## Overview

ShinEtsu's HIVAC-G High Vacuum Sealing Compound is a premium silicone grease designed for dielectric and sealing applications. With exceptional oxidation resistance, chemical stability, and thermal resilience, this compound is perfect for high vacuum environments, making it an essential tool for industrial and mechanical professionals.

## Description

HIVAC-G features a base oil of specially refined silicone fluid, compounded with silica powder. This oil compound has excellent heat resistance, oxidative stability and chemical stability. Through an intensive refining process, volatile content has been reduced to very low levels, thereby making it possible to attain high vacuums of 10-6 Torr. HIVAC-G forms exceptionally tight seals on gaskets and sliding mechanisms, and is widely used as a sealing compound for high vacuum devices.

Review: Quality is good. Works as intended for car door seals - Bought for husband who takes care of the vehicles. He likes the product and used around front door seals. Wind noise was reduced after use so it helps.
Review: Good product, great price, a little "thin" but works great - I needed a grease for ground glass taper joints and glass syringes. This product is thin, less viscous / stiff than Vaseline. For joints with tight tolerances or valves this worked well. For dessicator jars I am thinking I want something a bit stiffer. It definitely has a great price point, which is why I'm giving it a 5/5. As a release coat for casting epoxy it worked well. And I think for sealing vacuum chambers / bell jars which are under compression it will be great.

### ⭐⭐⭐⭐⭐ Lexus seals look almost new.
*by C***. on December 15, 2025*

Used this on my 2006 Lexus LS 430's sunroof seal and the exterior door seals. While applying it, I could see it disappearing into the seals, literally drinking it in. I've applied it three times in the last week as the seals were SO...dry. Now? WOW...they all look almost new. They are actually pliable now, and feel and look so...much better. Excellent product, a little dab goes a long way, so inexpensive to use. Highly recommended..
