Small white tube of dielectric grease, 20g

PRAZISCHUTZ Dielectric Grease 20g

SKU CH-QHC8-4SQJ9

Silicone dielectric grease insulates and lubricates electrical contacts while forming a waterproof barrier against corrosion for automotive and marine use

  • Key featuresPrevent Corrosion, Automotive, Marine, Electrical
  • Product weight0.035 kg
  • Product typeGrease
  • Insulates connections while lubricating contacts, preventing short circuits and mechanical wear
  • Safe for switches, plugs and current-carrying components without conducting electricity
  • Waterproof barrier seals out moisture, dust and salt air to stop corrosion
  • Reduces oxidation, arcing and friction to extend electrical part service life
  • Ideal for automotive, marine and outdoor electrical systems exposed to harsh environments

Dielectric Grease for Electrical Connections

Prazischutz dielectric grease is a silicone-based compound that insulates electrical connections while lubricating moving contact points. The 20g tube delivers dual protection against short circuits, current leakage and mechanical wear in a single application. It is formulated specifically for switches, plugs, knobs and other current-carrying components.

Automotive Marine and Outdoor Electrical Maintenance

This grease suits technicians and owners maintaining automotive electrical systems, battery terminals, spark plug boots, marine electronics and outdoor equipment exposed to heat, humidity and salt air. It is not for buyers who need a conductive paste for thermal transfer or a general-purpose mechanical lubricant without insulating properties.

Waterproof Corrosion Barrier in 20g Tube

The hydrophobic barrier seals out moisture, dust and salt air to protect connectors and wiring from rust and oxidation. The .7 oz net weight provides enough material for multiple connector services on a vehicle or boat. Large-scale industrial harness work or continuous production-line use will require a larger container.

Questions about this item

What electrical components do I need on hand to apply this dielectric grease?

Apply it to switches, plugs, knobs, battery terminals, spark plug boots or any current-carrying connectors you are servicing.

Will this grease interfere with the conductivity of my existing battery terminals and spark plug boots?

No — it insulates against short circuits and current leakage while allowing normal electrical flow through the contact surfaces.

How can I confirm the grease is protecting the connections after I apply it?

Look for a continuous hydrophobic film that repels water and prevents oxidation; the treated contacts should stay clean and free of corrosion over time.
