Elring Dirko HT high-temperature silicone sealant 70ml red — flexible, heat-resistant to 315°C

Elring Sealant Dirko HT in a 70ml tube is a red, high-temperature silicone sealant designed to form durable, flexible gaskets and seals that resist temperatures from −60°C to 315°C.

This single-quantity 70ml tube of Elring Dirko HT offers a professional-grade silicone compound for engine, exhaust and high-heat sealing tasks. Its red color and wide temperature tolerance make it suitable for hot-engine applications where a resilient, heat-stable seal is required. Lightweight and easy to apply from the compact tube, Dirko HT is compatible with many OEM repair procedures and commonly cross-referenced with several manufacturer part numbers.

How does Elring Dirko HT perform under extreme heat?

Dirko HT is formulated to withstand continuous and intermittent exposure to very high temperatures without hardening or losing elasticity. It stays flexible at low temperatures while resisting decomposition and leak paths at elevated engine or exhaust temperatures.

• Operates between −60°C and 315°C for broad application range
• Silicone base maintains elasticity under thermal cycling
• Resistant to cracking, shrinking, and thermal breakdown

Where should I use this sealant on a vehicle?

The sealant is intended for sealing joints and mating surfaces exposed to heat, such as engine housings, thermostat housings, exhaust components and flange connections. It’s also useful for repairs where a formed, reliable gasket is needed without metal replacement.

• Ideal for engine and exhaust sealing applications
• Can replace or supplement gaskets on housings and flanges
• Suitable for repairs on Mitsubishi, Nissan, Renault, Suzuki, Toyota and other makes (see equivalents)

How do I apply and cure Dirko HT for best results?

Application requires a clean, dry surface; remove old gasket material and oils before use. Apply a continuous bead, assemble parts within the product’s tack-free time, and allow full cure according to manufacturer recommendations for a leak-resistant joint.

• Surface prep: clean, dry, degreased and free of residue
• Apply an even bead from the 70ml tube and join parts promptly
• Allow adequate cure time before exposing to full operating temperature

Is Dirko HT compatible with OEM parts and common aftermarket repairs?

Yes—Dirko HT is frequently specified as a compatible sealing solution for many original equipment and repair procedures. It’s cross-referenced to several manufacturer part numbers and commonly used where a high-temperature silicone gasket is required.

• Equivalent numbers include Mitsubishi MD974421 and Toyota 00295-01281
• Also cross-references Renault, Nissan, Suzuki, Dacia and Hino equivalents
• Single 70ml tube format fits standard application tools and workflows
