In stock and ready to ship. But we need to understand what it is to begin with, in order to properly apply it in the field. So, it is an insulator. And must assure that it must not touch where you are connecting the components or in the path of the electric current. This issue here is the same for any use of lubricants/grease no matter what the application or who the lubricant manufacturer is; some oils/grease can make plastics and/or rubbers swell, crack or cause discolouration. A thin film of lubricant can also reduce mating force by as much as 80 percent, an important factor in connector assembly. It lubricates, reduces contact resistance, repels moisture, inhibits corrosion, and prevents static buildup. Uniflor 8917 possesses excellent thermo-oxidative stability and is ideal for hazardous environments and extreme temperatures. Over the years we have noticed manufacturers using gold plated contacts to deal with the threat of fretting corrosion but OEMs can end up dealing with dealing with fretting despite using gold as enough of the gold coating is scratched away during initial mating, negating the use of gold in the first place….especially where the thickness of the gold plating is really probably too thin in the first place. Where Should You Not Use Dielectric Grease? So, use the dielectric properly with an electrical connection. A note about the general chemistry of the connector greases available….If you are unfamiliar with connector grease/lubricants, these are not ‘grease’ in the typical sense, if you have only really used cheap grease in the past, i.e. Can Vaseline be used as Dielectric Grease? (Supervisory Control and Data Acquisition), Programmable Logic Controllers (PLCs): Basics, Types & Applications, Diode: Definition, Symbol, and Types of Diodes, Thermistor: Definition, Uses & How They Work, Half Wave Rectifier Circuit Diagram & Working Principle, Lenz’s Law of Electromagnetic Induction: Definition & Formula. Moisture buildup on plugs and sockets can corrode their contacts. So let’s summarise the main reasons for choosing an electrical/electronic connector lubricant, which will mostly be one or more of the following reasons: There are four core products from the connector grease range, manufactured by our partners at Nye Lubricants. Blend of Polyalphaolefin (PAO) and Alkylated Naphthalene (AN) base oil, Urea thickened. The dielectric grease is a translucent substance that mainly used to protect and seal electrical circuits and widely used motor industries, electrical circuits, and automobile applications. Inflate the dielectric grease on one probe of the multimeter. Rarely any compatibility issues with plastics or rubbers as the base oil used in the formula is inert. Therefore, it is used in the marine application and outdoor application to make electrical components waterproof. Dielectric grease comes in handy to protect the rubber and plastic parts of the connectors too. Full disclaimer here. Because it is non-conductive, it does not allow the flow of electrical current. Dielectric grease, or tune-up grease, is a silicone-based grease that repels moisture and protects electrical connections against corrosion. For gold-plated connectors, an effective lubricant, like our industry standard NyoGel® 760G reduces the potential for noble metal wear during mating and separation. A lubricant film minimises metal to metal contact during vibration, protecting the connector from metal wear. With gold-plated connectors this means protection against substrate corrosion. Corroded parts may no longer make a good connection. synthetic grease for fixed or mobile connections also exposed to harsh environmental conditions or subjet to vibration.-40 +135. There is a myth floating around that putting dielectric grease into electrical connections can cause them to fail because the grease gets between the metal. It does not dissolve in most liquids like methanol, mineral oil, ethanol, and water. Electrical Contact Grease comes in a 2 oz. It's commonly used in automotive spark plug wires, recreational and utility vehicles, and electrical systems in aircraft. Compatible with most plastics and elastomers/rubbers. Dielectric grease is an insulator. Why use an ultrafiltered lubricant in a cleanroom or vacuum environment? It is silicone based, which makes it an effective barrier against moisture and salt precipitate. Dielectric grease is an insulator. It combines Recommended temperature range of -40 to 175°C. If the connector consists of more than just one contact/pin (e.g. Guaranteed Lowest Price and Fastest Shipping for Dielectric Grease for Electrical Connectors, 2 oz.. Corrosion is caused by moisture coming into contact with the metal parts of anything electric. The cost of dielectric grease is very high compared to the Vaseline. Hence, when you use the dielectric grease, keep the grease away from the path of electric current. Because it is non-conductive, it does not allow the flow of electrical current. Rheolube 748S: synthetic grease for contacts with the presence of arc; leaves no carbon residue in the case of arc. Dielectric Grease/Silicone Paste/Waterproof Marine Grease (8 Oz.) The process of fretting corrosion causes micro abrasion of the contact surfaces and continually exposes fresh layers of the metal surface to oxidation. Hence, it prevents the flow of current. Discussion in 'The Garage' started by makar, Sep 10, 2020. One of the popular dielectric greases to use is Permatex Dielectric Grease and CRC dielectric grease. Readers of this article should not be alarmed but due care should be taken so we recommend you read our article on Lubricant and Plastic Compatibility Issues. Hence, when you use the dielectric grease, keep the grease away from the path of electric current. The Vaseline is also known as petroleum jelly that also used in the industries to avoid corrosion and finishing woods. They are clamped tightly together. Amazon's Choice for conductive grease for electrical connections. Nyogel 760G is compatible with all metals including gold and silver. A guard against corrosion – Lubricants guard against oxidation and the effects of harsh environments. Neither is true. More products are available and where relevant Nye will custom formulate a product for your requirements. $21.95 $ 21. NyoGel® 760G - The Leading Connector Grease.
