Purosil LLC

What Purosil LLC does

Purosil LLC is a vertically integrated manufacturer of high-performance silicone and EPDM hoses and hose assemblies, headquartered in Corona, California with additional manufacturing in Belgaum, India (inside the Aequs Special Economic Zone) and sales/warehousing operations in the Netherlands. Founded in 1958, the company serves six primary industrial verticals: construction equipment, medium and heavy truck, bus and coach, agriculture and industrial, U.S. military, and marine. Purosil holds ITAR certification for U.S. Military vehicle supply and maintains ISO 9001, ISO 14001, and IATF 16949 quality certifications. Its only named customer archetype is U.S. Military vehicle OEMs; other customers are described by industry segment rather than by specific logos.

The company's core technology stack spans from macromolecular chemistry through finished assembly. In-house capabilities include elastomer formulation, fabric braiding and knitting, stamping, injection and compression molding, extrusion, autoclave and oven curing, bias cutting and wrapping, and final assembly. PhD chemists conduct research on thermoset polymer sustainability and develop specialized materials including low-conductivity and anti-corrosive formulations for electric vehicle thermal management and hydrogen fuel cell systems, as well as OAT coolant and hydrocarbon-resistant formulations. The company also sells standard off-the-shelf products through its JAY20 Series e-commerce platform under the BlueJay, RedJay, and GreenJay sub-brands.

Purosil operates a dual-channel go-to-market: enterprise field sales for custom engineered solutions targeting OEM customers with bespoke hose designs and multi-year contracts, complemented by direct-to-consumer e-commerce for standard catalog products. Revenue is generated primarily through custom B2B manufacturing and engineering services; pricing for bespoke solutions is quote-based while standard JAY20 products are sold at listed unit prices. The company's materials development for next-generation ICE, electric, and hydrogen powertrains — combined with its tri-continent manufacturing footprint and military/aerospace-grade regulatory certifications — positions it as a specialty supplier to OEMs undergoing propulsion transitions.
