Every set contains the same three couplers, sized to cover the transitions most piping setups need:
Beneath them, six stainless worm-gear clamps, diameters matched to the couplers above. Pre-matched, so you never discover at install time that your clamps are a size off.
Those raised ridges aren't decoration. They're reinforcement. Each ridge creates an independent sealing zone — if one section sees stress, the others still hold. And the ridge structure helps the coupler resist collapse under vacuum while staying rigid under boost. That's the difference between a connection that lasts a season and one that lasts the life of the build.
The display shows nine colors — golden yellow, greyish-blue, bright red, deep green, lime, orange, purple, white, and dark blue. And there's a tenth: black, the baseline color every build needs.
Every color meets the same standard — high-temperature silicone rated for charge-air and cooling circuits, reinforced ridge construction, stainless hardware that won't rust in the engine bay. No renders, no "colors may vary" fine print. What you see is what you get.
For builders, the color is the point. Match the piping. Match the valve cover. Match the theme of the build — or keep it clean and stealthy with black.
For shops and distributors, this is a stocking decision made simple: one kit covers three coupler sizes, the clamps, and a ten-color range that fits almost any customer's theme. No loose inventory of mismatched sleeves. No "do you have this size in red?" phone calls. The customer gets a complete, color-matched solution — you get the sale without the hunt.
These multi-ridge couplers suit intercooler piping, intake systems, and charge-air connections where pipe sizes transition.
Confirm your required diameter range with us before ordering — we'll match the kit to your piping sizes.
