Our focus areas


Includes both general and bespoke parts which are designed specific to application, with customisable dimensions, material choice and industry certifications.

Gulf offers an extensive range of standard industry size O-Rings, in a wide range of polymer materials, ranging from EPDM, NBR, Viton FKM, Silicone and many more.


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.
