Extremely small-sized rubber O-rings, miniature rubber sealing gaskets, and washers with precise tolerances. Both the inner bore and outer diameter of the product can be customized with high-precision tolerances. Product identification accuracy is 0.0001mm, and tolerances can be strictly controlled within 0.01mm–0.03mm.

Fluorosilicone star-shaped seals, X-type rubber rings, O-rings made of FVMQ fluorosilicone FLS material. Standard dimensions include American, Japanese, and Chinese national standards. Complete range of O-ring specifications with 8600 mold sizes.Fully automated extruded silicone rubber strips, silicone sealing strips, and round rubber strips (non-foam). Molded with softness starting from 15°, hardness from 20° (lowest for special-shaped strips is 30° hardness, 40°). Perception of softness/hardness varies: above 90–95°, no elasticity; 70–80° for high-pressure sealing; 60–55–50° hardness feels barely squeezable; 45–40–35° hardness can be compressed about 60%. Silicone rubber at 30°, 35°/40° hardness can be compressed 50%–40% by hand. 20° hardness is currently the softest silicone O-ring sealing gasket, feeling very soft and compressible with 90–100% elastic recovery—an excellent material. Dimension series include American standard AS568 seals, Japanese P/G series Xiangjiang seals, Chinese national standard GB O-rings, British BS series O-rings.
