SantoLight
Chemically inert, low-viscosity optical-grade fluids for sensitive optical assemblies.
Synthetic Lubricants & Specialty Fluids for Extreme Applications
Seven PPE-based product families engineered for the operating conditions where conventional mineral and PAO lubricants fail — extreme temperature, ultra-high vacuum, radiation exposure, and demanding traction environments.
Engineered for Extreme Conditions
Custom Formulated Solutions
ISO 9001:2015 Certified
Built on Polyphenyl Ether (PPE) Chemistry
Every SantoLubes product family shares a common foundation: advanced polyphenyl ether base chemistry, formulated and manufactured under ISO 9001:2015 quality management at our Spartanburg, South Carolina facility. That chemistry is what delivers thermal stability to 450°C (840°F), vacuum performance down to 5×10-10 torr, and chemical and radiation resistance that conventional fluids can’t match.
Each product family below is engineered for a distinct performance requirement — vacuum, traction, base oil viscosity, connector protection, optical clarity, radiation resistance, or PFAS-free compliance. Not sure which fits your application? Our applications engineers will review your operating conditions and recommend the right grade at no obligation.
SantoRad
Specialty synthetic fluids formulated for stability in high-radiation environments.
ACCL
Anticorrosion connector lubricants that protect electrical contacts from corrosion and fretting.
SantoVac
High-vacuum pump fluids for maximum pump life and low volatility performance.
SantoTrac
Advanced traction drive fluids built for high load and extreme conditions.
ultEbase
Ultra-low EHD shear synthetic base oils for superior efficiency and thermal stability.

What products does SantoLubes offer?
SantoLubes offers a family of PPE-based synthetic lubricants and specialty fluids: SantoVac high-vacuum pump fluids, SantoTrac traction drive fluids, ultEbase synthetic base oils, ACCL anticorrosion connector lubricants, SantoLight optical-grade fluids, and SantoRad radiation-resistant fluids. Each is engineered for a distinct performance requirement where conventional mineral and PAO lubricants fail.
What chemistry are SantoLubes products based on?
Every SantoLubes product is built on advanced polyphenyl ether (PPE) base chemistry. This shared foundation delivers thermal stability up to 450°C (840°F), vacuum performance down to 5×10⁻¹⁰ torr, and chemical and radiation resistance beyond the reach of conventional fluids. All products are formulated and manufactured under ISO 9001:2015 quality management at the company's Spartanburg, South Carolina facility.
What is SantoVac used for?
SantoLubes fluids are engineered for conditions where conventional lubricants fail — from vacuum pumps in orbit to gearboxes underground. Their PPE-based chemistry delivers resistance to extreme temperatures, high loads, radiation, corrosion, and chemical exposure, which is why OEMs and operators specify them for the most demanding applications. The product line has been in service for more than 30 years.
What is the difference between SantoTrac and ultEbase?
SantoLubes fluids are engineered for conditions where conventional lubricants fail — from vacuum pumps in orbit to gearboxes underground. Their PPE-based chemistry delivers resistance to extreme temperatures, high loads, radiation, corrosion, and chemical exposure, which is why OEMs and operators specify them for the most demanding applications. The product line has been in service for more than 30 years.
