As part of our continued efforts to expand our range of pressure sensor accessories, we have now released a brass bi-conical universal vacuum adaptor. This can be used to allow the WPS and FirstLook Sensor hoses to be connected to various sizes of smaller vacuum hoses within an engine bay. The adaptor fits vacuum tubes with internal diameters ranging from approximately 8.5 mm or 5/16", to 2.8 mm or 1/8".
