Jet-Lube anti-seize compounds (also written Jetlube, Jet Lube or antiseize) are not interchangeable. The base metal, the service temperature, the nut factor and the approvals decide which one belongs on a given bolt. This page compares 12 Jet-Lube anti-seize compounds listed on pe-energy.com, using only the figures Jet-Lube prints in its own Technical Data Sheets (each one linked below), so a maintenance planner can pick the right grade before ordering.
Which Jet-Lube anti-seize should I use? The comparison table
Read the table by the job first: temperature, the metals involved, and any approval the site requires. Every figure below is copied from the linked Jet-Lube Technical Data Sheet. Nut factors are measured under different test conditions on different sheets, so compare them within the same condition only.

What does a Jet-Lube anti-seize actually do on a bolt?
An anti-seize keeps threaded and press-fit parts from galling, seizing and corroding, so they come apart without damage at the next shutdown. It also makes tightening predictable: the nut factor K links torque to bolt tension in the short-form equation T = K × D × F that the sheets use, so for the same bolt and clamp load, a lower K needs less torque.
From the data sheets: on these 12 sheets the printed nut factors run from 0.13 (SS-30 Extreme, Graphite Petrolatum) to 0.19 (550 Extreme at 30 ksi), each under its own test condition. The two Extreme sheets show how the factor moves with contact stress on the same 1″ uncoated B7 stud: 550 Extreme goes from 0.15 at 80 ksi to 0.19 at 30 ksi, and 550 Extreme All Weather from 0.16 to 0.18, which is why a torque table should name both the compound and the contact stress it was built for. Kopr-Kote’s sheet states it “permits reuse of fittings” and saves stud, bolt and nut replacement.
Which Jet-Lube anti-seize handles the highest temperature?
Of the 12 compounds on this page, three carry the highest service rating, -65°F to 2600°F (1427°C): Nikal, Nikal Nuclear and Marine Grade. The 550 family follows at 2400°F (1316°C) (for the two Extreme grades, in select services), then Kopr-Kote, SS-30 Extreme, White Knight and Silver Plus Regular at 1800°F (982°C). The two petrolatum compounds have the lowest ceilings, 900°F (482°C) for Graphite Petrolatum and 800°F (427°C) for Moly Petrolatum.
From the data sheets: the sheets flag which ingredients matter at high temperature. The Nikal sheet notes it contains no graphite, “a benefit on stainless steel applications when temperatures exceed 550°F,” because graphite can carburize the steel. The Moly Petrolatum sheet warns that its MoS2 at 1000°F and above may induce corrosion of the fastener or contiguous materials, and points high temperature work to a product it calls NUCLEAR NONMETALLIC, which is not one of the 12 compounds compared here. The 550 sheets, which also contain MoS2, carry their own 2400°F rating.
550 vs 550 Extreme vs 550 Extreme All Weather: what is the difference?
All three are nonmetallic Jet-Lube 550 anti-seize and thread lubricants rated to 2400°F (1316°C). Plain 550 is the general maintenance grade. The two Extreme grades use a calcium sulfonate complex base, and both sheets call them ideal for petrochemical plant maintenance; the 550 sheet itself says “For Delta valves and coker units use 550 EXTREME or 550 EXTREME ALL WEATHER GRADE.”
From the data sheets, side by side:
- Weld point and salt fog: 550 lists 620 kgf and +200 hrs; both Extreme grades list 800 kgf and 500 hrs.
- Nut factor at 80 ksi on 1″ B7 studs: 550 at 0.17, 550 Extreme at 0.15, 550 Extreme All Weather at 0.16.
- Cold weather: 550 Extreme is brushable to -10°F (-23°C); 550 Extreme All Weather is brushable to -50°F (-46°C) in its service table (its feature list says -40°F).
