TuoLauthon 4in (102mm) 45° Silicone Elbow Coupler — 4-Ply, 5mm Wall with Clamps

This reinforced 45° silicone elbow combines four plies of high-grade silicone and anti-aging materials to deliver flexible, pressure-resistant connections where a right-angle bend is needed. With a 5mm wall thickness and supplied stainless clamps, it’s engineered to withstand wide temperature swings and resist UV, ozone and general wear, while being unsuitable for oil or fuel transfer.

How does this 45° elbow handle high temperatures and pressure?

The TuoLauthon silicone construction is rated to operate from -76°F (-60°C) up to +500°F (+260°C). Its 4-ply reinforcement gives the coupler strong compression and burst resistance so it keeps seal integrity under boost or thermal cycling.

• Working temperature range: -76°F to +500°F (-60°C to +260°C).
• Working pressure band: 0.3–0.9 MPa (43.5–130 PSI); bursting pressure up to 2 MPa.
• 5 mm wall thickness for added durability and kink resistance.

Will this elbow fit my 4-inch intercooler or intake piping?

This part has a nominal inner diameter of 4 inches (102 mm) and each leg length measures approximately 4 inches (102 mm), making it a direct fit for standard 4" systems. The included pair of stainless clamps secures the connection without the need for extra hardware.

• ID: 4 inch (102 mm); two legs at about 4 inch length each.
• Comes with 2 stainless steel clamps; no additional purchase required.
• Best for silicone-to-silicone or silicone-to-metal couplings on 4" lines.

Is this hose suitable for marine or industrial use?

Yes — the silicone formulation resists UV exposure and ozone, and the reinforced structure tolerates the vibration and temperature swings common in marine and industrial settings. However, this silicone coupler is not designed for oil or fuel transfer applications.

• UV and ozone resistant for outdoor and marine exposure.
• Reinforced 4-ply build handles vibration and pressure spikes.
• Not suitable or rated for direct oil or fuel transfer.

How will the package and installation look?

The product ships as a single 45° elbow coupler with two stainless clamps already included, ready for installation. Installation is straightforward: slide the elbow onto each pipe end, position clamps over the overlap, then tighten to the recommended torque for a secure, leak-resistant seal.

• Contents: 1 x 45° silicone elbow, 2 x stainless steel hose clamps.
• Pre-measured dimensions simplify selection for 4" systems.
• Typical tools: screwdriver or socket for clamp tightening; no special tools required.

Who is this for: The TuoLauthon 4" 45° 4-ply silicone elbow is aimed at DIY mechanics, performance tuners, marine equipment technicians and industrial maintenance teams who need a durable, heat-tolerant elbow for 4-inch piping. Choose this coupler when you require a reinforced, long-lasting silicone joint that tolerates temperature extremes, UV exposure and pressure cycling but is not intended for fuel- or oil-line use.
