Review on YSTOOL Cylinder Professional Compression Automotive Tools & Equipment by Steven Hanson

Revainrating 3 out of 5

Not the best tools for diagnostics, testing and measuring

A non-return valve or ball valve is required so that the air hose can be removed without pressure loss. Totally useless.

Pros
  • Made of aluminum and rubber, universal straight/angled connectors do not need to be screwed into spark plug wells and will fit almost all petrol engines as well as M14 aluminum extensions. The pole can be mounted on the long/short end of the hose (41-3/4"; 11-1/2") for greater clearance and easier operation. Adapter dimensions: M14*1.25, M18*1.5, M10*1, M12*1.25. High quality and deep thread makes the fittings bite better, does not slip and is durable.
Cons
  • disappears
