A 32mm outside diameter alloy bend, sitting between fine plumbing and proper charge-air pipework. It suits main coolant and heater runs, high-volume breather and catch can plumbing, and small intake or throttle body routing on modest engines. The rigid bend holds its bore through the corner, which matters on coolant circuits where a kinked hose quietly restricts flow and shows up as a hot spot rather than an obvious fault. Cut to length, deburr, and join with silicone couplers secured by suitable clamps. Check the coupler you plan to use is sized for 32mm, as silicone joiners are matched to outside diameter and will not seal reliably if mismatched.
