Cerma STM-3 Air Tool Lubricant — Nano Silicon Carbide Ceramic Protection | Restores & Protects All Pneumatic Tools

Stop replacing air tools that should still be working. Cerma STM-3 Air Tool Lubricant uses Nano Silicon Carbide (SiC) ceramic technology to form a permanent micro-ceramic protective seal on all metal parts inside your pneumatic tools — vanes, rotors, cylinders, bearings, and housings. Traditional air tool oils provide a temporary film that wears away within hours of use, leaving metal exposed to moisture, rust, and contaminant breakdown. Cerma is fundamentally different: its SiC particles bond to metal surfaces at the sub-surface level, creating a durable ceramic barrier that restores worn tools and protects new ones, even under heavy daily use. The result is tools that run smoother, last longer, require less maintenance, and resist the moisture infiltration that destroys conventional lubricants. Rustproof, waterproof, no solvents, no PTFE. Available from 1.25 oz bottles for individual tools through 1-gallon jugs for commercial shops. Made in the USA.

  • ✅ Permanent Ceramic Seal: SiC bonds to metal sub-surfaces — protection that doesn't wear off between applications
  • ✅ Restores Worn Air Tools: SiC fills micro-imperfections in worn vanes and rotors, restoring lost performance
  • ✅ Prevents Water Infiltration: Ceramic barrier blocks moisture from compressed air lines that destroys conventional oil
  • ✅ Rustproof & Waterproof: Permanent corrosion protection even in humid shop environments
  • ✅ Reduces Friction & Wear: Ceramic-on-metal contact reduces internal drag — tools spin faster and run cooler
  • ✅ Extends Tool Life: Prevents premature replacement by protecting internal components from wear and corrosion
  • ✅ Contaminant Resistant: SiC seal resists breakdown from oil mist, dust, and shop contaminants
  • ✅ Reduces Maintenance Costs: Less frequent lubrication, fewer repairs, longer tool life
  • ✅ No Solvents, No PTFE: Environmentally safe, won't damage seals or O-rings
  • ✅ Made in the USA
🔬 Why Ceramic Technology Matters for Air Tools

Pneumatic tools are under constant assault from moisture in compressed air lines, abrasive particles, and the extreme rotational speeds of internal vanes and rotors. Traditional air tool oils create a temporary film that depletes rapidly under these conditions — sometimes in hours. Once the oil film is gone, metal-to-metal contact begins, moisture corrodes internal surfaces, and tool performance degrades. Cerma STM-3 changes the equation. Its SiC (Silicon Carbide) micro-ceramic technology bonds to metal at the sub-surface level (Mohs 9.5, nearly diamond-hard), creating a permanent barrier that continues protecting even after the liquid lubricant has dissipated. This means your air tools stay protected between lubrication cycles, through moisture events, and under the heaviest daily use.

📦 Available Sizes

Size Best For
1.25 oz Bottle Individual tool maintenance, try-before-you-buy
6 oz Bottle Small shops, home garages, regular use on a few tools
1 Quart Bottle Busy shops with multiple air tools, fleet maintenance

📋 How to Apply Cerma Air Tool Lubricant

  1. Disconnect the Tool: Disconnect the air tool from the air supply.
  2. Apply Cerma: Add a few drops of Cerma STM-3 Air Tool Lubricant into the air inlet fitting of the tool.
  3. Reconnect & Run: Reconnect the air supply and run the tool briefly to distribute the lubricant through all internal passages and metal surfaces.
  4. Repeat Regularly: Apply before each use or at the start of each work day. Each application strengthens the cumulative SiC ceramic bond on internal surfaces.
💡 Pro Tip: Inline Lubricators

For shops running multiple air tools all day, add Cerma STM-3 to your inline air tool lubricator. The 1-quart and 1-gallon sizes are designed for this application — providing automatic SiC ceramic delivery to every tool on the line, every time they're used.

