About VACCO Industries

VACCO Industries is a US manufacturer of precision fluid control components and integrated propulsion subsystems for spacecraft and defense applications. Founded in 1954 and headquartered in El Monte, California, VACCO has over 70 years of heritage manufacturing flight-quality propulsion hardware for NASA, DoD, and commercial satellite missions.

VACCO's space products fall into two main areas: integrated micro-propulsion systems for small satellites (CubeSat and SmallSat), and precision fluid control components including latch valves, check valves, relief valves, and pressure regulators for larger spacecraft. Their Micro Propulsion Systems (MiPS) product line offers complete, integrated cold gas, warm gas, and green monopropellant thruster modules designed to fit within CubeSat form factors.

Highlight missions include the ArgoMoon MiPS, which flew on NASA's Artemis I in 2022 as an ESA CubeSat secondary payload, the JPL MarCO MPS that flew on the first interplanetary CubeSats in 2018, and the NASA C-POD system demonstrating on-orbit propulsion for 3U CubeSats. VACCO's Standard MiPS has been selected for dozens of commercial LEO constellation satellites.

VACCO Industries was acquired by RBC Bearings in 2021. The company operates under its established brand and continues to serve the space industry from its El Monte, California manufacturing facility. VACCO's propulsion components are designed and tested to MIL-SPEC and aerospace quality standards with full traceability.
