AISIN vacuum switching valve VST-006

What matters most

For someone replacing a vacuum switching valve by part number, the AISIN VST-006 is presented as a direct-fit, OE-grade replacement for 25860-74050, 25860-74160 and 90910-12080. Its blue housing and black frame are important identification details, not just a colour choice: the listing says this valve is application-specific and asks buyers to match the colour of the old part.

The design uses resin for a compact, lightweight build, while fluorine rubber is described as heat- and chemical-resistant. Magnetic-field analysis simulation and bench evaluation are also cited in its development. Those details describe the design approach, but they don’t establish fitment for every vehicle that uses a related-looking valve.

It may suit you if you’re replacing one of the listed references and the part you’re removing has the matching blue colour. A practical first step is to compare the old valve and the VST-006 side by side before installation. Keep in mind that the product information specifically warns that colour matters, so a matching part number alone should not replace that check.

How to use it

This is a replacement component, rather than a universal accessory. The listed reference numbers give you a starting point for identifying the part, while the application-specific note makes matching the existing valve’s colour another part of the decision. If you’re not handling the original part yourself, get its reference number and colour from someone who can confirm them before choosing.

The description does not provide installation steps, vehicle applications or additional fitment details. That makes this a more focused choice than buying a generic valve based on appearance, but it also means you’ll need to establish that the references and colour match your application. It may not be the right fit if you can’t identify the valve being replaced or its colour differs from the blue housing shown.

Practical tips

Check the old part’s printed reference, if available, against 25860-74050, 25860-74160 and 90910-12080. Then compare its colour with the VST-006’s blue housing and black frame. A quick visual comparison can help catch a mismatch before you begin replacing anything. Don’t assume that similar shape or a related part number is enough when the product information calls out colour as application-specific.

The material claims may matter in a warm or chemically exposed setting: the listing describes fluorine rubber as resistant to heat and chemicals, and the design as vibration-resistant. These are stated design properties, not a substitute for confirming the correct application. No care or cleaning instructions are provided, so there’s no basis here for recommending a particular cleaner or maintenance routine.

Before you decide

Which replacement numbers are listed? The VST-006 is listed as replacing 25860-74050, 25860-74160 and 90910-12080. Confirm that your original part corresponds to one of them.

What colour should the existing part be? The product has a blue housing and black frame. The description says to match the colour of the part being replaced.

What is it made from? The listing identifies resin for the lightweight, compact body and fluorine rubber for heat and chemical resistance. It does not provide further material or maintenance details.

For your situation

The VST-006 makes the most sense when its reference number and blue housing match the valve you’re replacing. If those details line up, its stated direct-fit, OE-grade positioning gives you a specific replacement to consider rather than a generic part chosen by looks alone. If the old valve is a different colour, or you can’t verify the reference, pause before ordering: the available information doesn’t confirm broader compatibility.