🛡️ Cerma STM-3 vs. Conventional Air Tool Oil

Feature Cerma STM-3 Conventional Air Tool Oil
SiC Ceramic Technology ✅ Permanent sub-surface bond ❌ No
Protection Duration ✅ Permanent ceramic bond + oil film Temporary — depletes in hours
Moisture Resistance ✅ Waterproof ceramic barrier ❌ Water displaces oil film
Rust Prevention ✅ Rustproof ceramic seal ⚠️ Only when oil is present
Tool Restoration ✅ SiC fills worn surfaces ❌ Cannot restore wear
Contaminant Resistance ✅ Ceramic resists breakdown ❌ Contaminants degrade oil
Cumulative Protection ✅ Builds with each application ❌ Starts fresh each time
PTFE / Solvents ✅ None — safe for seals ⚠️ Some contain PTFE or solvents
💰 The Cost of Not Using Cerma

A quality pneumatic impact wrench costs $200–$800+. Replacement vane kits, bearings, and rebuild kits add up fast. The #1 cause of premature air tool failure is internal corrosion from moisture in compressed air lines — and conventional air tool oil can't prevent it once it depletes. Cerma STM-3's permanent SiC ceramic barrier prevents this corrosion continuously, extending tool life by years and eliminating costly premature replacements. The cost of one 6 oz bottle is a fraction of one tool repair.

❓ Frequently Asked Questions

What is Cerma STM-3 Air Tool Lubricant?
Cerma STM-3 Air Tool Lubricant is a ceramic-enhanced pneumatic tool lubricant powered by Nano Silicon Carbide (SiC) technology. Unlike conventional air tool oils that provide temporary film protection, Cerma's SiC particles bond permanently to the metal surfaces inside your air tools at the sub-surface level, creating a micro-ceramic protective seal. This permanent barrier prevents rust, resists water infiltration from compressed air lines, reduces friction and wear, and restores performance in worn tools. It contains no solvents and no PTFE.
Can Cerma actually restore a worn air tool?
Yes. One of the unique properties of SiC ceramic technology is its ability to fill micro-imperfections in worn metal surfaces. When Cerma STM-3 is applied to a worn air tool, the SiC particles bond into the worn areas of vanes, rotors, and cylinder walls, effectively rebuilding the surface at the micron level. This can restore lost RPM, improve torque output, and reduce air consumption in tools that have lost performance over time. It's not a replacement for tools that are mechanically broken, but it can extend the useful life of tools that have suffered normal wear.
How is Cerma different from regular air tool oil?
Regular air tool oil creates a temporary liquid film between metal surfaces. That film depletes within hours of use, leaving metal exposed to moisture, corrosion, and wear. Cerma adds a permanent layer of protection — the SiC ceramic bonds into the metal sub-surface and stays there regardless of whether liquid lubricant is present. Think of it as two layers of protection: the permanent ceramic seal PLUS the liquid lubricant. Even when the liquid depletes between applications, the ceramic barrier continues protecting.
Why is moisture in air lines such a problem?
Compressed air contains moisture that condenses as the air cools after compression. Even with water separators and dryers, some moisture reaches your air tools. This water displaces conventional air tool oil, exposes bare metal to oxidation, and starts the corrosion process that eventually destroys vanes, rotors, and bearings. Cerma's SiC ceramic seal is waterproof — it's bonded into the metal itself, so water cannot displace it. Your tools stay protected even when moisture gets through.
Can I use Cerma in my inline air tool lubricator?
Yes — and it's an excellent way to deliver SiC ceramic protection to every tool on the line automatically. The 1-quart and 1-gallon sizes are designed for inline lubricator use. Fill your lubricator with Cerma STM-3 and every air tool connected to that line receives ceramic protection with every use.
Is Cerma safe for O-rings and seals in my air tools?
Yes. Cerma STM-3 contains no solvents and no PTFE — two common ingredients in other products that can damage or swell O-rings and seals over time. Cerma is safe for all internal seals, O-rings, and gaskets found in pneumatic tools.
Which size should I buy?
The 1.25 oz bottle is perfect for trying Cerma on a single tool or for occasional home garage use. The 6 oz bottle covers a small shop with a few air tools. The 1 quart is ideal for busy shops with multiple air tools or for use in inline lubricators. The 1 gallon is best for commercial and industrial operations with high tool usage or multiple lubricator stations. A few drops per tool per day is all you need, so even the 1.25 oz bottle lasts many applications.
