4oz Brush-Top Dielectric Grease

AGS Dielectric Grease comes in a 4oz brush-top can for precise, mess-free application on automotive electrical connectors. The silicone-based compound seals out moisture, prevents corrosion and stops voltage leakage on spark plug boots, battery terminals, wiring harnesses and ignition coils. Made in the USA since 1931, it offers professional-grade protection for DIYers and mechanics alike.

Temperature Range and Application Limits

The grease is formulated to perform from -40°F to +400°F, maintaining its protective seal in extreme automotive environments. It resists washout from rain and road splash while extending the life of connectors and rubber boots. The brush-top lid delivers controlled, targeted application exactly where needed, unlike squeeze tubes that can waste product. This temperature range defines the practical limits for reliable dielectric performance.

4oz Volume for Extended Coverage

At 4oz per can, this product provides 24 times more dielectric grease than competing 1oz tubes at a comparable price point. The larger volume allows users to protect every connector, terminal and spark plug boot in a vehicle without running out mid-job. Buyers who need only a small single-use amount for a one-time repair may find the 4oz capacity more than required.

Questions about this item

Should I choose the 4oz brush-top can or a smaller tube?

The 4oz can gives you 24 times more dielectric grease than typical 1oz tubes, so one container covers every connector, terminal and spark plug boot in the vehicle without running out.

What does the -40°F to +400°F rating mean once the grease is on my connectors?

The silicone compound keeps its protective seal from arctic cold starts through scorching engine compartments, resisting washout from rain and road salt while preventing moisture, corrosion and voltage leakage.

How does the brush-top lid change the way I apply the grease compared with a squeeze tube?

The built-in brush lets you put exactly the right amount on each spark plug boot, battery terminal or wiring harness without the mess and waste common with squeeze tubes.
