Recent Milestone
USAF OTA Prototype Contract
OILKLEEN was awarded a USAF Other Transaction Authority (OTA) Prototype contract to design specialized hydraulic power units for USAF Test facilities. This program directly applies our proven high-pressure hydraulic and fluid-cleanliness expertise to support critical aerospace testing and operational readiness for the United States Air Force.
What makes us special
Core Capabilities
Oil Flushing and Chemical Cleaning
Advanced high-velocity oil flushing combined with specialized chemical cleaning processes for aerospace fluid systems, removing varnish, particulates, and legacy contaminants to restore and maintain peak performance.
Specialized Hydraulic Design & Repair
We specialize in servo-controlled flight systems, lube oil circuits, landing gear hydraulics, and high-performance hydraulic power units where absolute reliability and cleanliness are essential in aerospace productivity.
MIL SPEC Lubricants - From Submarines to Spaceships
Our portfolio includes MIL-SPEC lubricants and non-varnishing synthetic fluids proven on US Navy submarines and adapted for aerospace and space platforms. They deliver thermal stability, oxidation resistance, and long-term varnish-free performance in extreme environments — from deep sea to orbital and hypersonic operations.
