Currently registered as a privately held, woman owned small business, Da/Pro Rubber, Inc. was  founded in 1960 when Charles Daubenberger Sr. developed a unique low-pressure press for compression molding rubber, allowing Da/Pro Rubber to offer precision, virtually flash free molding of elastomers to its customers.

Starting from a site in Santa Monica, CA, the company moved to Van Nuys in 1966.  As sales grew, the company opened a manufacturing facility in Tulsa, OK in 1976, which serves as their headquarter operation today.

In 1991, the company further expanded its manufacturing capabilities to the international arena in Asia, when a manufacturing facility opened in Singapore.


To accommodate key customer requests, Da/Pro Rubber, Inc. added a Class 10,000 cleanroom molding facility at their Tulsa site in 1995. Liquid silicone rubber injection molding capabilities were added to the Tulsa facility in 1997.

The California molding operations moved into a world class 30,000 square ft. manufacturing facility in Valencia, CA in 2000. Liquid silicone rubber (LSR) injection molding capabilities were added to the Singapore and Valencia operations in 2001. 

On November 01, 2005, Da/Pro expanded operations to the Northern U.S., opening a 30,000 square foot plant in Newburyport, Massachusetts.  

Shortly after that, in 2006, Gretchen Brauninger assumed leadership as Da/Pro Rubber, Inc.'s CEO, and Mr. Daubenberger assumed assignment as Chairman of the Board.

In 2008, Da/Pro opened a 40,000 square ft., state-of-the-art facility, which allowed for introduction of LIM (liquid injection molding services) as well as additional molding activities. This facility provides full service quality control, inspection, on-site LIM engineers, and full shipping capabilities.

Da/Pro Rubber has been providing rubber-molded parts to international markets for over 40 years with a regional sales force in the U.S. and sales representatives located in Scotland, Germany and Singapore.

Today, Da/Pro holds four manufacturing facilities within the U.S. and an international manufacturing facility in Singapore. Each of these locations proudly holds ISO-9001 certification.
