serious problems, so our manufacturing process is all about paying attention to detail and enforcing strict quality control measures.

Rubber Gasket — a Vital Component in Many Products

The versatility of rubber gasket seals means they’re used in countless products that all vary in characteristics and needs. As a result, almost every gasket is custom-made to suit a particular application precisely. Consequently, you need rubber gasket manufacturers such as Gulf Rubber to ensure your gaskets satisfy your needs and meet exacting specifications.

A Wide Range of Materials and Suitability

For each new gasket, we’ll take the technical specification of your product to determine what is needed, particularly in terms of rubber gasket materials. These rubber compound materials have varying properties, especially relating to their:

  • Durometer, which is a measure of a material’s hardness and its resistance to permanent indentation. Materials with a lower durometer are more supple but are prone to indentations while those with a higher durometer are heavier with more density and less flexibility.
  • Tensile strength, which determines the maximum stress a material can undergo when stretched before it tears or cracks.

Various materials have different uses due to their varying durometer and tensile strength, and include:

  • Nitrile. A commonly used material that is resistant to oil and grease, has superior tear and abrasion resistance but does not weather well. It is often used in automotive applications and food processing.
  • Neoprene. This all-purpose polymer has good resistance to weathering and ozone, and moderate resistance to petroleum products. Gaskets made from this material are easily compressed and resistant to temperature extremes, so are often used for refrigerator doors.
  • EPDM can withstand extreme temperature ranges and has excellent resistance to ultraviolet rays, weathering, oil and grease, making it ideal for outdoor applications.
  • Silicone is resistant to ozone and ultraviolet light, is suitable for high-temperature conditions and can withstand high pressure but has poor tear strength. It is commonly used in the automotive industry and for electrical insulation.

Helping you Create the Ideal Gaskets

Using the correct material is crucial to the success of any industrial gaskets and our broad industry experience in rubber engineering means we are able to get it right every time. We also use a variety of cutting methods — hand cutting, die cutting, water jet cutting — as well as creating gaskets from moulds, so will use the most appropriate one for every job.

Custom Design Capability

Every gasket we produce is bespoke and so will meet the specification of every job exactly. You know what you want, and we know how to provide it, so get in touch and we’ll quickly and efficiently produce the gaskets you need. We pride ourselves on high-quality manufacturing, exhaustive quality control, excellent customer service and fast delivery of exactly the right components so we won’t delay your operation.

Quality Assurance

Gulf’s team of engineers ensure all factories around the world meet quality standards required for ISO 9001 certifications. All products go through rigorous analysis and testing on a range of metrics, including tensile and tear strength, stress relaxation, and compound rheology. Our stringent process controls use tools such as Poka-Yoke / Error-Proofing, Statistical Process Control (SPC), Process Failure Mode Effects Analysis (PFMEA) and automated inspection tools.

Other analytical tools include Design of Experiments (DoE), Finite Element Analysis (FEA), Failure Modes and Effects Analysis (FMEA), Gauge R&R and 8D Problem Solving.

Custom Design Capability

Using DFMA (design for manufacture and assembly), we can help duplicate parts, improve existing parts, or develop new ones. In partnership with you, products are developed, tested, and delivered to streamline production and simplify your supply chain, often resulting in lower cost products and quicker delivery time.
