Dielectric grease sprayer 16 oz

This 16 oz aerosol delivers a silicone-based dielectric paste that improves electrical performance in rain, fog, salt spray and temperature extremes. It lubricates rubber and plastic parts while resisting weather and water. The translucent NLGI Grade 2 compound suits automotive and marine connections.

For electrical maintenance and assembly

Technicians protecting connectors, battery terminals or spark-plug boots from moisture and corrosion will find it effective. It also eases assembly of rubber grommets and plastic housings. Buyers who need a conductive paste or a high-temperature thread compound should look at something else.

16 oz capacity for repeated jobs

The can contains enough paste for many connector coats and lubrication tasks across a workshop or fleet. Operating range spans -70.0 F to 400.0 F, so it stays functional in severe cold and engine-bay heat. Very large-scale industrial programmes may require bulk packaging instead.

Questions about this item

What electrical connectors or rubber and plastic parts should already be in place before applying this 16 oz dielectric grease?

Apply it to battery terminals, spark plug boots, trailer connectors, bulb sockets or any rubber and plastic components that need moisture protection and lubrication.

Will the -70.0 F to 400.0 F temperature range protect the grease on older wiring harnesses that see engine heat and winter cold?

Yes, the range covers extreme cold and high under-hood heat, so the grease stays pliable and does not melt or harden on aged harnesses.

How can I confirm the spray is dispensing the translucent NLGI Grade 2 paste correctly after setup?

Shake the aerosol can, spray a short burst and check that a translucent, paste-like film coats the test surface evenly.
