HPS Performance Products HTSEC90-062-L5X12-BLK 90 Degree Silicone Elbow Coupler Hose 5/8" ID Black

The HPS Performance Products HTSEC90-062-L5X12-BLK is a high-temperature, 4-ply reinforced silicone 90-degree elbow coupler hose designed to meet and exceed SAE J20 industry standards. Built for durability and performance, this silicone coupler significantly outlasts traditional rubber hoses in demanding environments, making it an ideal upgrade for automotive, marine, and industrial applications.

With asymmetric leg lengths of 5" and 12", this coupler is well-suited for routing coolant, heater hose, or other water-based fluid lines where a standard equal-leg elbow won't fit. The longer 12" leg can be trimmed to length as needed to replace OEM or aftermarket rubber heater hoses.
