4.Our O-Rings: Burr-Free, Smooth Surface, Precision Molded
Our O-Rings are manufactured with high-precision molds and strict deburring processes to ensure:
•Completely smooth surface for better sealing contact
•Consistent dimensions & tight tolerances
•Lower compression set for longer service life
•Even friction during operation to reduce wear and leakage
A clean, smooth surface means more reliable and durable sealing performance.
5.Avaliable surface treatments：
To enhance performance and extend service life, our O-Rings are available with multiple advanced surface treatment options:
• Teflon (PTFE) Surface Coating
A thin PTFE coating that significantly reduces friction, improves chemical resistance, and enhances installation ease. Ideal for applications requiring smooth movement or exposure to aggressive chemicals.
• Lubricant Spray Coating
A uniform lubricant finish that improves assembly efficiency, prevents sticking, and reduces startup wear. Commonly used in dynamic sealing systems, hydraulic components, and precision assemblies.
• Teflon (PTFE) Encapsulation
A solid PTFE outer jacket combined with an elastomer core. This structure provides exceptional chemical resistance, wide temperature capability, and superior durability-perfect for extreme or corrosive environments.
