Over 110 Years of Excellence

Feel free to learn about our history in delivering excellence for over 110 years!


English emigrates, brothers Douglas and William Radford founded the company in downtown Los Angeles, domiciled in a facility adjacent to the Los Angeles City Jailhouse. During its infancy, oil exploration in Southern California was booming and WARCO BILTRITE directed its efforts on the manufacture of molded rubber parts to serve the burgeoning oil industry.


West American hits Hollywood: our original factory is featured in the background of Harold Lloyd’s silent movie classic Take a Chance.


WARCO BILTRITE experienced a set back with a devastating fire, which for many companies would have proved catastrophic; but not for WARCO BILTRITE. Thanks to the help of other rubber manufacturers on the West Coast, WARCO BILTRITE’s orders continued to be filled. Today WARCO BILTRITE gratefully acknowledges and warmly remembers those good companies and people who supported it during such a difficult time.


At this point, the company’s ownership consisted of ten shareholders. Over time however, two of the gentlemen, Mr. Sam Eisenberg and Mr. Paul Sampsell would buy out the interests of the other eight. Messrs. Eisenberg and Sampsell operated WARCO BILTRITE from 1952 to 1977. The industry will remember them as hard working, honest and dedicated men who each contributed greatly to the growth of the rubber industry in Southern California


The company outgrew its facilities in downtown Los Angeles; choosing to relocate to its current location on eleven acres on Main Street in Orange, California


WARCO BILTRITE acquired several existing rubber companies including, Extruded Rubber Products, Semco Rubber Company, and Stoner Rubber Company. A new chapter unfolded as WARCO BILTRITE began the Extruded Rubber Division. It was during this time that the first Hemstreet came to WARCO BILTRITE: Alda Katherine Hemstreet, mother of Steve and Ken Hemstreet


It was this year that Steve Hemstreet began his career with WARCO BILTRITE. From 1971 to 1977, Steve held eighteen different job functions throughout the factory and the laboratory. As in previous years, the company continued to invest in new equipment; resulting in WARCO BILTRITE becoming a leader in rubber injection molding and pioneering advancements in molding technologies such as rubber-to-metal bonding, a discipline it continues excelling at today.


Harrison Industries, a privately held manufacturing conglomerate, led by Benjamin F. Harrison in Birmingham, Alabama acquired WARCO BILTRITE. Steve Hemstreet became an officer of the company, Ken Hemstreet joined the WARCO BILTRITE family, and Conrad Blackerby of Harrison Industries relocated from Alabama to become WARCO BILTRITE’s President. At that time the company continued to grow at a tremendous rate; as a result, a Louisville Distribution & Customer Service Center was established to enhance the growing sheet rubber products business and provide support to its expanding customer base east of the Mississippi River.


Technical Equities Corporation, a diversified publicly traded holding company acquired WARCO BILTRITE from Harrison Industries in an all cash transaction. WARCO BILTRITE continued its impressive sales growth and capital expansion, including the purchase of state-of-the-art production equipment for continuous vulcanization of extruded rubber products.


Conrad Blackerby and Steve Hemstreet acquired the company. Between the years of 1986 and 1998, WARCO BILTRITE experienced tremendous growth. The company operated dedicated manufacturing divisions which included: Molded, Extruded, Sheet, Performance Processing Company (custom mixed silicones) and WPP, a large volume intermediary of a variety of rubber materials.


Yet another chapter unfolded for WARCO BILTRITE. Industrial Growth Partners (IGP), a San Francisco based private investment firm, partnering with WARCO BILTRITE’s management, acquired the assets of WARCO BILTRITE.


Steve Hemstreet, along with his brother, Ken, re-acquired WARCO BILTRITE from IGP November 9th.

The U.S. House of Representatives honored WARCO BILTRITE with an award for “Outstanding Business of the Year, 2005,” in recognition of outstanding and invaluable service to the City of Orange.

Later that same year, WARCO BILTRITE announced its acquisition of Ripley, Mississippi based Biltrite Corporation’s sheet rubber and rubber matting business; a move that positions WARCO BILTRITE as the largest US based sheet rubber maker in North America, further entrenching its foothold in the oil, military, transportation, construction and food services industries.

The two strategically located manufacturing plants remain integral to facilitating the company’s future growth. Biltrite’s highly trained and dedicated staff coupled with its expansive 400,000 sq ft manufacturing facilities, combined with WARCO BILTRITE’s 150,000 sq ft facilities and devoted personnel create a market presence of unparalleled capability, service and commitment.
