Medical Rubber Gasket Seal

With 18 years of R&D and production experience in medical seals, our factory has developed the Medical Rubber Gasket Seal, a specialized face-sealing rubber component designed for end-face and flange sealing scenarios in medical equipment. Different from conventional line-sealing O-rings, this gasket features a full-plane contact structure with a larger contact area and higher pressure-bearing capacity. It forms a uniform and stable sealing layer on equipment flanges, pump end faces and pipeline connections, effectively preventing liquid and gas leakage under high pressure. The Medical Rubber Gasket Seal is widely compatible with various static sealing scenarios in medical equipment, serving as an essential basic sealing element in medical device systems and pipeline networks.

Our Medical Rubber Gasket Seal is made of medical-grade high-performance synthetic rubber with a pure formula free of harmful leachables, and its biocompatibility meets medical standards. The product is manufactured through precision compression molding and secondary vulcanization, with flatness controlled within 0.02mm. Its surface is smooth without flash or bubbles, fits tightly against the sealing end face, and delivers zero leakage under pressure. The product exhibits excellent compression set resistance, maintaining its elasticity without degradation after long-term fastening, with a sealing service life of over 5 years. Every Medical Rubber Gasket Seal undergoes strict sealing and aging resistance tests to ensure stable performance throughout the equipment's entire lifecycle. With reliable quality and complete specifications, this product has been supplied to numerous medical device manufacturers at home and abroad, securing steady bulk orders.

To meet the plane sealing requirements of the Medical Rubber Gasket Seal, we have established a full-process quality control system. Full material inspection is conducted upon raw material receipt to verify key performance indicators such as rubber hardness, tensile strength and compression set; all unqualified raw materials are rejected. During production, key dimensions including product flatness, outer diameter and thickness are sampled batch by batch, and dimensional accuracy is verified using high-precision coordinate measuring machines. In the finished product stage, 100% visual inspection and sampling-based sealing tests are performed, and sealing performance is verified via pressure testing to guarantee zero leakage. We have established a complete batch traceability system: each batch retains production and inspection records traceable to raw material batches and production time, enabling quick identification and closed-loop resolution of any quality issues.

We offer full-dimensional customization services for the Medical Rubber Gasket Seal to fully address the differentiated sealing needs of different equipment. In terms of size, custom outer diameter, inner diameter and thickness are available to precisely match customers' sealing grooves and flange dimensions. In terms of material, options include nitrile rubber, butyl rubber, fluororubber, silicone, etc., selected based on application scenarios to adapt to different media, temperatures and pressure requirements. Product hardness, color and surface texture can also be customized for special installation and usage requirements. For non-standard specifications, we provide rapid mold customization with a sample lead time of 7–15 working days, and new mold costs can be fully deducted from subsequent bulk orders.

The Medical Rubber Gasket Seal adopts standard industrial export packaging suitable for long-distance sea and air freight. Inner packaging uses sealed plastic bags, packed by specification in fixed quantities to avoid friction and extrusion; the middle layer uses custom corrugated cartons with internal buffer pads to prevent deformation during transportation; outer cartons are made of five-layer reinforced corrugated board, secured with high-strength strapping, delivering excellent compression and moisture resistance. The outer cartons are clearly printed with product name, specifications, quantity, production batch number and storage warnings, and are accompanied by documents including packing lists, product certificates and material test reports. We support EXW factory delivery and can also arrange shipment via customers' designated freight forwarders. Conventional orders can be shipped within 7–15 working days.
