Review on 🔧 Motive Products - 1100 European Master Cylinder Adapter: Convenient and Versatile Solution for European Car Maintenance by Michael Gupta

It fits and works well but the price is very high. (Maybe around $3 for parts.) Note that this cap fits both the master cylinder and coolant reservoir on a Volvo 240/740/940. In addition to bleeding the brakes as intended, you can also use it to make a coolant pressure gauge. I recommend removing the zip ties as soon as possible because one day when the vinyl tubing needs replacing you won't have to fight them to get the job done.
