42 Draft Designs - Universal Water Temperature Sender Adapter

42 Draft Designs

This product is unfortunately no longer available.


Use this universal water temp adaptor to install a water temp gauge and sender in your VW or Audi. The 42DD adaptor splices into the factory radiator hose allowing the installation of an 1/8" NPT water temperature sender. The adaptor is precision machined from 6061 aluminum for a perfect, leak free fit. Included with the adaptor are two OEM clamps and a stainless steel ground screw.

Unlike similar adaptors on the market, the 42DD adaptor is exactly the same size and shape as all late model factory fittings. This eliminates all "what size do I need" guesswork while also preventing coolant flow restrictions. Like the factory fittings, the inlet of this adaptor is tapered internally to smooth coolant flow. Additionally, the back of the hose barb is rounded to allow removal of this adaptor at any time. Sharp hose barbs on tubing this large are essentially permanent.

Please confirm the thread pitch of your aftermarket sender before ordering. This adaptor is designed to use an 1/8" NPT aftermarket sending unit.
