Parker O-rings Meet The Needs Of The Medical Industry

Medical Applications For O-Rings

In the medical industry, O-rings and seals play an important part in ensuring that equipment runs properly. From instruments used by doctors and dentists, to large equipment such as kidney dialysis machines, to analytical and testing equipment, high quality O-rings resistant to temperature, chemicals, and electrical interference play a role in providing high-quality medical care.

Requirements For Medical Grade O-Rings

Medical applications often use seals, extruded profiles, spliced and fabricated products and custom molded or machined shapes in addition to O-rings to cushion, seal, isolate chambers, and minimize vibration in delicate instruments, implants, components, and equipment. Many of these O-rings and seals are engineered to meet specific performance requirements in both design and materials, such as:

  • Must perform in static and dynamic applications
  • Superior sealing to prevent fluid or gas loss
  • Flexible enough to use in multiple applications, with custom-designs available upon request
  • Proper compression set to ensure that O-ring will return to original thickness after use, despite temperature variations, squeeze over time, and contact with fluid
  • Cost effective
  • Compatible materials to meet specs developed for life science applications
  • Compliant with approvals and standards required in the industry

Meeting Standards For Medical Grade Products

O-rings and other seals used in medical grade products must often meet requirements from the FDA and other bodies to verify that they are properly manufactured for use in medical devices and other life-sciences applications. This prevents contamination during manufacture, and also to prevent failure during usage which could cause equipment or a process to shut down. Some of the standards that might apply to materials and manufacturers include:

  • United States Pharmacopeial sets standards for medicines and healthcare products produced in the US. USP VI-approved elastomers meet standards for biological reactivity and physicochemical properties when used in medical devices that require contact with human or animal bodies or bodily fluids, as well as medical devices.
  • FDA, Title 21, Part 177.2600 also covers elastomers or rubber products used for repeating usage in medical, farmer, biochemical, and food industries.
  • ISO standards, such as 10993 for medical devices and 14644-1 Class VII which regards clean rooms for manufacture.

Materials To Do The Job

Parker O-rings and gaskets offered by Performance Seals are made from elastomers that meet FDA and USP VI standards. Common materials include:

  • Ethylenepropylene, which is resistant to many chemicals
  • Fluoroelastomers, which are resistant to heat and chemicals
  • Perfluoelastemers, which are resistant to high heat and chemicals even under prolonged conditions
  • Nitrile, which has good mechanical properties, resistant to greases and lubricants, and affordable
  • Silicone, which is resistant to ozone, weathering, and aging, and capable of functioning under a wide temperature range
  • Thermoplastics, which is a harder plastic material

Applications In Disposable Products And Medical Equipment

With a wide variety of materials and infinite design options, Parker O-rings rind their way into a variety of disposable medical supplies and equipment:

  • Catheters
