HPS Performance Products 1" Blue Reinforced Silicone Coolant Cap, 3-Ply Polyester, 350°F
$23.79

If you’re looking to upgrade your cooling system, the HPS Performance 1" High Temperature Reinforced Blue Silicone Cap is a solid choice. This isn’t just any cap; it’s built to handle the heat and pressure that comes with high-performance setups. Unlike those flimsy vacuum caps that barely hold up, this one is reinforced with three layers of tough polyester webbing. Trust me, you’ll appreciate that extra durability when things heat up.

What’s cool about this cap is its versatility. You can use it with coolant, water, air, and even turbocharger bypass valve ports. It’s also handy for vacuum ports and throttle body water ports. Basically, if it’s part of your cooling system, this cap can probably handle it. Just keep in mind, it’s not meant for fuel, oil, or any petroleum-based products—so don’t go mixing things up!

Temperature-wise, it’s rated to handle a range from -65°F to a scorching 350°F (that’s about 177°C for you metric folks). The wall thickness is a sturdy 4mm, giving you peace of mind that it won’t buckle under pressure. The inside diameter is 1" (25mm), and it’s got an overall length of 1-5/8". This means it fits snugly without any fuss.

And let’s not forget about the aesthetics—this cap comes in a vibrant blue that not only looks good but is also UV and ozone resistant. It’s a small detail, but it adds a nice touch to your engine bay.

In a nutshell, if you want a reliable, heavy-duty cap that can take the heat and keep your cooling system running smoothly, the HPS silicone cap is worth considering. It’s built for the long haul, and you’ll appreciate the quality every time you pop the hood.
