TuoLauthon 2.5" (63mm) 45° Silicone Elbow Coupler — 4-Ply, 5mm Wall with Clamps

TuoLauthon’s 2.5-inch (63mm) 45° 4-ply silicone elbow is a reinforced intake/intercooler coupler built for high heat and high pressure applications.

This angled silicone hose joins turbo, intercooler, supercharger or intake plumbing where a smooth 45° bend is needed without compromising strength. Constructed from four layers of reinforced high-grade silicone and durable anti-aging materials, it resists compression, ozone and UV degradation while tolerating extreme temperatures. The coupling ships with two stainless clamps so it’s ready to install on most 2.5" piping systems.

How durable is this silicone elbow under heat and pressure?

The TuoLauthon elbow is built for demanding thermal and mechanical environments. Its four-ply build and 5mm wall thickness improve burst and working pressure performance while the silicone compound resists aging from heat and ozone.

• Temperature tolerance ranges from −76°F (−60°C) up to +500°F (+260°C).
• Working pressure is rated between 0.3–0.9 MPa (≈43–130 PSI), with a bursting capability around 2 MPa.
• 5 mm wall thickness provides strong compression resistance in clamped connections.

Will it fit my setup and what hardware is included?

This elbow is sized to connect 2.5-inch (63 mm) inner diameter piping and features two 4-inch (102 mm) legs for straightforward installation. It’s a universal-style coupler suitable for many automotive and marine intake or intercooler layouts.

• ID: 2.5 in (63 mm) to match standard charge or intake piping.
• Leg length: 4 in (102 mm) to allow overlap with tubing and hose clamps.
• Includes two stainless steel clamps—no extra clamps required for typical installs.

Is this coupler suitable for oil, fuel, and marine use?

The hose is UV- and ozone-resistant and works well in marine and industrial settings where heat and weathering are concerns. It is not formulated for direct oil or fuel transfer; avoid using it as a primary fuel line.

• Recommended for intercooler, turbo, supercharger and intake plumbing.
• Good for marine and outdoor applications due to UV/ozone resistance.
• Not intended for conveying oil, gasoline, or other fuels.

Who is this for? Mechanics, fabricators and performance enthusiasts who need a reliable, high-temperature 45° silicone coupling for 2.5" systems will find this TuoLauthon elbow useful. It suits custom charge piping, turbo plumbing, and retrofit jobs where a durable angled connection is required. Because it ships with stainless clamps and uses robust materials, it’s especially handy for installations exposed to heat, vibration and outdoor conditions.
