The DC Sports 2.5 inch silicone coupler is a no-drama way to join intake, intercooler, and charge pipes without worrying about blown connections. If you’re working with 2.5" piping, this 2.5 inch engine coupler gives you a solid, leak-resistant link that actually holds up in a hot, cramped engine bay.
This DC Sports silicone coupler uses a multi-ply, temperature resistant polyester reinforced silicone compound that we’ve run on turbo and supercharged builds for years. The reinforced silicone coupler won’t suck shut under vacuum or balloon under boost, and it keeps its shape after countless heat cycles. If you’re pushing a boosted setup or a hard-driven NA combo, this silicone engine coupler is built for exactly that kind of use.
The straight 2.5 inch hose coupler layout and compact 2.5 inch length work well in tight bays where every millimeter matters. The smooth bore helps maintain consistent airflow, and the flexible body soaks up engine movement so you’re not stressing your pipes, clamps, or welds. Whether you’re refreshing an intake, dialing in an intercooler setup, or building custom charge piping, this DC Sports fitting coupler / DC Sports hose connector goes on with normal T-bolt or worm clamps, no special tools, no weird adapters.
Rated for continuous use up to 350°F, this high temp silicone coupler is happy living near manifolds, radiators, and other hot spots. The durable silicone coupler construction and black finish keep things low-key and clean, so it blends in with OEM plastics or polished aluminum and makes visual checks for leaks, oil, or rubbing points quick and easy.
We use this same DC Sports intake coupler on our own cars, from daily drivers to track toys. If you’re hunting for a performance silicone coupler that isn’t going to split, sag, or discolor after a season, this DC Sports silicone coupler is the kind of temperature resistant coupler you bolt on once and stop thinking about.
