Disposable Syringe Rubber Stopper

As a source factory with 18 years of production experience in medical syringe accessories, our factory produces Disposable Syringe Rubber Stopper, which is the core sealing accessory of all kinds of disposable syringes. This rubber stopper directly determines the sealing performance, injection feel and liquid medicine safety of the syringe. We adopt medical-grade rubber formula and high-precision vulcanization technology, which can perfectly match the syringe barrels of mainstream specifications on the market. It not only ensures smooth injection without jamming, but also completely eliminates side leakage and liquid leakage problems. Disposable Syringe Rubber Stopper has good liquid medicine compatibility, can adapt to most conventional injection agents, will not react with liquid medicine to affect the efficacy, and is a core supporting product for syringe manufacturers and medical consumable channel distributors.

Our Disposable Syringe Rubber Stopper takes medical-grade butyl rubber as the main raw material, with pure formula and no impurities, good biocompatibility, no hemolysis and no sensitization. The product is molded by precision compression, with dimensional tolerance controlled within ±0.03mm. The fit with the inner wall of the syringe barrel has been verified by tens of thousands of injection tests, with reliable sealing and very low residual liquid volume. The surface of the rubber stopper is treated with special lubrication, with uniform injection resistance, and no adhesion will occur after long-term storage. All products are produced and packaged in clean workshops, and have undergone strict impurity testing and aging testing to ensure stable performance during the storage period. With accurate dimensions and reliable sealing performance, Disposable Syringe Rubber Stopper has become a fixed supporting supplier for many domestic syringe manufacturers, and is also exported in batches to overseas markets.
