D A M Exhaust Lube
FAQs for "D A M Exhaust Lube"
Frequently Asked Questions
All other anti-seize I have used are thick. How can this work when it is so thin?
The D A M high temperature anti-seize formula is based on inert high temperature dry lubricants suspended in a naptha carrier with a few other low viscosity additives. The thick grease base in other anti-seize products on the market burn and char at exhaust temperatures leaving sticky hard deposits that actually contribute to the lock-up of exhaust joints. The D A M product carrier evaporates leaving only a film of dry lubricants in the joints that penetrates the pores of the stainless steel.
How does the D A M product work to loosen locked slip joints?
D A M’s light petroleum carrier uses capillary action to penetrate the joint and carry the small particles of dry lubricant into the joint. By mixing D A M and other solvents such as acetone, MEK or other solvents the viscosity is lowered more yet and the mixture will penetrate small spaces more effectively to loosen corrosion and combustion by products while lubricating the joint.
How is the D A M product different than other anti-seize products?
D A M anti-seize works on the principle of very small particles of inert dry lubricants imbedding themselves into the open pores of the stainless steel. The dry lubricants lowers friction and prevent corrosive adhesion of the two stainless steel surfaces. The dry lubricants prevent combustion by products from actually gripping the stainless steel. Other products rely on powdered metal such as copper or nickel in a mix of greases and graphite. The powdered metals themselves are often corrosive to the stainless steel at high temperatures and actually create adhesion by microscopic corrosive residue. The old failed theory is that the metal powder flakes will separate from each other and allow disassembly. This does not work at high temperatures and with stainless steel. Any graphite in the compound (graphite is required for MIL SPEC anti-seize compounds) sets up a severe galvanic corrosion action with the stainless steel and the powdered metals that produces corrosive by products that swell and lock the joint while attacking the grain structure of the stainless steel. This corrosive action is accelerated at high temperatures and contact with combustion by products.
Is there anything I can do to make D A M work better?
Since D A M is a mixture of heavy dry lubricants and light petroleum distillates, it will separate quickly. Shaking the can often during use keeps the lubricants in suspension. D A M works best when it is rubbed into the stainless steel. Rotation joints back and forth before final assembly will help imbed the dry lubricant particles into the stainless steel surface. Then disassemble and recoat the joint.
It is in a small can. Will it do very many exhaust joints?
Only a thin film is required to be on the surface of both parts of the exhaust joint so the small can will service many more exhaust joints compared to a big can of pasty grease.
Why does a small can of the D A M product cost so much?
The high temperature inert dry lubricants are expensive to produce and refine. Since it only takes a thin film to be effective it is more economical than other anti-seize compounds. A can goes much further.
Aircraft Exhaust Anti-seize/Lubricant — The only anti-seize that works!
D A M Exhaust Lube is designed specifically for aircraft exhaust ball joints, clamps, slip joints, and hardware. A low viscosity liquid is blended with molybdenum-disulfide and other special micro-lubricants to produce a protective dry lubricant film. This film imbeds into the stainless steel and keeps your joints lubricated for years!
- Protects up to 2400° F
- No stainless corroding graphite
- Prevents heat corrosion and joint lockup
- Joints stay free to move with thermal expansion
- No greasy powdered metal paste that locks up anyway
- Low viscosity — a little goes a long way
- Loosens assembled joints
Note: Do not use an anti-seize that contains graphite on your exhaust systems. Graphite corrodes and destroys the grain structure of stainless steel. D A M™ Exhaust Lube does not contain graphite.
