HPS Performance HTSEC90-075-L5X24-BLK Silicone Elbow Coupler Hose ID Black - 90-Degree 3/4 4-Ply

The HPS Performance HTSEC90-075-L5X24-BLK is a high-temperature, 4-ply reinforced silicone 90-degree elbow coupler hose featuring asymmetric leg lengths of 5" and 24" with a 3/4" (19mm) inside diameter. Designed and engineered to meet and exceed SAE J20 industry standards, this silicone elbow coupler is built to outperform traditional rubber hoses in demanding pressure and temperature environments.

Constructed from premium polyester-knit reinforced silicone rubber, this coupler can be easily trimmed to length, making it a versatile replacement for OEM or aftermarket rubber heater hoses. It is well suited for automotive, marine, and industrial applications including radiator cooling systems, heater hose routing, supercharger aftercoolers, and air-to-water heat exchangers.
