- 15-20 days
- 2 billion/year
1. First and foremost, rapid prototyping and mold development: Mold development for fluoro rubber O rings only takes 10 days, the earliest prototypes can be produced in 1-2 weeks.
2. Full-range Technical Support: Assistance with 2D/3D drawing conversion. Also, fully customized services including hardness range (20°–90°) and color available.
3. Processing Services: Secondary processing, such as cutting, is offered to fulfill specific installation space requirements.
Despite the small size of FKM O-rings, if they were to fail in environments with high temperatures or chemicals, it could cause a shutdown of the whole equipment, oil leakage or even facilities explosion - in such cases, the repair and time loss would be much more costly than the part itself.
Yida Solutions:
1. Our O-ring FKM is rated for a temperature range of -40°C to 260°C and comes in four grades of fluorine content (A, B, F, and GLT) each designed for specific types of fluids. We do not deal in standard parts but strictly tailor products to your particular chemical media requirements.
2. Low compression set (≤ 20%): Helps reduce the risk of unplanned downtime caused by seal failure.
3. AS9100D (Aerospace) & IATF 16949 (Automotive) certified; 100% physical inspection of every product.

O ring FKM Material Technical Advantages:
We use reverse engineering as a key method in our R&D and manufacturing sealing products. Based on our 1,000+ tested formulas, we are able to replicate the process very accurately to produce the product exactly as per customer specification. We introduce each raw material into the production line through the fully automated barcode system for error prevention and with the dual control operation for the imported materials, we are able to deliver the physical properties with high stability from batch to batch.
We have an in-house mold machining center plus a team with 20 years of experience using Makino machining centers and EDM equipment. These benefits not only help us to keep the mold precision within 0.005 mm but also we can physically assure structural stability with them.
Besides, we have added an AI-driven visual inspection system that creates a triple-layer closed-loop quality control process: thorough material performance testing (CPK/SC/MSA), 2D dimensional examination, and total manual inspection. Through micron-level inspection capabilities, we maintain strict delivery standards for all products from microscopic defects to macroscopic morphology.
Industry Applications:
FKM O-rings find their major application in high-end sectors like automotive, medical, new energy, aerospace, machinery and equipment, industrial automation, and semiconductors. Sophisticated smart manufacturing systems and a well-developed industry supply chain guarantee excellent product quality and performance.

FAQ:
How should O-rings be stored?
① Do not open the original packaging; keep the contents clean and free from damage.
② Avoid direct sunlight and store in a low-humidity environment. Sunlight and moisture accelerate rubber aging and can cause dimensional changes in rubber or plastic materials.
③ If the package has been opened, ensure the contents are free of foreign objects before resealing, and use the original packaging bag.
④ Store away from electrical equipment that generates ozone.
⑤ Do not hang O-rings on nails or wires; doing so can deform the O-ring and damage its edges.
Note: A change in O-ring color or the appearance of white powder (blooming) does not affect the O-ring's performance.
