When a sealing device can make the difference between life or death, failure is never an option. Medical seals require careful design, the right materials and precise execution to help save lives. Apple Rubber engineers work with customers one-on-one, from design and prototype to production and testing, to ensure every product meets exact specifications.
Trusted Medical Seals
Today’s advanced medical technology has placed rigorous new requirements on medical equipment and devices. That’s why Apple Rubber is committed to providing quality sealing solutions that meet the highest industry standards.
Medical grade elastomers at Apple Rubber are tested to FDA USP Class VI or ISO 10993 protocols to ensure they are suitable for critical environments. The medical grade elastomers we use feature improved chemical resistance, excellent heat resistance and low permeability to gas. Our Class 10000 ISO-07 certified cleanroom allows us to consistently manufacture high quality components directly from our facility. For even greater peace of mind, our engineers can provide quality documentation from First Article for full IQ OQ PQ.
Apple Rubber develops medical parts and seals for a wide range of applications, including seals for ventilators and other medical appliances, IV components, medical pump seals, o-rings for testing consumables, feeding devices and implant materials.
Standard and Non-Standard O-Rings
Apple Rubber carries a large range of standard and non-standard sized o-rings in stock at all times. To keep up with the increasing demand of microminiature seals for precise medical instruments, we’ve developed the MicrOring®, which can be designed in over 2,000 sizes—the smallest measuring at only 0.38 millimeters and the largest reaching 1.0 mm.
Our medical o-rings feature tighter tolerances and ultra-low defect rates. With fully automated inspection machines, we can produce 100 percent inspected parts for both fine defects and size.
Custom In-House Prototyping
Medical seals often require custom sizes and shapes. With in-house prototyping, our engineers are able to get a careful look at design details and smooth out production to avoid scheduling, budget, quality and regulatory specification risks down the line. Our advanced technology includes 3D CAD, CAM and CNC tooling to create the exact prototype you need while saving extra time and associated costs.
We carry a variety of rubber compounds in our facility that are designed for critical medical seals, including silicone, fluoroelastomer (FKM) and ethylene-propylene (EPDM). Our engineers can custom color-match the material you choose, as well as modify polymers to better suit the environmental factors of your application, such as friction or chemical resistance.
Sealing solutions for medical applications require highly precise designs that meet strict industry regulations. In many cases, a patient’s life depends on the success of a single medical seal. Apple Rubber medical seals are designed with the highest quality materials and carefully executed to ensure every seal is aligned with medical standards.
To solve the increasing demand of micro miniature sealing solutions for precise medical instruments, Apple Rubber developed the MicrOring®. A MicrOring® seal can be defined as any o-ring that measures less than 1 millimeter in either inside diameter or cross section. We offer over 2,000 sizes of MicrOrings®, the largest with an inside diameter of 1 millimeter (0.039 in) and the smallest with an inside diameter of .20 millimeters (0.015 in).
From the most exotic seals to intricate sizes, every custom molded medical seal is designed and manufactured to meet your exact specifications. With our advanced processes and sophisticated tools, our engineers can drastically reduce design and development cycle time. If you’re looking to test a custom design before production, we offer in-house prototyping for sealing solutions of any shape or size. Our engineering team will work with you one-on-one to ensure your custom prototype meets your exact specifications.
At Apple Rubber, we offer compression, transfer and injection molding in-house. Our advanced technology includes state-of-the-art molding machines that always provide high-quality parts for our customers. Our molding capabilities rely on sophisticated processes, software and tooling to build custom rubber molds for countless medical applications.
Apple Rubber has earned a reputation for solving tough sealing problems associated with smaller designs. Even our competitors have recommended us for challenging microminiature applications that were beyond their capabilities. To keep up with increasing demand, Apple Rubber developed the MicrOring®: an o-ring that measures less than 1 mm in either inside diameter or cross section. From precise medical instruments to aerospace and fiber optics, MicrOring® seals are an effective choice for a wide range of miniaturized applications.
Download White PaperLancaster, N.Y. (April 13, 2021) — Apple Rubber is proud to celebrate its 50th anniversary in the industry. Founded in 1971 in Lancaster, NY, Apple Rubber began as a small manufacturer of rubber sealing solutions. Through 50 years of innovating and responding to the changing needs of customers worldwide, Apple Rubber has introduced a variety of new products, expanded material sciences and developed expert engineering services.
Apple Rubber works with customers from the initial design phase, including either single cavity or prototype, to transition into a multi-cavity production tool with full process validation. When a customer came to us with a standard o-ring design, our engineers worked with them one-on-one to ensure that the design, functionality and production path was integrated properly. Through extensive o-ring testing, we identified several design errors and solved them before the product reached production.
New applications are pushing the limits of low-temperature performance in standard rubber compounds. In most cases, formulation changes must be made to meet these new criteria. As temperatures drop, many rubber materials begin to increase in hardness and resistance to deformation, which can result in leakage. Apple Rubber engineers took a closer look at three common polymers, Nitrile Rubber (NBR), Silicone (SL) and Fluorocarbon (FKM) to find ways to improve their performance at low temperatures.
Rubber o-rings, sanitary gaskets and tri-clamp gaskets are widely used in food, beverage and medical processing plants. In the brewing industry, certain rubber formulations can change the taste of different types of craft beer. Apple Rubber tested five common FDA compliant materials with five different craft brews to find out which o-rings were best for brewing.
