Automotive hose coupler engineered to join different hose diameters with durable, high-temperature silicone. Practical for home mechanics and garage workshops looking for a robust step-down connection, AP Automotive Straight Reducer Hose Coupler. Could this simple reducer be the dependable link missing from many intercooler and intake systems?
⚡ At a Glance
- • Temperature Resistance: Handles -60°C to +180°C thanks to high-temperature silicone
- • Best for: DIY car enthusiasts and mechanics needing a reliable hose reduction
- • Not ideal for: Precision OEM applications requiring manufacturer-specific fittings
Straight reducer connects 38mm to 25mm internal diameter across a 127mm length. Reinforced silicone construction with 4.5mm wall thickness and three textile plies resists ozone, UV and moisture.
Secure, vibration-resistant join – with 3-ply polyester reinforcement
Three textile reinforcement layers sit between silicone skins, increasing tensile strength and maintaining bore shape under flex and movement. A 4.5mm wall thickness adds stiffness that reduces collapse during pulsation.
Durable reinforcement keeps hose form under engine-bay movement and vibration, helping clamps maintain a reliable seal. Less chance of softening or deformation over prolonged use.
Wide working temperatures – thanks to high-temperature silicone
Silicone formulation rated from -60°C to +180°C resists thermal ageing and remains flexible across extremes. Material resists common environmental aggressors such as ozone, UV and moisture.
Suitable for hot engine bays and cold climates without brittle behaviour or loss of flexibility. Stable performance reduces need for frequent replacements.
Straight step-down fit – with 38mm to 25mm internal diameters over 127mm length
Internal bore steps from 38mm to 25mm along a 127mm hose length, creating a gradual reduction rather than an abrupt join. Straight profile allows straightforward clamp placement at each end.
Easy to incorporate into intercooler or intake plumbing where a size reduction is needed. Generous length supplies overlap for standard hose clamps and reliable joins.
✨ The 4 Key Reasons for AP Automotive Straight Reducer Hose Coupler
- 4.5mm Wall Thickness – Reduces collapse risk, maintaining shape during high-flow conditions
- 3-Ply Polyester Reinforcement – Adds strength for long-term durability in engine bays
- Universal Fitment – Fits a wide range of cars, trucks and custom intercoolers
- 127mm Length – Provides enough overlap for secure hose clamps and joins
