Tyeioms 4" Silicone 90° Elbow Coupler - 4" ID x 4" Legs, 4-Ply Reinforced High-Temp

The Tyeioms 90 Degree Elbow is a reinforced 4" inner-diameter silicone hose coupler built for turbo, intake, and industrial connections that need flexible temperature and pressure resistance.

This 4" ID, 4" leg-length silicone elbow combines high-temperature durability with a four-ply reinforced wall to deliver a dependable, flexible joint for automotive and industrial plumbing. It replaces brittle or undersized connectors, offers consistent bore flow through the elbow, and is designed to resist heat, cold, and moderate boost pressure while maintaining shape under load.

How does this silicone elbow handle heat and cold?

The Tyeioms elbow is formulated to remain flexible from extreme cold to high heat, so it won't crack in winter or soften excessively under engine temperatures. Its material range supports many common thermal conditions encountered in vehicle and machinery use.

• Temperature tolerance: -60℃ (-140℉) to 260℃ (500℉)
• Stable elasticity across the rated range
• Suitable for both ambient and elevated under-hood temperatures

How strong is the elbow against pressure and mechanical stress?

This coupler uses a four-ply reinforced construction to increase burst and working pressure capacity, delivering greater reliability than single-layer silicone hoses. It’s intended for applications with moderate boost or compressed-air scenarios where a reinforced elbow is preferred.

• Reinforced 4-ply wall for improved structural integrity
• Rated pressure resistance up to 2 MPa
• 5 mm wall thickness provides rigidity without excessive bulk

Will this fit my system and how do I check compatibility?

The elbow’s inner diameter and leg length are the primary fit factors: both are 4" (102 mm). Verify those dimensions against your piping, clamps, or flanges before installation to ensure a correct seal and uninterrupted airflow.

• Inner diameter: 4" (102 mm)
• Leg length: 4" (102 mm) each side
• Confirm clamp diameter and mating part geometry for a proper fit

What applications is this coupler commonly used for?

The Tyeioms 90° elbow suits automotive intake and cooling plumbing, turbo inlet/outlet transitions, and industrial ducting where a robust, flexible right-angle connection is required. It’s a practical choice when routing constraints demand a durable 90-degree turn.

• Cold air intakes and turbo plumbing
• Intercooler piping transitions and charge-air systems
• General industrial hoses and compressed-air routing

Package contents and construction details: the product ships as one 90 Degree Elbow with a 4" inner diameter and 4" leg lengths, and a 5 mm wall thickness. The reinforced build is intended to reduce deformation under pressure and extend service life compared with non-reinforced silicone bends. Always verify measurements and select the correct size for your installation.

Who is this for: technicians, mechanics, and DIY enthusiasts who need a durable 90° silicone connector for turbo, intake, or industrial hose runs will find this Tyeioms elbow useful. It’s especially appropriate when you require a heat-resistant, pressure-capable, flexible joint that preserves airflow and resists cracking over repeated cycles.
