Know the Never-Seez® Product Options
Reduce friction and error likelihood: Never-Seez® compounds help you disassemble machinery, piping and metal parts without destruction and decrease the potential for thread distortion, exposure effects and galvanic corrosion that can result in galling and seizure.
Increase efficiencies: Never-Seez® compounds decrease downtime and production costs with their spreadability, providing up to 6,480 in2 coverage per lb. based on 4 mil. film thickness.*
*Based on internal testing
Increase protection: Never-Seez® compounds seal metal components under extreme heat and pressure, providing long-term protection against corrosion, galling, seizing and pitting after exposure to various environmental factors such as temperatures, chemicals
or moisture.
Never-Seez® Regular Grade offers a wide range of protection against corrosion, rusting, pitting, seizure and galling, which is why it serves as our most popular MRO maintenance solution. However, there are situations where a specialized option should be considered instead. Click on each Never-Seez® product to learn when to consider a specialized grade.

Never-Seez® FAQ
How do I clean-up or remove Never-Seez®?
Using a cloth or paper towel can help wipe out or remove the majority of Never-Seez®. In order to clean up the residual oil or grease, we recommend solvent paint thinners such as mineral spirits or odorless mineral spirits (OMS), as they are more chemically compatible with the grease carrier or base oil compared to acetone or methyl ethyl ketone (MEK).

How do I apply Never-Seez® for proper torquing?
When Never-Seez® is properly applied, the assembled bolt can be reinstalled. This reduces replacement costs and maintenance downtime, because you don’t need to obtain and install a new one. Read the steps below to learn how to apply Never-Seez® for proper torquing.
Step 1: Apply Never-Seez® to the base of the threads. Ensure full circumference is covered. There is no need to coat the full length of the threads.
Step 2: Screw the nut on the bolt all the way up the shaft. Then, unthread it off to fill in the anti-seize between the bolt and threads. This helps ensure proper coverage for effective lubrication.
Step 3: Apply Never-Seez® under the bolt head before installing.
Pro tip: Be sure to apply Never-Seez® on both the threads and bolt cap. This will allow you to achieve maximum tightening with the least amount of torque.

How do I find the date of manufacture on my Never-Seez® product?
You can find the seven-digit lot number and the six-digit date code printed on the bottom of the Never-Seez® can. Bostik recognizes the item packaged date as Date of Manufacture, i.e., beginning of shelf life. The Date Code is labeled as a year-date-month; for example, a Date Code of 230210 indicates the Date of Manufacture is 02/10/2023. For a production batch made before May 2010 from Bostik Marshall Plant, the lot number and date code are printed on the right bottom corner of the label.
