Flex Technologies 90-degree preformed coolant hoses: silicone elbows with 10-inch legs for radiator, heater and coolant connections where a straight hose would kink. There are 34 listings: 18 sizes in black and 16 in blue.
Each listing is titled by inside diameter and color (for example 1.25in I.D. 90 Degree Preformed Coolant Hose, Black). Both colors are offered in the 0.50, 0.75, 1.00, 1.125, 1.25, 1.375, 1.50, 1.75, 2.00, 2.25, 2.50, 2.75, 3.00, 4.00, 5.00 and 6.00 in. sizes; 3.50 and 4.50 in. are black only.
To size one, measure the outside diameter of the pipe or fitting the hose slides over; that is the hose I.D. you need. For a different diameter on each end, see 90-degree reducers; for other angles, 45-degree hoses; and for straight runs, straight stick hose. The full range is in Flex Technologies.
