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

TuoLauthon’s 2.5-inch (63mm) 45° 4-ply silicone elbow coupler is a heavy-duty, high-temperature hose designed to join intercooler, turbo, supercharger, or intake plumbing with reliable flexibility and reinforced strength.

If you need a compact, durable elbow to reroute boosted air or intake flows where space or angle constraints exist, this silicone coupler delivers a balance of flexibility and pressure tolerance. Built from four layers of reinforced high-grade silicone with a 5mm wall thickness, it resists heat, ozone, and UV exposure while remaining pliable across a wide temperature range.

How hot and cold can this silicone elbow handle?

The TuoLauthon 4-ply silicone formula is formulated for extreme temperature swings, so it maintains shape and performance in demanding engine bays and marine environments. It won’t become brittle in extreme cold or soften dangerously in high heat within its rated range.

• Operating temperature range: -76°F (-60°C) to +500°F (+260°C)
• Working pressure: 0.3–0.9 MPa (43.5–130 PSI)
• Bursting pressure: up to 2 MPa
• Wall thickness: robust 5 mm for durability

Will this elbow work with my turbo or intercooler setup?

This 45° elbow is intended for universal application across intercoolers, turbochargers, superchargers, and intake plumbing where a precise angled coupling is required. It’s not formulated for oil or fuel transfer, but it performs well for boosted air and coolant-air routing on automotive and marine systems.

• Inner diameter (ID): 2.5 inches (63 mm) for standard boost plumbing
• Leg length: 4 inches (102 mm) each side for convenient clamp placement
• Includes two stainless steel clamps—no extra purchases needed
• UV and ozone resistant for outdoor or marine exposure

How strong and flexible is this 4-ply construction?

The four-layer construction combines multiple reinforcing layers with high-quality silica gel and anti-aging compounds to provide compression resistance and high-pressure stability without sacrificing flexibility. This makes the elbow suitable for repeated thermal cycles and vibration-prone installations.

• 4-ply reinforcement for improved burst and working pressures
• High compression resistance to hold shape under clamp load
• Designed for long service life in harsh environments

How easy is it to install and maintain this coupler?

Installation is straightforward: slide the elbow over pipe ends, position the clamps, and tighten. The included stainless clamps help ensure a secure seal and resist rust, simplifying both initial fitment and later maintenance.

• Comes with two stainless steel clamps—ready to install
• Flexible enough for slight alignment adjustments during fitment
• Wipe-clean silicone surface; inspect clamps and joints periodically

Who is this for? This TuoLauthon 45° 2.5-inch elbow is aimed at mechanics, performance enthusiasts, marine installers, and industrial technicians who need a compact, heat-resistant coupler for air or coolant routing. Choose this part when you require a reinforced silicone elbow that tolerates high temperatures and pressures, fits common 63mm systems, and arrives ready to install with stainless clamps. Note: not suitable for fuel or oil transfer applications.
