Key Features & Benefits – boost pressure adapter for silicone hose M10x1.25
The boost pressure adapter for silicone hose M10x1.25 is a boost pressure adapter that creates a pressure takeoff point in the first silicone coupler after the turbo compressor outlet. It is designed to provide a pressure source without drilling or tapping the turbo housing.
The kit includes a CNC-machined steel barb fitting and a stainless steel nut, with a threaded body and sealing shoulder on the fitting. The hose connection suits 0.25" (6.35 mm) ID vacuum hose, and the thread is M10x1.25.
When is this useful?
It works well when you need a clean boost/vacuum pressure signal for a boost gauge, MAP reference, or another pressure-based accessory taken directly from the charge piping. It is practical in builds where modifying the compressor housing is not part of the plan.

Selection & installation tips
- Placement: choose a spot on the first silicone coupler after the compressor outlet and allow space for vacuum line routing.
- Vacuum line size: confirm your signal hose is 0.25" (6.35 mm) ID and match the clamp size to the hose OD.
- Sealing & tightening: install on a clean, undamaged surface and tighten the nut so the sealing shoulder seats evenly.
- Wall & bend area: avoid placing it on the tight bend radius or stressed sections where the hose can deform.
- Routing & support: secure the vacuum line and keep it away from heat and moving components to maintain a stable signal.
Before installation, verify the thread, vacuum line size, available clearance, and the intended routing, then compare them to the specifications above. Checking the silicone hose wall area and how the line will be supported helps keep the fit predictable in your piping layout.
