SEMA 360 Showcase: DYME PSI Rattlesnake

The SEMA show was run as an online showcase from November 2 – 6 dubbed SEMA360. Comprising thousands of vendors, industry seminars and outside events all accessible in a virtual format.

I combed through the product section specifically looking for new or generally unknown products that would be of particular interest to the racing community and custom builders. One such item that immediately caught my eye was the Rattlesnake by DYME PSI.

What is the Rattlesnake?

In short the Rattlesnake is LEGO’s for -AN hoses and fittings. It is a kit consisting of modular ‘hose’ segments, virtually any assortment of end fittings and a fine adjustment dial. You use these to mock up the hose you need (end to end) and then relay the information back to DYME PSI where they will make the complete hose and ship it back ready to install.

There is a great walkthrough on DYME PSI website at :

Why use it?

Custom builders will see the value immediately as the Rattlesnake will increase workflow in the engine bay by eliminating the need to build hoses and easily create the most efficient plumbing for fluids.

And I’ve seen the rats nest of hoses some of you spec racers use. Particularly for oil coolers. This kit would definitely go a long way towards cleaning up your engine bay, allowing for the most efficient routing of hoses and ultimately increase reliability by reducing complexity.

So yeah, I think this is one of the coolest products I’ve seen this year. It addresses a very specific need with a very direct solution. There is a small investment cost with the kit and it will more than pay for itself after a few uses.
