Following the replacement of a master cylinder, I had to block an exit. Thanks to this pin, I was able to reassemble it quickly. Arrived quickly and well packaged I recommend .
I use this equipment to isolate a brake circuit in the event of a breakdown. vehicle immobilization is reduced
during off-road raids, brake hoses are sometimes broken. This plug isolates the defective part and allows you to continue.
exactly what I ordered, delivery was fast and packaging was meticulous
The plug screws seem to fit perfectly, I haven't pressurized the circuit yet, but the machining seems to be of good quality, I recommend MECATECHNIQUE.
correct packaging, on-time delivery and compliant product
nothing special. Brake circuit plugs.
perfect, just what I needed
very good seal with this product
Very good product I recommend it
Very practical, but the thread is not specified ...
solid, perfect for its purpose
very useful for ATE master cylinders equipped with several pressure sensor outlets. Is a copper gasket required?
Impeccable part, I haven't used it.
