00:00Hey everyone! If you've ever dealt with a stubborn oil leak or you're tearing down an engine for a
00:05weekend rebuild, you know a reliable seal makes all the difference. Today, we're looking at the
00:10top 5 silicone sealants for gasket making, and I've tracked down the best deals online so you
00:15don't end up overpaying for your next garage project. Starting off with our most budget-friendly
00:20pick, this 85-gram waterproof engine sealant is sitting at a flawless 5-star rating with thousands
00:26sold. Its standout feature is its impressive high-temperature resistance, making it versatile
00:31enough for head gaskets, gearboxes, and water pumps. At just $4.72, it's an absolute steal that provides
00:39a rock-solid, watertight barrier without eating into your part's budget. Next up, we have this
00:45heavy-duty liquid RTV silicone made specifically for automotive repairs around oil pans and valve
00:51covers. What really makes this one shine is its exceptional resistance to hot engine oil on metal
00:56surfaces, curing into a flexible seal that won't shrink or crack under vibration. Coming in at $7.12,
01:04it's well worth picking up if you want total peace of mind against persistent, messy oil seepage.
01:09Moving on to number 3, we have this high-temperature black RTV gasket maker, and the killer feature here
01:15is the quick-drying formula. If you're on a tight timeline and need automotive parts bonded,
01:20sealed, and waterproofed without waiting overnight, this fast-curing silicone saves you serious time.
01:26Priced at only $6.59, it's a dependable, Lomas workhorse that belongs in every DIY mechanic's
01:33toolbox. In the fourth spot, the Sanbo 83-gram neutral silicone sealant brings serious heat
01:39defense to the table, handling temperatures up to 300 degrees Celsius with ease. Because it features a
01:45neutral cure, it won't corrode sensitive metals or sensors inside your engine and gearbox while
01:50still providing a fast, reliable set. At $6.74, it hits that perfect sweet spot of professional-grade
01:58thermal durability and everyday value. Finally, we have the mechanic favorite,
02:03the original L-Ring Durko HT. If you talk to engine builders, they swear by Durko HT because
02:09its permanently elastic silicone matrix laughs off extreme heat, coolant pressure, and aggressive
02:14synthetic oils. It sits at $9.34 for 70ml, but for critical seals where a leak means tearing the
02:22whole engine down again, it is worth every single penny. That wraps up our list. I've left all the
