MicrOring® Seals

The leader in micro miniature sealing solutions.

Apple Rubber has earned a reputation for solving tough sealing problems associated with smaller designs. Even our competitors have recommended us for challenging micro miniature applications that were beyond their capabilities. With engineering expertise and advanced manufacturing technology, Apple Rubber 's capability to hold tolerances on micro miniature seals is unsurpassed. In addition, Apple Rubber can develop special compounds to meet the needs of your application.

What is a MicrOring® Seal?

As a general definition, a MicrOring® seal is any o-ring that measures less than 1 mm in either inside diameter or cross section. Apple Rubber offers MicrOring® seals in more than 2,000 sizes, ranging from the largest, with an inside diameter or cross section of .039 in. (1.0 mm), down to .008 in. (.20 mm) inside diameter and cross section - the smallest size O-ring in the world!

MicrOring® seals were developed by Apple Rubber to meet the ever-increasing demand for effective seals in a wide range of miniaturized applications, from precision instruments and medical devices to aerospace and fiber optics. Today's smaller designs can present some big challenges for the design engineer, particularly the tight tolerances required for micro miniature sealing applications.

Beyond O-rings - the big benefits of micro miniature composite seals.

Apple Rubber can ease installation and reduce assembly costs with a composite micro miniature seal custom-engineered for your specific application. Composite seals combine the structural advantages of metal or plastic with the sealing performance of elastomers. They can provide the tighter tolerances and added finesse required in today's micro miniature designs. We can develop micro miniature composite seals - incorporating the seal and another component in one part instead of two – that may even simplify the design of your product.

Apple Rubber is the leader in micro miniature sealing solutions.

Apple Rubber offers the largest selection of micro miniature O-ring sizes available anywhere. Plus, no other company offers more experience and expertise in custom-engineered micro miniature sealing solutions. We are continually adding to our micro miniature experience and have earned a reputation for solving tough sealing problems associated with smaller designs. Even our competitors have recommended us for challenging micro miniature applications that were beyond their capabilities.
