Product Details
The Turbosmart 4mm Reinforced Silicone Vacuum Hose (TS-HVR0403-BK) is a premium performance vacuum and pressure reference hose designed for reliable operation in demanding automotive applications. Featuring a 4mm inner diameter, reinforced construction, and 3-meter (approximately 9.84-foot) length, this black vacuum hose provides a durable solution for turbocharger boost control systems, wastegate actuators, blow-off valves, and other vacuum-operated components.
Unlike conventional non-reinforced vacuum tubing, Turbosmart's reinforced hose incorporates strengthening material to improve durability and resistance to deformation under demanding operating conditions. This construction allows the hose to handle higher pressures than traditional vacuum hose while maintaining reliable pressure and vacuum signal delivery.
Accurate pressure reference signals are essential for proper turbocharger operation. Vacuum lines connect components such as boost control solenoids, wastegate actuators, and pressure sensors, allowing them to respond to changes in engine operating conditions. Damaged, deteriorated, or incorrectly sized vacuum hoses can introduce leaks and cause inconsistent component operation.
The TS-HVR0403-BK features a 4mm (approximately 5/32-inch) inner diameter and 9mm outer diameter, making it suitable for compatible fittings requiring a 4mm hose connection. Its 3-meter length provides enough material for multiple short connections or longer custom routing arrangements.
The black finish offers a clean, understated appearance that blends naturally into factory and aftermarket engine bays.
Whether replacing deteriorated factory vacuum lines, plumbing a new turbocharger system, or upgrading the pressure reference connections on a high-performance Honda K20/K24 build, the Turbosmart TS-HVR0403-BK Reinforced Vacuum Hose provides the strength, flexibility, and reliability needed for demanding forced-induction applications.

Reinforced Silicone Construction
The TS-HVR0403-BK features a reinforced hose design that incorporates strengthening material within the silicone construction.
This reinforcement improves the hose's ability to maintain its shape under demanding operating conditions.
Compared with conventional non-reinforced vacuum hose, the reinforced design offers greater resistance to deformation and is intended to withstand higher pressures.
This makes it particularly useful for turbocharged applications where accurate vacuum and pressure signals are essential.
4mm Inner Diameter
The hose features a nominal 4mm inner diameter.
This size is suitable for compatible vacuum fittings, boost control solenoids, and pressure reference ports designed for 4mm hose connections.
A properly sized hose helps maintain a secure connection and reduces the likelihood of leaks.
Always verify the fitting's outside diameter before installation.
9mm Outer Diameter
Turbosmart specifies a 9mm outside diameter for its 4mm reinforced vacuum hose.
The additional wall thickness accommodates the reinforced construction while providing durability for automotive applications.
The approximately 2.5mm wall thickness is calculated from the published inner and outer diameters.
3-Meter Continuous Length
The TS-HVR0403-BK is supplied in a 3-meter length.
This is equivalent to approximately 9.84 feet of hose.
The length allows installers to cut individual sections according to their application.
Common uses include:
Short wastegate pressure reference connections.
Boost control solenoid plumbing.
Blow-off valve vacuum reference lines.
Intake manifold pressure signal connections.
Custom turbocharger vacuum line routing.
Replacement of deteriorated factory vacuum hoses.
Measure each required section before cutting to minimize waste and ensure proper routing.
Turbocharger Boost Control Applications
Electronic and manual boost control systems rely on accurate pressure signals.
The TS-HVR0403-BK can be used with compatible boost control solenoids and pressure reference fittings requiring 4mm hose.
Its reinforced construction is beneficial where pressure changes occur repeatedly during turbocharger operation.
Correct hose sizing and secure connections are essential for maintaining consistent boost control.
External Wastegate Applications
Pneumatic external wastegates use pressure reference lines to control actuator operation.
The Turbosmart reinforced vacuum hose can be used with compatible external wastegate pressure ports and fittings.
A damaged or leaking reference line can affect wastegate response and boost control.
Using properly sized reinforced hose helps maintain a dependable pressure connection.
Internal Wastegate Actuator Applications
Internal wastegate actuators also rely on pressure reference signals.
The TS-HVR0403-BK provides a reinforced hose option for compatible actuator connections requiring a 4mm inside diameter.
The hose must be properly routed and secured to prevent contact with excessive heat or moving components.
Blow-Off Valve Vacuum Reference Applications
Many pneumatic blow-off valves require a connection to the intake manifold to monitor pressure changes.
The TS-HVR0403-BK can provide this reference connection when the valve and manifold fittings are compatible with 4mm hose.
A properly sealed reference line helps the blow-off valve respond consistently during throttle transitions.

Important Application Considerations
Although the hose is designed for demanding automotive vacuum and pressure reference applications, it should not be used indiscriminately for every fluid or pressure system.
Before installation, verify suitability for the intended operating conditions.
Do not substitute this hose for dedicated fuel, brake, hydraulic, or high-pressure oil lines.
Turbosmart's public product description does not specify an exact maximum working pressure or temperature rating for this part number. Those limits should be confirmed with the manufacturer when critical to the application.

Cut the New Hose: Use a sharp hose cutter to create a clean, square end.
Avoid Crushing the Hose: Ensure the hose remains round and unobstructed after cutting.
Install the First Connection: Push the hose fully onto the appropriate fitting.
Route the Hose: Maintain smooth bends without kinks or excessive tension.
Connect the Opposite End: Ensure the hose is fully seated on the corresponding fitting.
Secure the Connections: Use suitable retaining clamps where required.
Keep Clear of Exhaust Components: Avoid direct contact with turbocharger housings, exhaust manifolds, and downpipes.
Protect Against Abrasion: Prevent rubbing against sharp edges or moving engine components.
Verify Pressure Reference Routing: Confirm that the hose connects to the correct pressure source and component port.
Inspect for Leaks: Perform an appropriate vacuum or pressure test.
Verify Component Operation: Confirm proper boost controller, wastegate, or blow-off valve response.
