Threebond Liquid Gasket Black

When you're elbows-deep under the bonnet or wrangling parts on the job site, you need something you can trust to hold firm when things heat up, literally. That’s where the Threebond Liquid Gasket Black comes in. Designed with sensor safe 320ºC capability and a tack-free time of just 7 minutes, this beast of a gasket sealer laughs in the face of Aotearoa’s rough-and-tumble conditions. Whether you’re a weekend tinkerer or flat-out in the workshop, this is your go-to for no-fuss sealing.

Unlike cheap alternatives that can’t handle the heat, this formula offers superior resistance to high temperatures, keeping things locked tight where it matters, like flanges and surfaces in direct contact with the cylinder head. That means no leaks, no dramas, even when you're giving it heaps on the open road or hauling the boat to the bach. It’s a Kiwi classic: reliable, hard-working, and doesn’t quit when things get tough.

Tradies, mechanics, and backyard battlers alike will appreciate the peace of mind that comes with a proper seal, especially one that’s sensor safe at 320ºC and ready to go tack-free in under 10. And with NZ’s mix of wild weather and demanding driving conditions, having a sealant that can handle the jandal is a must. It’s the kind of gear that keeps you moving, rain or shine, and saves you hassle down the line.
