Since 1955, Precision Associates Inc. has been proud to offer top-quality precision-molded rubber goods.

We established our reputation by designing top-quality O-rings for everyday use. In 1956, cofounder Arnold Kadue noticed how ubiquitous O-rings were becoming in contemporary applications. However, these O-rings were also constructed from prohibitively expensive materials, and he directed PAI to find ways to lower their cost of production. By 1957, PAI had perfected fifteen different varieties of the AN 6227 O-ring for public use, and this material continues to appear in many industrial applications today.

PAI has grown exponentially since then. Since perfecting numerous inventions and patents in the mid-1960s (like the Multiseal, a low-friction dynamic seal for use in O-ring grooves), PAI has undergone tremendous development in both business and process efficiency from its inception.

PAI is Your Source for Custom-Molded Rubber Parts and Products

PAI offers top-of-the-line engineering services that span the production process from initial part design through final delivery. We manufacture products to order based on your specifications, and we rely on our wealth of expert knowledge and industry-grade tools to help us get the job done.

Our on-site tool shop allows for economic options when it comes to prototyping, 3D models, and sample parts. We visually inspect each rubber part to ensure that it’s free of defects, and we organize our production processes to maintain traceability throughout manufacturing.

PAI Offers Custom O-Rings and More

PAI builds O-rings from over 1,000 rubber compounds that we develop in-house. Many applications today present challenging part specification requirements, but our team is expertly prepared to work with you to find the perfect O-ring design. 

Many industries benefit from the use of custom-molded rubber parts every day. For example, the oil and gas industry require rubber parts that can withstand extreme temperatures, powerful vibrations, and chemical exposure. Oil and gas pumps rely on O-ring and sealing solutions to deliver exceptional performance in extreme conditions sealing harsh chemicals at high temperatures. Additionally, everyday electronic items like laptops and cell phones require rubber sealing to protect components from dust and water contamination. 

PAI: Your Source for Custom Rubber Solutions


PAI offers not only standard and custom O-rings but a host of other custom-molded rubber parts. We design custom rubber components geared for medical, oil & gas, electronics, and various other applications.