- Valve and coated bolting: of the three 550 sheets, only the 550 Extreme sheet carries the Low “E” claim (better conformance to API 622 Low “E” criteria when used with graphite stem packings), the Raytheon M8656839 Type III conformance, and improved torque repeatability on XYLAN and DOXSTEEL coated bolting.
None of the three data sheets compares the two Extreme grades directly, so the points above are read across the three sheets.
Copper, nickel, aluminum or nonmetallic: which base do I need?
The base sets where the compound is safe. Copper grades (Kopr-Kote, SS-30 Extreme) are listed for threaded connections, studs, bolts and flanges, and SS-30 Extreme for subsea nuts and bolts. Nickel grades (Nikal, Nikal Nuclear) go where copper is a problem or heat is extreme. Nonmetallic grades (the 550 family, Marine Grade, White Knight) carry no metal flake: the 550 family relies on MoS2 and graphite, Marine Grade is nonconductive, and White Knight’s sheet states it contains no metals. Silver Plus Regular uses aluminum.
From the data sheets: Nikal “may be safely used with ammonia, acetylene and vinyl monomers, which are unstable in the presence of copper.” Marine Grade is nonconductive, and its sheet says its boundary lubricants were selected “to reduce the potential for galvanic corrosion” and to protect galling prone alloys such as chrome and Inconel. Silver Plus Regular, because its primary particles are aluminum, “nearly eliminates the potential for galvanic corrosion,” while Graphite Petrolatum carries the opposite warning: graphite may promote corrosion of aluminum, ferrous, magnesium, zinc or cadmium alloys or plated surfaces, and the sheet says not to use it in contact with these metals where galvanic corrosion conditions exist.
Which Jet-Lube anti-seize is food grade?
Of the 12 compounds here, White Knight is the food grade Jet-Lube anti-seize: NSF H1 registered (Reg. #048235) for incidental food contact and conforming to FDA 21 CFR 178.3570. Kopr-Kote Anti-Seize is not a food contact grade: it is NSF registered in category H2 (No. 120923), the NSF category for lubricants used in food plants only where there is no possibility of contact with food. The aerosol package is not NSF registered.
From the data sheet: White Knight is “developed specifically for use in applications where incidental food contact is possible,” contains no metals, and is listed as non-staining, odorless and tasteless, with bottling machinery, packaging machinery and conveyor and oven bearings among its applications.
Which Jet-Lube anti-seize is made for marine, offshore and subsea work?
Of the 12 here, Marine Grade Anti-Seize is the environmental grade: it meets the requirements for an environmentally acceptable lubricant (EAL), is OSPAR compliant, and is registered by CEFAS in the UK and KPD/SFT in Norway. SS-30 Extreme is the sheen free copper grade formulated for subsea fittings.
From the data sheets: Marine Grade reports salt fog resistance of more than 2000 hours in 5% NaCl and more than 750 hours in 20% NaCl, and falls within the environmentally preferable lubricants used as a best management practice under the Vessel General Permit. SS-30 Extreme states it contains no lead, zinc, molybdenum disulfide or graphite.
Where should a Jet-Lube anti-seize not be used?
Six of the 12 sheets rule out oxygen service: 550, SS-30 Extreme, Nikal and Nikal Nuclear are marked not for use on oxygen lines, White Knight not for use on oxygen services, and Silver Plus Regular’s petroleum carrier makes it unsuitable for oxygen service. The other six sheets do not mention oxygen at all, so none of the 12 compounds on this page is rated for oxygen service. On spark plugs, Graphite Petrolatum goes on the threads only and must not touch the terminals or electrodes; the sheet notes it is an electrical conductor.
Before ordering: check the site’s approved product list against the approvals column above. Of the 12 here, Nikal Nuclear is the grade written for nuclear plants where only certified products are allowed and ships with a Certificate of Conformance; White Knight is the H1 registered grade for points where incidental food contact is possible; Marine Grade carries the CEFAS and KPD/SFT registrations an offshore operator may ask for.
