What Is JetLube White Lithium Grease with PTFE and Who Is It For?
JetLube White Lithium Grease with PTFE is a premium, all-purpose NLGI Grade 2 grease formulated for superior performance and protection of metal and moving parts across virtually any use environment. It is built on a lithium 12-hydroxy thickener with a petroleum oil base fluid, giving it a consistent white appearance and a density of 7.80 lbs/gal (specific gravity 0.95).
The grease is designed for professionals and facilities that need a single lubricant capable of handling plant machinery, marine hardware, automotive components, and residential equipment without switching products. JetLube positions it as the preferred choice for metal-to-metal lubrication in the plant, shop, home, auto, and boat environments.
It carries NSF Registration #137549 and meets NSF (H-2) and 1998 USDA (H-2) guidelines for use in federally inspected meat and poultry plants in noncontact areas. It is also authorized for use by Agriculture Canada. The grease is available in a convenient aerosol package — contact sales@jetlube.com for package types and part numbers.
How Does the PTFE Additive Package Protect Against Wear and Corrosion?
The additive system in JetLube White Lithium Grease with PTFE combines organic extreme-pressure (E/P), anti-wear (A/W), rust-and-oxidation (R&O), and PTFE additives. This multi-functional package is what separates it from a basic lithium grease — each additive type addresses a distinct failure mode.
- E/P additives protect metal surfaces under heavy loads, confirmed by a 4-Ball Weld Point of 200 kgf (ASTM D-2596) and a Load Wear Index of 25.
- Anti-wear (A/W) additives limit surface damage under sliding contact; the 4-Ball Wear Scar Diameter is 0.7 mm (ASTM D-2266).
- PTFE forms a durable dry-film layer that reduces friction and eliminates squeaks and squeals in metal-to-metal contact zones.
- R&O additives prevent rust and corrosion, validated by a Copper Strip Corrosion rating of 1A (ASTM D-4048) — the lowest possible corrosion level on that scale.
Oxidation resistance is confirmed at less than 5 PSI drop over 100 hours (ASTM D-942), indicating the grease resists chemical degradation during extended service intervals.
What Temperature Range Does JetLube White Lithium Grease with PTFE Cover?
The service rating runs from 0°F (−18°C) to 370°F (190°C), making it suitable for cold-start conditions as well as sustained high-temperature applications such as fan motors, electric antenna mechanisms, and industrial machinery operating near heat sources.
The dropping point is 390°F (199°C) per ASTM D-566, which is the temperature at which the grease structure collapses and the oil separates. The gap between the upper service limit (370°F) and the dropping point (390°F) provides a narrow but real safety margin — do not apply this grease in continuous duty above the rated service temperature.
Flash point exceeds 430°F (221°C) per ASTM D-92 (bulk), and the calculated autoignition point is above 500°F (260°C), confirming safe use around typical industrial heat sources without fire risk under normal operating conditions.
Base oil viscosity is 100–160 cSt at 40°C (ASTM D-445), placing it in the medium-viscosity range appropriate for moderate-to-high speed rotating equipment and sliding mechanisms.
Where Should You Apply JetLube White Lithium Grease with PTFE?
The product is formulated as a general-purpose lubricant across four primary sectors:
- Industrial: machinery, tools, overhead garage door channels, fan motors, slides, gears
- Marine: cables, couplings, gears, hitches, winches
- Automotive: hinges, electric antennas, latches, springs, coils
- Residential: implements, door channels, slides, locks
The NSF H-2 registration extends its use to food-service environments — specifically all areas where food contact cannot occur. It is not rated for incidental food contact (H-1); verify the H-2 designation is acceptable before deploying in food processing facilities.
The grease’s high adhesion and resistance to water washout make it particularly effective in marine and outdoor applications where conventional greases would be diluted or displaced by moisture. Its NLGI 2 penetration range of 265–295 (ASTM D-217 at 77°F) confirms the standard worked consistency expected for grease gun, cartridge, and aerosol application to standard fittings and open surfaces.
How Does JetLube White Lithium Grease with PTFE Compare to Standard Lithium Grease?
A standard NLGI 2 lithium grease without PTFE or an organic E/P package will carry a lower weld point and higher wear scar diameter under the same 4-Ball test conditions. JetLube’s 200 kgf weld point and 0.7 mm wear scar reflect the combined benefit of PTFE dry-film lubrication layered on top of the E/P and A/W chemistry.
Without PTFE, squeaking in metal sliding contacts — door channels, antenna mechanisms, latches — typically persists even with adequate lubricant film because boundary conditions allow metal-to-metal micro-contact. PTFE fills those micro-gaps, which is why the product specification explicitly calls out elimination of squeaks and squeals as a design outcome rather than a generic marketing claim.
The oxidation resistance figure of less than 5 PSI drop at 100 hours (ASTM D-942) also demonstrates meaningful R&O additive performance — a baseline lithium grease without R&O treatment would typically show a higher pressure drop indicating faster oxidative degradation.
Summary
- JetLube White Lithium Grease with PTFE is an NLGI 2 grease rated for service from 0°F (−18°C) to 370°F (190°C) with a dropping point of 390°F (ASTM D-566).
- The additive package combines organic E/P, A/W, R&O, and PTFE; the 4-Ball Weld Point is 200 kgf and wear scar diameter is 0.7 mm.
- Copper Strip Corrosion is rated 1A (ASTM D-4048) and oxidation resistance is less than 5 PSI drop over 100 hours (ASTM D-942).
- NSF Registration #137549 qualifies it for H-2 noncontact use in federally inspected meat and poultry plants; Agriculture Canada authorization is also confirmed.
- Applications span industrial machinery, marine hardware, automotive hinges and antennas, residential locks, and food-service noncontact areas.
