2.5" Silicone 180 Degree Elbow Coupler - Black | High-Temp Performance Hose | PFES106-250B

This Proflow 2.50in. 180 Degree Silicone Elbow is designed to fit systems with a 2.5-inch (63mm) outside diameter at the connection points. Double-check the diameter of your pipes and confirm you need a 180-degree bend before ordering. It's a universal fit for many fabrication projects, especially custom air intakes, heating, and cooling applications. If you're not sure, measure your existing tubing and compare to ensure a snug, leak-free fit.

The Proflow hose uses premium 4-layer, polyester-reinforced silicone, making it much more durable than typical rubber couplers. It can handle extreme temperatures (-60°C to 180°C) and withstands up to 200 PSI of burst pressure. Silicone is highly resistant to heat, pressure, and aging, making it a long-lasting upgrade for demanding automotive applications.

Installation is straightforward—no special tools required! Just slide the elbow over your existing 2.5-inch pipes and secure with high-quality hose clamps (sold separately) for a tight seal. The flexible silicone material makes fitting easier, even in tight engine bays. For best results, clean and dry all mating surfaces before installing to prevent leaks.

Absolutely! This Proflow silicone elbow is incredibly versatile. It's suitable for air intake, intercooler, coolant, and general heater hose routing. Its 4-layer, 5mm construction resists both high heat and pressure, so it's ideal for turbocharged engines and coolant lines. Just verify that the 2.5-inch diameter suits your specific setup before installation.

Silicone hoses generally require minimal maintenance. For best longevity, periodically inspect the elbow for signs of wear or damage, especially after long drives or high-performance use. Clean the exterior with mild soap and water—avoid harsh chemicals. Make sure hose clamps are properly tightened but not over-torqued to prevent cutting into the silicone. With proper care, your Proflow hose should provide years of reliable service.
