As Tunç Automotive, we manufacture premium-quality Polyurethane (PU) O-rings and sealing components for hydraulic, pneumatic, and industrial systems operating under severe mechanical stress. In aggressive working environments involving extreme wear, high pressure, tearing, and constant oil contact—where standard rubber materials (such as NBR, Silicone, etc.) fall short—we deliver the superior material life of polyurethane to the service of the industry.

​

 High Production Capacity of 20,000 Units Daily: Utilizing our advanced polyurethane processing equipment and optimized mold designs, we carry out high-volume, standardized mass production of 20,000 units per day. We fulfill the component procurement of your large-scale projects with Just-In-Time (JIT) delivery.

​

 Superior Mechanical Properties and Resistance: Thanks to their flexible structures that can be optimized within hardness ranges of 70 to 90 Shore A, our polyurethane O-ring components exhibit excellent resistance to abrasion, tearing, and tensile failure. They offer maximum sealing performance against mineral oils, greases, ozone, and hydraulic fluids.

​

 Custom Size Manufacturing via Toolroom Integration: In addition to standard dimensions, we engineer O-ring designs with custom cross-sections and diameters tailored to your specific sealing grooves in our own precision toolroom. Leveraging our rapid mold deployment capabilities, we produce custom contract manufacturing and OEM solutions for your projects.

​

 We stand by you with our robust production line for your high-volume Polyurethane O-ring requirements, custom sealing projects, and contract manufacturing demands. You can contact us for sample requests, technical details, and price quotations.
