411 WORKS 90° Silicone Reducer Coupler

The 411 WORKS 90° Silicone Reducer Coupler is designed to connect two different tubing diameters while providing a 90-degree change in direction. Built for demanding automotive and motorsport applications, these couplers provide a flexible connection for charge piping, intercooler systems, water systems, and other compatible plumbing configurations. A reinforced multi-ply silicone construction provides strength and flexibility while supporting operation across a wide temperature range. Multiple sizes and wall thicknesses are available to accommodate different fabrication and plumbing requirements. 90° Reducing Design: Combines a 90-degree bend with a size transition, helping connect different tubing diameters in tight or complex plumbing layouts. Reinforced Silicone Construction: Features a multi-ply design with three reinforced silicone layers for strength and flexibility. High-Temperature Resistance: Rated from -120°F to +360°F, with peak temperature capability up to +390°F (-60°C to +200°C). Multiple Wall Thicknesses: Wall thickness varies by coupler size to support the requirements of larger diameter applications. Versatile Applications: Suitable for compatible charge pipes, intercooler piping, water systems, and other automotive or motorsport plumbing applications. In-House Tested: 411 WORKS tests its silicone couplers in-house, with burst pressure data available for applications requiring additional technical information. Available Size & Wall Thickness Ranges 1/2" to 1-7/8": 4mm wall thickness 2" to 2-3/4": 5mm wall thickness 3" to 6": 6mm wall thickness What's Included (1) 411 WORKS 90° Silicone Reducer Coupler in selected size Vehicle Fitment Universal application Suitable for compatible automotive and motorsport plumbing systems Designed for applications requiring a 90-degree bend and reduction between different tubing diameters Final compatibility depends on tubing dimensions, operating temperature, pressure, fluid type, and available clearance Specifications Brand: 411 WORKS Product Type: 90° Reducer Coupler Material: Silicone Configuration: 90° Reducing Construction: Reinforced Multi-Ply Temperature Range: -120°F to +360°F Peak Temperature: Up to +390°F Metric Temperature Range Provided: -60°C to +200°C Wall Thickness: 4mm / 5mm / 6mm depending on size Fitment: Universal Important Notes Sold individually. This is a universal component and is not vehicle specific. Verify both tubing diameters before selecting a reducer size. Wall thickness varies according to coupler diameter. Verify operating temperature, pressure, fluid compatibility, and clearance before installation. Burst pressure data is available from the manufacturer for applications requiring specific pressure information. Clamps are not included unless specifically stated. Properly sized clamps should be used to secure both ends of the coupler. Inspect the coupler and connections for leaks or movement before operating the vehicle. Do not exceed the manufacturer's specified temperature or pressure limitations.
