Leading Rubber O Ring Supplier – Gulf Rubber Australia

Gulf Rubber Australia GRA are amongst Australia’s leading rubber and plastics manufacturing company. No other company is better placed to solve your current large O Ring supply issue. Depending on your product development journey, you could be looking for a specification that already sits in our stock portfolio. Great news if it is. If not, then we can custom engineer a bespoke solution as we specialise in concept to delivery project management of specialist component parts. If you need something that doesn’t exist, we can create it for you, cost-effectively and to the highest quality.

What Makes the GRA Premier Rubber O Ring Suppliers?

There are five areas of manufacturing excellence that make GRA a stand-out sealing ring manufacturer.

  • Proven past performance – GRA works to low tolerances and guaranteed material properties. This can only be achieved through accurate design, precise manufacturing and strong product analysis.
  • Robust testing – all supply of seal O rings are tested for long-term performance. This process includes stress relaxation, heat ageing and chloramine resistance testing.
  • Large range of materials – O rings can be manufactured from a vast range of materials and even customised to meet any specific product application.
  • Zero defect assurances – all manufacturing is subject to automated inspection to guarantee a zero-defect status, essential for all critical applications.
  • International standards – all GRA manufactured rubber rings meet a vast range, including all the major international standards and follow a set of manufacturing processes that are ISO 9000 and QS 9000 certified.

Unrivalled Service Approach from Industry Respected O Ring Manufacturer

Most of our new clients come to us by way of personal introductions and recommendations. Technical Directors looking for specific results, tend to trust industry acquaintances for quality introductions. This is particularly true for several of our clients who searched for rubber O ring manufacturers for all purposes including automotive rubber manufacturing.

The process of being considered to supply or manufacture custom o rings for a client follows the same first step. A meeting to determine the needs and ambitions of the client. We find this is best approached at a technical level so that the component specification takes centre stage, followed by the customer support mechanisms we put into our project management planning.

By the end of the first consultation, we’ve usually found all the required common ground to make the rubber o rings wholesale supply and /or manufacturing a real prospect. We believe the best results come through close consultation and timely project management.

We have a customer service focus which has won the company impressive blue-chip contracts with global giants such as Daimler Benz, Dupont and BMW.

Our focus areas


From silicone diaphragms with exceptionally tight tolerances used in agricultural water drippers, to fabric reinforced rubbers and parts with dynamic function, Gulf draws on extensive experience and capabilities to provide superior part performance.

Custom Parts

Development, production and supply of rubber parts that are specific to the application of original equipment manufacturers. These parts typically have unique dimensions, tight tolerances, specific material properties and industry required certifications.

Integrated Components

Gulf manufactures integrated components, supplying complete sub-assemblies to streamline your production and simplify procurement. Inter-material bonding (of rubber, plastic, metal and fabric) and overmoulding provide for improved performance, a reduced number of components and reduced assembly

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 Capabilities

Custom Design Capability

At Gulf, we thrive on the opportunity to innovate. If you need a custom product or solution, then our trusted engineers, chemists, and technologists will work tirelessly to deliver above and beyond your expectations. Whatever your specifications or requirements, you can rest easy knowing that you’ve got the strategic partner who can solve the problem.

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.
