Download the Parker O-Ring Handbook

For more than 65 years, the Parker O-Ring Handbook has been an engineering staple of the sealing industry.

.... and now you can download it for free.

In 2015, Parker Hannifin Corporation launched an interactive digital reference guide to enhance and broaden the customer reach of the existing Parker O-Ring Handbook, the Parker O-Ring eHandbook.

“I’m constantly amazed and honored at how often I run across it in unexpected places,” says Dan Ewing, senior chemical engineer and materials manager at Parker's O-Ring division, “I've come to expect to see a well-used copy sitting on a customer's desk, but I'm pleasantly surprised when I find it cited in academic papers, referenced in reports written by government agencies and discussed in industry association meetings.”

Since its debut in 1957, the handbook has become a fixture on the reference shelves of engineers and seal specifiers worldwide.

"Parker's O-Ring Handbook is one of the world's most complete reference books for everything and anything related to the technology and application of O-rings," said Steven Weinzierl, Ph. D., Parker's global e-business customer support manager,

"It is downloaded thousands of times a month from Parker's website, making it one of Parker's most downloaded knowledge assets."

“The new eHandbook takes the next step in enhancing the customer experience by transforming the static PDF version of the handbook into an interactive and more user-friendly tool," Ewing said.

Key Components:

  • Short, engaging animations
  • Snippets of real material test procedures
  • Direct links to accelerate the sales process
  • Online Chat with an Engineer capability within each page
  • Design analysis via Mobile inPHorm™ (Parker’s O-Ring Calculator)

The O-Ring eHandbook is expected to bridge the generation gap, filling the need for all learning and reference styles. The original formats of the printed catalog and searchable pdf will still remain available via Parker’s Catalog Services and the O-Ring Division website.

How to Use the Parker O-Ring Handbook

The O-Ring eHandbook will provide visual learning, interesting excerpts and summarized information that makes finding what you need effortless. New content will be added as needed and because the format is web-based, content updates will become quicker and more efficient.

"I like the simplicity the eHandbook brings to O-ring design and material selection," says Dorothy Kern, Parker O-ring division applications engineering manager. "The original handbook is rich with details for all elements of O-ring design, but 292 pages can be overwhelming to a new engineer. The eHandbook simplifies the main design concepts and utilizes updated graphics to illustrate just the highlights, making it a great resource."
