adapter for water thermometer

It sounds like you’re referring to a Water Temperature Gauge Connector Tube made of aluminum, typically in blue or silver, used as an adapter clamp for radiator sensor installation with a 32 mm diameter.

Here’s a quick rundown of what it is and how it works:

• Purpose: Connects a water temperature gauge sensor to a radiator hose without cutting or damaging the hose.
• Material: Aluminum (lightweight, corrosion-resistant).
• Color: Often anodized blue or silver.
• Size: Fits radiator hoses of about 32 mm diameter.
• Function: Clamps around the radiator hose and has a threaded port or adapter where you can screw in a temperature sensor.

If you’re looking to buy or install one, make sure:

• The hose outer diameter matches 32 mm (check the actual size).
• The sensor fits the port on the adapter.
• The clamp is securely fastened to avoid leaks.
