Taukealugs Straight Reducer Coupler Silicone Hose ID

Taukealugs straight reducer coupler is a 4-ply reinforced silicone hose that joins 3.75" (95 mm) to 4" (102 mm) pipes and includes a stainless steel T-bolt clamp for secure turbo, intercooler, and intake connections.

If you need a durable, heat-resistant link between slightly different-diameter charge pipes, this Taukealugs silicone coupler provides a tight, long-lasting seal without sacrificing airflow. Built from multi-layer silicone with embedded reinforcement, it handles wide temperature swings and the pressures typical of turbocharged systems. The included stainless steel T-bolt clamp helps deliver even radial compression for a reliable, leak-resistant fit.

How does this coupler handle high under-hood temperatures?

The coupler is constructed from high-temperature reinforced pure silicone rated from -60°C to 230°C (-140°F to 428°F), so it resists softening, cracking, or becoming brittle across normal automotive operating ranges. The multi-ply design adds structural integrity and helps keep the hose stable under thermal cycling.

• Operating range: -60°C to 230°C (-140°F to 428°F)
• 4-ply reinforced silicone for long-term heat resilience
• Designed for turbo and intercooler environments

Will it fit my 3.75" to 4" intake or intercooler piping?

This Taukealugs straight reducer is sized specifically to join 95 mm (3.75") to 102 mm (4") pipes, so it works where those diameters meet. The elastic nature of silicone and the included T-bolt clamp let you fine-tune the compression for a secure, leak-free junction.

• Inner diameters covered: 95 mm to 102 mm (3.75" to 4")
• Stretch and flex accommodate minor dimensional variance
• Includes one stainless steel T-bolt clamp for even sealing

How strong and pressure-resistant is the coupler?

The reinforced construction supports elevated boost pressures typical in many turbo applications with a bursting pressure around 2 MPa, and the multi-layer build resists ballooning under load. For safety and longevity, pair it with proper clamps and avoid exceeding recommended system pressures.

• Bursting pressure approximately 2 MPa
• 4-ply reinforcement resists deformation under boost
• Stainless T-bolt clamp provides uniform clamping force

What installation tips improve fit and lifespan?

Clean pipe ends, apply a light silicone-safe lubricant if needed, and position the coupler so it slides fully onto each pipe before tightening the clamp evenly. Avoid over-tightening the T-bolt clamp—tighten until the seal is snug without pinching the silicone—and check connections after the first heat cycle.

• Ensure mating pipes are clean and free of burrs
• Tighten clamp evenly until snug, not crushed
• Re-check seals after first heat cycle and periodically thereafter

Who is this for? Tuners, DIY mechanics, and performance shops needing a dependable reducer for turbo, intercooler, or intake piping will appreciate this Taukealugs coupler. It’s ideal when you must join closely sized pipes with a heat-resistant, reinforced silicone solution plus a stainless T-bolt clamp for an evenly compressed seal. Choose this product when durability, temperature tolerance, and reliable sealing matter for forced-induction or high-performance airflow systems.
