ABOUT US

At Purosil, we’re both global and local – a fourth-generation family business, with manufacturing / sales / distribution on 4 continents.

We bring the ownership family’s values of service and quality to our customers, along with the global power and technical expertise to solve any supply needs – large and small.   When you choose Purosil, you choose world-class quality, with local support and attention to your company’s needs.

Established in 1958, Purosil specializes in producing silicone rubber products for the heavy-duty diesel, EV, and Hydrogen specialty hose markets.

Purosil was purchased by the Garrett family, owners of the Mission Rubber Inc. group of manufacturing companies, in 2002, to augment our Transportation Rubber division.  Our group of companies began with a modest family plumbing business in Los Angeles in the late 1940s and expanded into the manufacturing of sustainable clay products and rubber plumbing products.  Our rubber division further grew to include transportation in the late 1990’s and early 2000s, which led to the acquisition of Purosil.

In 2005 Purosil moved to the current California factory and corporate campus east of Los Angeles. In 2019 we opened our India factory on an aerospace manufacturing campus in Belgaum, Karnataka.  Our European sales and distribution branch opened in 2022 in the Netherlands. We have three family-member owners operating the three main Purosil locations, and the entire parent MCP Group has remained wholly family-owned and operated since its inception in 1950.

Today, Purosil has over 200 employees globally, and 250  thousand combined square feet of manufacturing – 23,226 sq meters.   We serve the heavy-duty truck, bus, and coach sectors, as well as the construction equipment, farm equipment, U.S. military vehicle, stationary generator, and marine markets. We manufacture High Performance Silicone Hose and complete Assemblies, and Silicone and EPDM Knit Hose.

Purosil specializes in Silicone hoses and assemblies.   With decades of experience in these products, we bring both Polymer Chemistry, and Hose Design and Rubber Materials Engineering expertise to everything we do.

Our CEO, Dr. Thomas Garrett, PhD chose to take charge of Purosil because of his lifelong study of Polymers and their applications.   With a doctorate in Chemistry from Stanford, he has served as CEO since 2005.

We employ 3 Polymer Research Chemists, 4 Lab Technicians, 7 dedicated Quality Personnel and 9 total technical staff in Design and Management across our sites.

Purosil does Extrusion, Molding, Knitting, Formed (Shaped) Mandrel, Bias Wrap, and Bias Cutting.  We work with VMQ, EPDM, SBR, NR, CR, FKM, and many other polymers.

Purosil does our own in-house Design and Engineering, Mixing and Compounding, Hose Manufacturing, Kit Assembly, and final testing.  This allows us to control every aspect of our end product, to produce consistency and reliability.   We manage a diverse supply chain of base material, and then design and control our own formulations, to be able to work with any base silicones in the world.  For us, this meant that when others struggled to maintain quality or supply in the global supply chain crises of recent years, Purosil never stopped supply to our customers, and still maintained our high standards of quality.

Purosil’s mission is to offer the highest quality hoses, at globally competitive prices, with service & sales across the US, Europe, and India, and hands-on design support for all regions.
