DX Engineering Penetrox

This one is a thick paste/putty - guys relocate it to a wide tin and use toothpicks to apply:

• Ensure a proper electrical connection between aluminum and copper metal parts such as conductors, telescoping aluminum tubing, or other antenna and grounding parts
• Intended to be used between all aluminum to aluminum and aluminum to copper tubing or bare conductor connections.
• Compounds of a natural oil base with suspended zinc particles, which ensure high conductivity at all voltage levels by displacing moisture and preventing the corrosion or oxidation of the metal.
• Not recommended for use with rubber or polyethylene insulated wire

Most common for us:

• No-Ox ID - Anti-corrosive for conductors in dirty environments
• Dry-film silicone - For lubricating plastic parts
• Denatured alcohol - For cleaning insulating components
• Industrial degreaser - For cleaning metallic components
• Silicone dielectric grease - For an environmental seal on insulating components
• Mobilegrease 28 - Lubricant for high-force applications and anti-oxidant in clean environments
• Silicone spray - For lubricating moving low-tolerance moving metal

As a rule of thumb we try to stay away from lithium and graphite, because they can have very unforgiving compatibility issues and which will actually be much worse than no lubricant at all.

For intensive cleaning of heavily contaminated equipment, believe it or not the best thing I've seen is tap water and Simple Green. Works like an absolute champ, but afterwards you need extensive rinsing, drying, and testing.

Sanchem No-Ox ID A-Special (Chicago IL)

Thank you Big John, ohmontherange, for suggesting the No-Ox ID.
It looks like the least toxic anti corrosive agent I've seen yet:

No-Ox ID is NSF approved for drinking water tanks and USDA approved as a lubricant/rust proofing compound for meat & poultry plants

No-Ox ID A-Special has specific applications listed on their website:

• Apply a thin coat of this electrically conductive grease to mini-lamp bases before inserting into sockets.
• Apply to base of lamp socket and lens contact area.
• Apply to all electrical conduit connections by packing the end of the tubing and nut before connecting to box connection.
• Apply to all wire terminal connections and wire splice connections. Dip the spade or ring into the NO-OX-ID
• Apply to all electrical junction box connections or terminal posts in light system, starter cable connections, alternator terminal connections, battery posts connectors and ground connections.
• Apply a thin coat of this electrically conductive lubricant to 7-way trailer plug connections and VW cable connector.
• Use NO-OX-ID A-Special as a battery terminal grease to prevent battery corrosion for your car battery maintanance and marine battery maintanance. For battery connections coat the post, screw, clamp, terminal liberally with NO-OX-ID.

SPECIFIC ALUMINUM CABLE APPLICATION
When splicing aluminum cable with compression-type connectors, brush NO-OX-ID A-Special to the inside surfaces of the connector. Using a wire brush, brush these inside surfaces through the through the A-Special coating. This roughs up the surface assuring positive contact. At the same time the NO-OX-ID A-Special is providing protection against the oxide film, that can occur in the short space of time between roughing up the surface and final connection. Apply a thin coat of NO-OX-ID A-Special to cable ends to complete the splice to prevent aluminum rust.

Fallacy of adding metals to increase Conductivity:
Many contact greases have copper, zinc or other metals blended into a grease to increase conductivity. In a study for an aerospace company in 1985 it was concluded that putting a metal into grease does not help conductivity. In many cases it reduces conductivity. The United States Department of the Interior Bureau of Reclamation in their Facilities instruction Journal Volume 3-3 Electrical Connections for power circuits states in Sec. 6.3.2 that "Use of grease with embedded zinc particles will cause a poorer connection due to the lower conductivity of zinc".

Aluminum Oxide is one of the hardest substances known to man, just softer than diamonds. How can a metal as soft as Zinc cut through it? It can't! Zinc metal can not dissolve aluminum oxide either. The aluminum oxide that typically forms on an aluminum connection is only 50-120 angstroms thick. Sanchem's NO-OX-ID penetrates the oxide film by the chemical action of our corrosion inhibitor system.

Who sells this stuff?

 

[markore]

You can try google, I don't want to get in trouble with the mods for posting sales links. This area is mainly just for discussion of the performance of the different brands of compounds and chemicals, not so much on pricing and availability. I can tell you a major retailer is listing it as Ham Radio Conductive Grease.

 

[Spunk#7]

I found it 2oz. $12.70 plus shipping. I was looking for a cheaper source No -ox has gone through the roof lately. Somebody need to make something that isn't so messy,you know like a nice liquid you dip the wire in or brush on.

Honestly, that's why we use Mobile 28.

It's not designed as an electrical antioxidant, but I've seen it in enough OEM literature, and I've done enough testing where it's been applied, that I'm really comfortable that it will safely seal out the environment on dry electrical connections.

It's thinner and much less tacky than No-Ox, and it sells for less than $1-per-oz.

 

[Spunk#7]

Could you tell we aviation impaireds what Mobile 28 is? I did a quick search,found it for sale(reasonable). Is it considered a lubricant? Does it have aluminum oxidation inhibiting abilities? Anything has to be better than what available at supply houses.

 

[Big John]

It's a really good high-strength grease that we use on mechanical pivots and slides.

But if you read through a lot manuals for large circuit-breaker, they say to use a thin film of it on the stabs or fingers where the breaker connects to the bus.

I figure if it's good enough for the electrical connections of a 4000 amp circuit breaker, it's good enough for other stuff. We use it as a general-purpose anti-oxidant and it works great.

Actually makes me wonder if in reality, practically any inert grease would work just as well as No-Alox...?

Interesting, thanks for posting that.

I Googled it and this was the first hit.

Mobilgrease 28
Synthetic Aviation Grease
Product Description

Mobilgrease 28 is a supreme performance, wide-temperature, antiwear grease designed to combine the unique features of a polyalphaolefin (PAO) synthetic base fluid with an organo-clay (non-soap) thickener. Its consistency is between an NLGI No. 1 and No. 2 grease. It offers outstanding performance over a wide temperature range. The wax-free nature of the synthetic base fluid, together with its high viscosity index compared to mineral oils, provide excellent low temperature pumpability, very low starting and running torque, and can help reduce operating temperatures in the load zone of rolling element bearings.

Boy they can talk up grease. Pumpability. :laughing:

There must be some touted benefits, it does seem to adhere better than normal grease.

You mentioned simple green cleaner, will that clean up real No-alox? I kind of doubt it would but I don't know.

 

[Spunk#7]

I found cleaning up No-alox type inhibitors off the truck seats,my clothes,the furniture, is pretty easy with waterless hand cleaner and a brush. After all these years it's just a world class pain in the Butt! Plus it's gotten expensive!

Well, most advocate using electrical specialty grease for these 4 specific purposes:

• Seal out oxygen / water vapor (Gas tight joint)
• Seal out liquids (which catalyze corrosion / galvanic reactions)
• Lubricate insulators like rubber spark plug boots
• Reduce galling/seizing

Many types of grease used in electrical applications are nonconductive insulators and are designed for use in high pressure contacts that displace the grease from between conductors.
