As technology advances in the medical industry, so do the regulations for safety and hygiene. Medical seals have become more effective and durable to prevent contamination, contain harsh chemicals, and withstand varying temperatures. These seals are vital to every pharmaceutical machine or medical device where fluids and gasses are transferred.

Medical seals must be resistant to harsh or toxic chemicals and be manufactured with the highest quality to withstand exposure. Medical seals should have a high level of biocompatibility which indicates whether or not the seal will react to living tissue, bodily fluids, drugs, or medical fluids. It is critical to evaluate the performance requirements of the seal and select a material that will prevent unwanted reactions during medical applications.

Types of Medical Seals

Medical seals protect both patients and devices from harmful leakages. You must understand the application before you can select the correct seal. This means you must consider any potential contact, motion, temperature, or pressure the device will encounter as well as its expected lifespan. There are a variety of medical seals used in both the medical and pharmaceutical industries. MSP Seals offers some of the most frequently used medical seals, including:


O-rings are widely used due to their economic advantages. They are circular gaskets with the ability to seal in any direction to protect against air and fluid leaks. O-rings are do not require tightening, making them easy to install and maintain. They are durable with the ability to withstand a range of temperatures, tolerances, and pressures.

Lip Seals

Also called oil seals or rotary shafts, lip seals are durable, flexible rings made of elastomer. Lip seals are wear-resistant, making them ideal for securing the barrier between moving and stationary components in a machine. By sealing gaps in machinery, lip seals prevent contaminants from entering the system and device lubricants from leaking.


Gaskets serve an important function in many medical devices. They are used to create seals between two components, or flanges with flat surfaces, to prevent leakage.

Medical Seal Applications

Medical seals are used whenever liquids or gasses are pumped, transferred, contained, drained, or dispensed. Medical-grade seals come in a variety of shapes and sizes to accommodate complex applications in the medical industry. It is critical to protect patients and the devices they depend upon from harmful leakage. Medical seals are used in common devices such as medical pumps, feeding devices, implant materials, IVs, and respiratory devices.
