If you want a long, straight section to bridge wide gaps in your pickup truck's intake or cooling system, choose LYHARNYX ID 1.5; if you need a compact, angular connector to transition between smaller diameter pipes, choose Haturmyko ID 1"-1.25.
• LYHARNYX ID 1.5: Offers a generous 12-inch length and a consistent 1.5-inch bore for flexible routing, but its straight geometry requires space that might not exist in tight engine bays. Best for builders needing custom-length runs.
• Haturmyko ID 1"-1.25: Provides a specialized 90-degree elbow to change direction and reduce pipe size, yet its fixed 7-inch legs limit reach and it only fits specific diameter transitions. Best for confined spaces needing a turn.
• Both utilize 4-ply reinforced silicone with identical burst pressure ratings, ensuring they handle high heat and pressure equally well.
• The choice ultimately depends on whether your project demands a long, straight run or a tight, angled reduction.
The LYHARNYX ID 1.5 is built for situations where distance and consistency matter most. With an inner diameter of exactly 1.5 inches and a total length of 12 inches, this hose serves as a versatile bridge in complex piping systems. Its primary strength lies in its universal design; because it is a straight coupler, you can trim it down to whatever specific length your installation requires without compromising the internal flow area. This makes it an ideal candidate for fabricating custom intake manifolds or extending coolant lines across the frame of a vehicle where standard off-the-shelf parts simply won't fit.
I see this product as the go-to solution for serious automotive enthusiasts working on performance builds, particularly those upgrading their pickup trucks. The ability to operate stably from -76°F to 374°F means it will handle the intense heat generated by turbochargers and intercoolers without degrading. Furthermore, the 4-layer fiber reinforcement provides a level of structural integrity that prevents the hose from collapsing under negative pressure or bursting under high boost. If you are running a large turbo setup or need to route a hose around a massive radiator fan, the extra length and flexibility of the LYHARNYX allow you to snake the tubing through tight spots while maintaining a smooth airflow path.
However, this hose is not a one-size-fits-all answer for every scenario. Its straight configuration means it cannot navigate corners or changes in direction on its own. If your plumbing layout requires a sharp turn or a connection between two pipes of different sizes, this straight tube will force you to buy additional fittings, adding complexity and potential leak points to your build. Additionally, while the 1.5-inch diameter is excellent for high-flow applications, it might be overkill for smaller, stock-level systems where a narrower hose would suffice. You should skip this product if your project involves connecting a 1-inch pipe to a 1.25-inch pipe or if you have zero clearance for a 12-inch straight run.

The Haturmyko ID 1"-1.25 takes a completely different approach by combining three functions into a single unit: reducing diameter, changing direction, and providing a short connection. As a 90-degree reducer, it connects a 1.25-inch pipe to a 1-inch pipe while simultaneously angling the flow. This specific geometry is invaluable when you are trying to tuck piping into tight engine compartments or connect components that are offset from one another. The 7-inch leg length offers just enough reach to clear obstacles without taking up excessive space, making it a perfect fit for compact installations where every inch counts.
For owners of modified vehicles who need to adapt existing plumbing to new hardware, this reducer is a practical tool. The pure silicone construction with 4-ply reinforcement ensures that despite the thinner walls relative to some heavy-duty hoses, it still maintains durability against abrasion and vibration. It handles temperatures up to 300 degrees Fahrenheit and withstands burst pressures of 1 MPa, which covers the vast majority of street and light track applications. I recommend this piece for anyone dealing with intercooler piping where the inlet and outlet are at different heights or angles, or for turbo setups where the exhaust gas path needs to bend sharply away from the engine block.
That said, the Haturmyko has limitations inherent to its specialized design. Because it is a fixed 90-degree elbow, you lose the ability to adjust the angle of the connection. If your mounting points do not align perfectly with a right angle, you may struggle to install it without forcing the components, which could stress the silicone. Moreover, the reduction from 1.25 inches to 1 inch creates a restriction point in the airflow compared to a straight, constant-diameter hose. While this is often necessary for fitting specific components, it is not ideal for maximizing flow in a high-horsepower application where every fraction of an inch matters. Avoid this part if you need a longer connection or if both sides of your connection require the same diameter.
• Best for custom length adjustments → LYHARNYX ID 1.5: You can cut this hose to any length, whereas the Haturmyko is a fixed 7-inch shape.
• Best for navigating tight corners → Haturmyko ID 1"-1.25: The 90-degree angle allows you to bypass obstacles that a straight tube cannot.
• Best for high-flow, unrestricted paths → LYHARNYX ID 1.5: The constant 1.5-inch bore minimizes turbulence compared to a reducer.
• Best for transitioning between pipe sizes → Haturmyko ID 1"-1.25: It seamlessly bridges the gap between 1.25-inch and 1-inch diameters in one step.
• Best for long-distance routing → LYHARNYX ID 1.5: At 12 inches, it spans larger gaps than the 7-inch legs of the reducer.
• Best for compact engine bays → Haturmyko ID 1"-1.25: The shorter profile saves valuable space in crowded setups.
• Highest temperature tolerance → Tie: Both units feature silicone capable of handling extreme heat, though the LYHARNYX lists a slightly higher max (374°F vs 300°F).
• Ease of installation for beginners → Haturmyko ID 1"-1.25: Fewer cuts and fittings are needed for simple 90-degree connections.
In my opinion, the LYHARNYX ID 1.5 is the superior choice for most pickup truck projects because versatility wins out in fabrication work. Being able to trim the hose to the exact length required and maintain a full 1.5-inch bore gives you significantly more freedom when designing a custom intake or cooling system. The Haturmyko reducer is undeniably useful for specific, tight turns, but its fixed dimensions and reduced diameter make it a niche solution. Unless you are specifically fighting for space and need to drop from 1.25 to 1 inch immediately, the straight hose offers a cleaner, more robust path for air and fluid. I would buy the LYHARNYX first for a general build, keeping the reducer on hand only for that one specific corner case.
Yes, both products feature 4-ply reinforced silicone capable of withstanding burst pressures of 1 MPa and operating temperatures well above typical street driving conditions.
The LYHARNYX ID 1.5 has a slightly broader operating range, rated up to 374°F (-60°C to 190°C), compared to the Haturmyko's rating of 300°F (-60°C to 148°C).
Yes, both manufacturers list compatibility with marine, racing, and industrial uses, including coolant, air, water, and steam systems, provided the diameter and temperature requirements match your application.
