The HPS Performance Products HTSER90-138-150-BLK is a high-quality silicone hose designed for those who demand reliability and performance. This 90-degree elbow reducer coupler is crafted from a 4-ply reinforced high-temperature material that not only meets but exceeds the SAEJ20 standard, ensuring it can handle extreme conditions with ease.
Engineered for versatility, the HTSER90-138-150-BLK features a smooth transition from 1 3/8 inches to 1 1/2 inches (35mm to 38mm), making it ideal for a variety of applications. Whether you're working on high-performance racing vehicles, commercial trucks, or even agricultural machinery, this silicone hose is built to withstand varying pressure ranges and temperatures, from -65°F to +350°F (-54°C to +177°C).
One of the standout features of this product is its robust construction. The 4-ply design, made from premium knitted polyester fabric and high-temperature silicone rubber, ensures durability and flexibility. Customers have noted that the tight radius of the elbow reduces the risk of connections coming apart, which is crucial for maintaining the integrity of your setup. As one user put it, “I’ve used these hoses in my racing rig, and they’ve held up beautifully under pressure. No leaks, no issues!”
With an outside diameter of 1 3/4 inches to 1 7/8 inches (45mm to 48mm) and a wall thickness of 5mm, this hose is engineered to provide a secure fit that can handle the rigors of demanding environments. The elbow leg length on each side is 4 inches, allowing for easy installation in tight spaces.
