Alright, let’s talk about the HPS 7/8" (22mm) silicone hump coupler hose. If you're diving into some heavy-duty work or just need a reliable connection for your custom setups, this is the piece you want in your arsenal. With a length of 6 inches, it’s got the right size for a variety of applications, whether you’re tackling turbo piping or setting up a DIY intake system.
This hose is built to last—it's made from a 4-ply reinforced silicone that can handle temperatures from a chilly -65°F to a scorching 350°F (that’s about 177°C for those who prefer metric). So, if you’re pushing your engine hard or dealing with some hot air in your cooling system, it’s got your back. Just keep in mind, this silicone isn’t fuel or oil resistant, so steer clear of those fluids.
One of the standout features is its ability to compensate for misalignment and dampen vibrations. That means you can install it without worrying about it causing issues down the line. Plus, it’s UV and ozone resistant, so you won’t have to stress about it deteriorating under the sun or in harsh conditions.
Here’s the nitty-gritty on the specs:
So, if you’re looking for a solid, reliable coupler hose that can take the heat (literally), this HPS option is a no-brainer. Whether you're in the garage fabricating your dream setup or working on a marine project, it’s got the durability and performance to get the job done.
