Year Founded:

Established in 1988 in Sheffield, Flexseal's core business was to design, manufacture and assemble flexible couplings for the repair of sewer and drainage systems.

In 1991 Flexseal increased capacity with the acquisition of a 1022m2 factory to meet the increasing demand for flexible couplings, which was then followed by further expansion into an 1858m2 factory.

Flexseal generated considerable growth across domestic and international markets during the late 1990's. A new state of the art purpose built production facility (2787m2) was commissioned in Wombwell in Barnsley in 1998 to meet the continued development, and marked our 10th year anniversary. Over the ten-year period the number of employees had increased from two to over sixty.

In 2002, Flexseal were acquired by the US owned Fernco Group, and a global group was created that supplied the most extensive range of flexible couplings throughout the world. Fernco was originally established in Ferndale in Michigan, USA in 1964 and soon developed an enviable reputation of producing couplings. Phenomenal growth during the 1970's led to the business purchasing a 9290m2 building in Davison in Michigan, and to the introduction of the first injection moulding machine in 1978.

The growth continued into the 80s and 90s with investments being made in further injection moulding capabilities, process improvements, and distribution and manufacturing facilities. Innovations such as flexible elbows and tees made the Flexseal name link to the highest quality of product and service in the industry.

Flexseal remain focused on product innovation, forging strategic partnerships and expanding into new international territories. For our latest news and product updates, please visit our news pages.

Flexseal are part of the world leading Fernco group of companies, with our head office in Michigan, USA.

Over the years, the group has grown to owns and operate companies in 8 countries worldwide, with distribution partners into many more - all are dedicated to supply of the highest quality flexible couplings for drainage and plumbing applications.

The Fernco Joint Sealer Company was established in 1964 by an individual contractor looking for a time saving and reliable solution to his pipe connection needs. Mr. Zopfi developed a pre-formed tar donut for use on his own jobs in the Detroit area during the late 1940's. Word spread of his invention as other contractors wanted to take advantage of this labour saving product and purchased them directly from Mr. Zopfi, who set up a small shop in a garage behind his plumbing business.

Since this beginning, Fernco has continued to grow into more markets and has continued to develop innovative, reliable and easy-to-use products. Fernco expanded into Canada and then to the Western USA with a location in Reno, Nevada. In August, 2002, Fernco, Inc. acquired Flexseal Couplings, the leading manufacturer of flexible couplings in the European market. This meant the group had access to a well-established customer base throughout all of Europe, and additional manufacturing capacity in the UK and Germany. Australia, Mexico and Brazil followed, with a most recent move into France.

From a company that started with one individual in 1964, the Fernco Group has become the most well established and trusted manufacturer of flexible couplings in the world.
