## Overview

ProSeal 80726 High Temperature RTV Silicone Instant Gasket is a red, fast-curing sealant designed for high-heat automotive and industrial applications. It forms leak-proof, flexible gaskets that resist extreme temperatures (-56°C to 315°C continuous, up to 343°C intermittent), high pressures (up to 5000 psi), and harsh chemicals like oils and antifreeze. Safe for all car models and sensor-friendly, it ensures reliable, durable sealing for metal, rubber, and high-temp surfaces.

## Description

Red Hi-Temp RTV is specially formulated for high temperature applications. Withstands temperatures from -56ºC up to 315ºC (-70ºF up to 600ºF) continuous and up to 343ºC (650ºF) intermittent. Safe for all car models. Will not foul computer sensors. Resists high pressures to 5,000 psi. Resists oil, antifreeze, grease and transmission fluids. Dries flexible. Resists shrinking and cracking.

Review: Works well but tends to dry out like most sealers do so I suck and seal it when I'm done using it to help it last. Sealed the wheel bearing housing on my JD three series tractor. There was a little oil dripping out when I mated the parts together so I thought there might be a sealing problem but it's fine after a few months of use. Highly recommended.
Review: This is a really good sealant and easy to dispense from the tube with the nozzle provided. I used it on an oil sump pan with no leaks after leaving for the specified 24 hours to cure.

## Questions & Answers

**Q: Can you use it for a temp guage on a grill? i.e. Is it food safe?**
A: This product does not indicate that it is food-safe however may be suitable if not in contact with any food. Excellent in high-temp applications and can often be used as a glue also, on clean surfaces. Hope this helps.

**Q: Can I use it for making gasket for oil pan?**
A: You can use for gasket making but it's not the best. Use the black rtv

**Q: Will it stick to acoustic foam?**
A: Yes

**Q: How long does it take to dry?**
A: I left it overnight and it was dry in the morning. Worked great.  If I still had it I’d read the label and tell you what it says the drying time is, but I no longer have the tube.

*by A***N on 18 January 2019*

Parfait pour créer des "chaussettes" de buses d'imprimantes 3D : je fabrique un moule à m'imprimante 3D, que je remplis de ce silicone, qui permet ensuite d'habiller mes buses pour limiter les déperditions de chaleur. J'en suis très content !
