VACCO Industries, headquartered in South El Monte, California, has long been a cornerstone of the region’s industrial and engineering landscape. The company, known for producing highly engineered valves, manifolds, regulators, and filters, has supplied mission-critical components to both the space and naval defense sectors for over 70 years. Its location in South El Monte is more than a business address—it represents a longstanding relationship with the local workforce, community institutions, and Southern California’s broader aerospace corridor.
Supporting Innovation in Space and Defense
Founded in 1954, VACCO has played a key role in shaping the engineering profile of South El Monte, evolving from a specialized valve manufacturer to a global supplier of complex fluid control systems. The company’s products are widely used in U.S. Navy submarine systems, NASA spacecraft, and other high-reliability aerospace applications. By remaining in South El Monte, VACCO has continuously contributed to the city’s reputation as a hub for advanced manufacturing.
Their 135,000-square-foot manufacturing campus on Klingerman Street houses both design and production facilities, allowing for vertically integrated operations. This setup has helped VACCO become a critical supplier for U.S. government defense and space contracts. The company’s success has also meant stable employment for hundreds of local workers and consistent investment in South El Monte’s industrial development.
Community Jobs Grow at VACCO South El Monte Facility
VACCO’s presence has created skilled job opportunities in engineering, machining, quality assurance, and systems integration—many of which are filled by residents from South El Monte and surrounding communities. The company has participated in workforce development programs in partnership with local schools and technical colleges, offering internships and training opportunities that prepare students for careers in science and technology.
According to previous community announcements, VACCO has supported STEM initiatives, hosted facility tours for student groups, and engaged in local outreach events that strengthen ties between the aerospace sector and the educational institutions in the San Gabriel Valley. Their technical staff has frequently participated in speaking engagements and advisory roles to help shape the curriculum at nearby vocational programs.
Transition to RBC Bearings
In a strategic move that underscores the growing importance of the space and naval defense markets, RBC Bearings Inc. announced on May 20, 2025, its acquisition of VACCO for $310 million. The transaction is expected to close this summer, and the company will be integrated into RBC’s Aerospace and Defense segment. The acquisition is seen as a way to expand RBC’s footprint in South El Monte and further reinforce its commitment to U.S.-based precision manufacturing.
“Combining VACCO’s expertise in highly engineered valves, regulators and manifolds with RBC’s broader portfolio will enable us to better serve the evolving needs of customers,” said Dr. Michael J. Hartnett, RBC’s CEO.
Future Outlook Strong for VACCO South El Monte Team
Despite the ownership change, VACCO South El Monte will continue to serve as a major regional employer and innovator. RBC’s plans to integrate VACCO’s operations into its global network are expected to bring additional investment to the South El Monte facility, possibly increasing its capacity and enhancing job opportunities.
The acquisition also strengthens South El Monte’s economic positioning within the growing national focus on domestic aerospace and defense production. As the space and defense sectors continue to expand, companies like VACCO are essential to both national priorities and local prosperity.
In a city known for its small-business backbone and manufacturing tradition, VACCO remains a testament to how a local company can achieve global reach while staying committed to its community roots. Its continued presence ensures that South El Monte will remain at the forefront of innovation in some of the most advanced engineering fields in the world.
