Proven Global Track Record
We have been successfully exporting goods to Europe, the Middle East, South America and Africa, and we consistently receive satisfied feedback from our clients who value our good quality and reliable performance.
O-rings are mechanical seals used to prevent the leakage of liquids or gases between mating surfaces. Typically donut-shaped and made from elastic materials like rubber, they work by filling the gap between joining parts. When compressed, they create an impenetrable barrier that scales in tightness with pressure.
From standard elastic sealing to ultimate chemical defense, our O-ring product portfolio delivers outstanding physical and chemical performance integrated across four key dimensions:
Extreme Temperature Resilience
We offer superior adaptability over extreme temperature ranges. High flexibility silicone materials possess superior rebound property in low temperature environment, and the FFKM & Fluororubber materials are capable of being exposed in high temperature baking continuously with no soften or harden condition, low compression set.
01
Top-Tier Chemical & Media Resistance
Our FFKM O-rings or PFA coated O-rings are like a "chemical shield," they don't swell or disintegrate when exposed to aggressive acids, strong alkalis, corrosive solvents, petroleum products or oils and fuels (as used in the automotive and aircraft industries) because of their high chemical inertness.
02
Innovative Dual-Benefit Engineering
Our composite series, including the PFA Coated Ring, combines the seamless flexibility of a rubber core with the best in chemical resistance offered by the fluoropolymer jacket. The friction level is also very low, which helps make the material self-lubricating to minimize wear in a dynamic application.
03
Stringent Hygiene & Safety Compliance
Material lines (such as high-purity silicone) are non-toxic, odorless and highly biocompatible. With advanced high-precision molding, the O-rings have flash lines so small that they can fully satisfy the strict zero-contamination requirements in medical, food-grade, and semiconductor cleanroom applications.
04
Premium Materials & Compliance
All raw materials we use are obtained from globally leading suppliers who meet worldwide certification standards, including FDA, RoHS and REACH.
Ultra-Tight Tolerances
We can use injection and compression molding techniques as well as high-grade tooling to reduce the size of parting lines and to deliver tolerance that is much tighter than most international standards allow.
Comprehensive Catalog & Customization
We keep a wide variety of stock sizes (AS568, JIS, GB) with quick turn-around on custom tooling for custom sizes, non-standard cross sections and special durometers.
Low Total Cost of Ownership (TCO)
Exceptional resistance to compression set means longer life, which means drastically reducing unexpected downtime and costly seal failure overheads.
Proper storage and handling are crucial to maximizing the shelf life and ensuring the optimal on-machine performance of your O-rings:
Preventing Physical Damage
Do Not Hang: Never hang O-rings on hooks, nails, or wires, as localized hanging stress can cause permanent deformation or micro-tears.
Avoid Compression: Do not store heavy items on top of the O-rings or stack them too high, preventing permanent plastic deformation.
Installation & Handling Care
Inspect the Hardware: Before installation, ensure that all grooves and shafts are smooth and free of burrs or sharp edges to prevent scratching the O-ring surface.
Lubrication Assistance: Apply an adequate amount of compatible lubricant (such as silicone grease) during assembly to reduce friction. Never use low-quality oils that may cause rubber swelling or degradation.
