AC Performance ID 3/4" (19mm) 90 Degree Elbow Coupler – 3-ply reinforced silicone hose, black

If you’re building or tweaking automotive-style hose runs, a decent 90 degree elbow coupler is one of those parts you don’t really notice… until you’re missing it. The AC Performance 3/4" (19mm) 90 Degree Elbow Coupler is designed to help you route pure silicone hose in a tighter layout, with a reinforced, 3-ply structure made for higher temperatures and tougher environments.

This is a fairly “serious” hose fitting rather than a basic rubber connector. On paper, it’s aimed at fabrication jobs where you want the bend to survive heat cycles and daily exposure, whether that’s DIY intake plumbing, cooling connections, or custom turbo/intercooler piping.
