TriboSys™ MS-381H | Electrical Connection Lubricant
Six (6) Ring Polyphenyl Ether Lubricant, Prevents Fretting On Sensitive Connectors
TriboSys™ MS-381H Electrical connection lubricant was formed by combining the superior lubricating qualities of Polyphenyl Ether with the cleaning power of a hydrofluoroether azeotrope. Miller-Stephenson has created a nonflammable, Non-ozone-depleting electrical connector lubricant, a formulation that provides the most advanced total treatment for connectors with no interference in electrical continuity.
Electrical Connection Advantages
- Cleans lubricates and protects multi-pin connectors
- Reduces insertion forces
- Greatly increases mating cycles (especially important
where high pin counts are involved)
- Extends connector life by preventing corrosion and
- Removes contaminants and oxides.
- Is non-migrating-contains no silicones
- Available with a UV (ultraviolet) indicator
- NSN 6850-01-519-8521 (MS-381H)
- NSN 6850-01-367-8095 (MS-381H UV)
- RoHS2 and RoHS3 Compliant
VOC content……………………………………….524 g/l
The active ingredient of Connector Lubricant is a six (6) ring polyphenyl ether lubricant. This lubricant will help protect metal connector surfaces from excessive wear, when subjected to hundreds of mating cycles, thereby increasing the life of the connectors. It will also reduce insertion forces and provide corrosion protection in harsh environments. Polyphenyl ethers (PPE) are very viscous fluids and only a very thin film is required. Connector Lubricant MS-381HC/383H is a 2% PPE concentration, which is at the proper concentration for connectors operating at room temperatures where there is little or no vibration. Higher concentrations are available in Bulk formulations.
