BUILT FOR THE
DEPARTMENT OF DEFENSE.
AVAILABLE TO EVERYONE.
Mercury Hydraulics was founded to design and manufacture hydraulic systems for U.S. Department of Defense contracts. That heritage of precision, reliability, and zero-defect standards is what we bring to every customer — military or commercial.
WHEN YOUR FOUNDATION IS THE PENTAGON, THE COMPETITION NEVER HAD A CHANCE.
Most hydraulic repair shops were built to serve commercial customers from the start. Their tolerances, their quality standards, and their processes were calibrated to what the commercial market required.
Mercury Hydraulics was built differently. We started as a hydraulic systems design and manufacturing company serving Department of Defense contracts — where the tolerances are tighter, the documentation requirements are stricter, and the consequences of failure are measured in lives and national security, not just dollars.
When we expanded into commercial markets, we didn't lower our standards to match the competition. We brought our DoD standards with us — and we dominated from day one because the bar was already set so high.
That's why aerospace companies, superyacht operators, defense contractors, and RV owners across the country choose Mercury Hydraulics. Not because we're the cheapest option — but because when something absolutely has to work, they know where to go.
"The quality of work coming out of Mercury Hydraulics is unlike anything else in the market. They operate at a level most shops simply don't reach."
FROM THE PENTAGON TO EVERY INDUSTRY
Born from the Department of Defense
Mercury Hydraulics was established as a hydraulic systems design and manufacturing company serving Department of Defense contracts. From day one, our work was held to the most demanding standards in existence — military specifications, zero-defect tolerances, and systems that had to perform flawlessly in mission-critical environments where failure was not an option.

Elite Standards Meet Commercial Markets
With a foundation built on defense-grade engineering, we began expanding into commercial and industrial sectors. The results were immediate. When you're trained to build hydraulic systems for the Department of Defense, every commercial job feels like a different level. Our competitors were building to commercial tolerances. We were building to military ones. The difference was obvious from the first job.

The Standard Others Measure Against
Today, Mercury Hydraulics serves aerospace, marine, defense, RV, and industrial customers across the country — and internationally. Companies like L3 Harris, Space Coast Marine, and customers from as far as Buckingham Palace trust us because we never lowered our standards when we left the defense world. We brought those standards with us, and we apply them to every job, regardless of size.

THE PRINCIPLES WE WERE BUILT ON
Military-Grade Standards
Every component we touch is held to the same zero-defect philosophy we developed building systems for the Department of Defense. There is no 'good enough' at Mercury Hydraulics.
Precision Over Everything
We move fast — but never at the expense of accuracy. Our machining tolerances, seal fits, and pressure ratings are measured and verified, not estimated.
Emergency Capability
Defense work taught us that equipment doesn't break on a schedule. We offer 24/7 emergency service because downtime costs real money, and our customers can't afford to wait.
Deep Expertise
Our technicians aren't generalists. They are specialists in hydraulic systems who have worked on everything from spacecraft ground support equipment to superyacht steering systems.
FROM SPACE COAST TO BUCKINGHAM PALACE
Our reputation for defense-grade quality has taken us far beyond our Florida roots. We serve customers across the United States and internationally — from aerospace facilities on the Space Coast to marine clients in Europe. When the job requires the highest level of precision and reliability, they call Mercury Hydraulics.
Certifications & Standards
Our work is held to the standards of the industries we serve — from aerospace and defense to marine and industrial. Every repair is documented, pressure-tested, and certified.
Pressure Testing to 10,000 PSI
Every repaired cylinder and assembly is pressure-tested to rated working pressure — and beyond — with documented test results provided on request.
Aerospace-Grade Workmanship
Our technicians apply aerospace-level inspection standards to every job. Dimensional tolerances, surface finishes, and seal fits are verified — not assumed.
Department of Defense Heritage
Mercury Hydraulics was founded on DoD contracts. Military specifications — zero-defect tolerances, full traceability, documented QC — are embedded in our culture.
1-Year Workmanship Warranty
All hydraulic cylinder repairs and rebuilds carry a 1-year workmanship warranty. If a repair fails due to our workmanship, we fix it — no questions asked.
Full Traceability & Documentation
We maintain complete repair records for every job. Aerospace and defense customers receive full documentation packages including inspection records and test data.
Chrome Plating & Re-Honing Standards
Our chrome plating and cylinder re-honing work meets or exceeds OEM specifications. Surface finish, hardness, and dimensional accuracy are verified before reassembly.
Trusted by the Most Demanding Industries
NASA, L3 Harris, Collins Aerospace, and the Canaveral Port Authority don't trust their hydraulic systems to just anyone. They trust Mercury Hydraulics because our standards match theirs — and because we've never had a comeback on a certified repair.
READY TO WORK WITH THE BEST?
Whether you need emergency hydraulic repair or a custom manufacturing project, you'll get the same defense-grade quality that built our reputation.
