2.75-Inch Inside Diameter
The TS-HE45275-BK features a nominal 2.75-inch inside diameter, equivalent to approximately 69.9mm.
Both ends have the same nominal inside diameter, allowing the elbow to connect two sections of compatible 2.75-inch outside-diameter piping.
This makes it suitable for custom turbocharger systems, intercooler connections, and performance intake applications requiring a consistent pipe diameter.
Important: Always measure the outside diameter of the existing piping before ordering. A 2.75-inch coupler should not be confused with a 2.5-inch or 3-inch coupler.
45-Degree Elbow Design
The 45-degree bend provides a gradual directional change between two sections of piping.
This is particularly useful when intake or charge piping must route around the radiator, intercooler, engine accessories, or other components without requiring a sharp 90-degree turn.
The elbow can also simplify custom piping fabrication by reducing the need for additional welded bends.
102mm Leg Dimension
Turbosmart's published technical catalog identifies a 102mm leg dimension for the TS-HE45275-BK.
This provides approximately 4 inches of length for installation on compatible piping.
The hose may be trimmed when appropriate, provided sufficient straight material remains for secure pipe engagement and clamp placement.
Always verify the available installation space before modifying the hose.
Four-Ply Reinforced Silicone Construction
The TS-HE45275-BK features four-ply reinforced silicone construction.
The multiple reinforcement layers help provide strength and dimensional stability when exposed to pressure and temperature changes.
This construction is particularly beneficial in turbocharged applications where charge piping connections experience repeated boost pressure cycles.
The reinforced design also helps resist deformation compared with many conventional unreinforced rubber connectors.
5mm Wall Thickness
The elbow incorporates a 5mm wall thickness.
This reinforced wall construction provides durability while retaining the flexibility needed for installation between rigid piping sections.
It also helps the coupler accommodate minor vibration and movement during normal engine operation.
220 PSI Pressure Rating
Turbosmart rates this silicone elbow for pressures up to 220 PSI.
This is the manufacturer's hose pressure rating and should not be interpreted as a guarantee that an assembled piping connection will safely withstand that pressure.
Actual connection integrity depends on:
Pipe diameter and surface condition.
Properly formed pipe-end retaining beads.
Clamp selection and installation.
Operating temperature.
Piping alignment.
Hose condition.
For turbocharger charge piping, properly sized clamps and adequate pipe-end retention are essential.
High-Temperature Silicone Construction
The TS-HE45275-BK is designed for continuous operating temperatures between approximately -50°C and 170°C.
Its reinforced silicone construction provides resistance to elevated engine bay temperatures, making it suitable for many intake and intercooler piping applications.
However, the elbow should not be installed in direct contact with exhaust manifolds, turbocharger turbine housings, or other surfaces that exceed its rated temperature range.
45-Degree vs. 90-Degree Silicone Elbows
A 45-degree silicone elbow provides a more gradual change in piping direction than a 90-degree elbow.
The TS-HE45275-BK is ideal for applications requiring a moderate directional change while maintaining a 2.75-inch inside diameter.
For installations requiring a sharper turn, a properly sized 90-degree silicone elbow may be more appropriate.
Silicone Elbow vs. Silicone Reducer
The TS-HE45275-BK is an equal-diameter elbow.
Both ends have the same nominal 2.75-inch inside diameter.
It is not designed to transition between different pipe sizes.
For applications requiring a change in pipe diameter, select a properly sized silicone reducer instead.
Black Silicone Finish
The black finish provides a clean, understated appearance that complements a wide range of performance engine bay configurations.
It pairs well with black or polished aluminum intercooler piping, stainless steel charge pipes, aftermarket intercoolers, and custom turbocharger installations.
Silicone vs. Conventional Rubber Hoses
Reinforced silicone hoses offer several advantages over many conventional rubber connectors in demanding air piping applications.
These include:
Improved resistance to elevated temperatures.
Greater resistance to hardening and cracking.
Reinforced construction for pressurized systems.
Flexible installation characteristics.
Long-lasting performance when properly installed.
Actual durability depends on operating conditions, installation quality, and maintenance.
Recommended Hose Clamps
The TS-HE45275-BK should be secured using properly sized hose clamps suitable for the application.
For turbocharger charge piping, high-quality T-bolt clamps are commonly used.
Clamp selection must account for the coupler's outside diameter, including its 5mm wall thickness.
Important: Hose clamps are not included and must be purchased separately.
Oil and Chemical Compatibility
Standard silicone elbows are primarily intended for air and charge piping applications.
They are not designed for continuous exposure to fuel, engine oil, or other petroleum-based liquids unless specifically approved for that use.
Applications involving significant oil contamination may require a specially lined hose.
Verify material compatibility before using this elbow outside its intended air piping application.
