## Overview

Shin-Etsu Hivac-g is a 3.5 oz high vacuum silicone grease engineered for superior sealing in demanding dielectric and vacuum applications. It offers exceptional heat resistance, chemical stability, and oxidation durability, maintaining vacuum levels as low as 10⁻⁶ mmHg. Its refined low-viscosity formula ensures smooth application on precision joints and seals, making it a trusted choice for professionals in scientific, automotive, and industrial fields.

## Description

The hivac-g features a specially refined silicone fluid of base oils, with silica powder worsen. This oil compound, excellent heat resistance, oxidation stability and chemical stability. Through a refined, hair concentration process achieves low levels of volatile content and results of 10-6 mmHg high vacuum degrees. The extremely tight seal gasket and sliding mechanism on hivac-g foam are widely used as a sealant and compatible with high vacuum devices.

Review: 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.
Review: 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.

*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..
