Thread Sealing Solutions for Critical Applications
Seal and protect threaded connections in demanding environments
Halocarbon’s anti-galling lubricants are engineered to safeguard threaded fasteners, seals, and connectors from mechanical wear and chemical attack. Our InfinX and Halocarbon-branded greases provide exceptional stability in demanding environments where galling, e.g. stainless steel seizing or cold-welding is a risk.
With nonflammable, chemically inert formulations, these greases deliver long-term reliability across a wide temperature range, making them ideal for use in chemical processing, aerospace, energy, and semiconductor manufacturing.
Thread Sealants
Lubricants serve three essential functions in threaded connectors:
- Sealing: They fill the microscopic gaps between threaded connections to prevent gas or liquid leaks when under pressure
- Lubrication: They reduce friction during assembly and disassembly, ensuring proper torque application, preventing thread damage
- Anti-Galling: They lubricate the interface between fasteners such as bolts and the tapped hole, preventing galling or cold welding
Halocarbon Greases and Waxes exhibit low compressibility, good flow characteristics, and broad materials compatibility. Combined with their nonreactive and nonflammable properties, these products provide a safe and tight seal that does not crack or cure, making them superior to alternatives like PTFE tape or anaerobic sealants.
Engineered greases for reliable thread sealing
InfinX MRO 2510 is the first commercially available monolithic grease, formulated from PCTFE oil and PCTFE polymer thickener. The unified chemistry ensures strong molecular cohesion between thickener and oil, maintaining consistent lubrication and preventing base oil and thickener separation under temperature cycling. While PFPE greases offer similar thermal stability and chemical inertness, the chemical differences between PFPE base oil and PTFE thickener result in weaker interactions that can cause oil separation, leading to stiffness and reduced performance under rapid temperature changes. InfinX MRO 2510 offers improved stability and reliability in the most demanding environments – guaranteeing seizure free assembly and disassembly.
InfinX MRO MT-3i is a molybdenum containing PCTFE grease formulated with PTFE thickener and a proprietary rust inhibitor. MT-3i forms a protective boundary layer between metal-to-metal contacts under high loads and pressure – preventing galling, seizure, contact welding, and mechanical damage in threaded connections. MT-3i properly fills surface asperities promoting smooth assembly and disassembly, satisfying long term MRO demands.

Halocarbon Greases outperform traditional options when safety, chemical resistance, and non-curing functionality are mission-critical — especially in oxygen service, reactive systems, or precision assemblies – making these lubricants a trusted choice across the aerospace, chemical manufacturing and high-purity gas industries. Unlike PTFE take and anaerobic sealants, which may lack effective lubrication or mechanical gap filling, Halocarbon greases provide adhesive-like sealing combined with superior lubrication and protection in demanding environments.
Why choose Halocarbon for thread protection?
Halocarbon anti-galling greases are trusted across aerospace, energy, and chemical processing industries for their ability to perform under pressure—literally and chemically. These greases stand up to aggressive materials like halogens and acids without breaking down, making them ideal for critical sealing points in demanding systems.
They’re also nonflammable and nontoxic, providing added safety in high-risk environments. Thanks to broad material compatibility, they won’t degrade metals, plastics, or elastomers over time. And with dependable performance across a wide temperature range, they help ensure tight, trouble-free connections even under extreme thermal and mechanical stress.
