OHOB-COOL 3" ID 45° Silicone Elbow Coupler — 4‑Ply Reinforced, 5mm Wall, 4" Length

OHOB-COOL's 45° 3" ID silicone elbow is a reinforced 4-ply coupling engineered for turbo, intercooler, intake and hydraulic transitions where high heat and pressure resistance are required.

This reinforced silicone 45-degree elbow joins two 3" (76 mm) pipes with a compact 4" length and a 5 mm wall thickness, offering a flexible, durable connection for performance and industrial systems. Built with four reinforcement layers, it bridges misaligned components while tolerating wide temperature swings and moderate operating pressures. The design supports turbocharger plumbing, intercooler piping, intake snorkels and hydraulic transition points where a short, angled silicone joiner is needed.

How does this elbow perform under high temperatures and cold starts?

The silicone compound maintains flexibility and dimensional stability from -76°F up to 500°F (-60°C to 260°C), so it resists cracking in extreme cold and softening at elevated temperatures common in engine bays. That thermal range helps preserve the seal and reduces the chance of failure from thermal cycling.

• Wide operating temperature: -76°F to 500°F (-60°C to 260°C)
• Silicone resists heat aging and cold embrittlement
• Stable under repeated thermal cycles

Is this elbow strong enough for turbocharger and intercooler systems?

Yes—the component uses a four-ply reinforcement and a 5 mm wall thickness to handle moderate boost and pressure differentials typically found in turbo and intercooler plumbing. It isn’t intended for extremely high-pressure hydraulic circuits but performs reliably for intake and charge-air duties.

• Inner diameter: 3" (76 mm) suited to many performance pipes
• Pressure capability: approximately 0.3 to 0.9 MPa depending on clamp and system conditions
• 4-layer reinforcement improves burst and kink resistance

How easy is it to install and fit in tight engine bays?

The short 4" overall length and 45° angle make this elbow ideal for compact routing where a gentle offset is needed. Its flexible silicone body allows minor misalignment compensation, and standard hose clamps or quick-connect fittings can secure it to existing tubing.

• Compact length: 4" overall for tight installations
• 45° bend reduces stress on adjacent hoses and clamps
• Compatible with standard 3" hose clamps and couplers

What are the key specifications and material benefits?

This coupler combines silicone’s chemical stability with a multi-ply reinforcement for a balance of flexibility and strength. It’s tailored for automotive and industrial air or low-to-moderate pressure fluid transition duties where temperature extremes and repeated vibration are concerns.

• ID: 3" (76 mm) with 4" overall length
• Wall thickness: 5 mm; construction: 4-ply reinforcement
• Temperature range: -76°F to 500°F (-60°C to 260°C)
• Pressure range: ~0.3 MPa to 0.9 MPa depending on system

Who is this product for? This OHOB-COOL 45° silicone elbow is aimed at mechanics, tuners and maintenance professionals who need a short, durable angled connector for turbo, intercooler or intake plumbing and for industrial applications that require reliable thermal tolerance and moderate pressure handling. Choose this part when you need a compact, reinforced silicone transition that resists heat, vibration and repeated use in demanding environments without the bulk of longer pipes or rigid fittings.
