Key Features & Benefits – LLRacing 3 mm silicone vacuum hose
The LLRacing 3 mm silicone vacuum hose is a flexible, small-diameter hose for vacuum and pressure reference routing. The blue colour helps you track lines in multi-branch layouts, and it is easy to secure in place with simple retainers.
Made from 100% silicone, it works from -60°C to +260°C and is listed with a 0.3 to 0.9 MPa working pressure (3–9 bar). Typical uses include blow-off valve reference lines, pressure/vacuum sensors, turbo and EGR control lines, plus brake booster and HVAC vacuum circuits.
When is this useful?
It is useful when you need a reliable small hose for vacuum or reference signals in tight engine-bay spaces and your ports are sized for a 3 mm ID line.

Selection & installation tips
- Port fit: Measure port OD and confirm the 3 mm hose seats tightly.
- Retention: Secure the hose so it cannot slip off and create leaks.
- Routing: Avoid kinks and keep slack for engine movement.
- Heat clearance: Keep routing away from very hot parts such as exhaust manifolds and turbine areas.
- Length planning: With running-metre supply, leave extra length at joints and for future servicing.
Before installation, verify port sizing, routing space, and heat exposure, then match them to the technical specs above.
