Review on Tailonz Pneumatic Cylinder Connector - MAL25X150 by Vincent Burton

I was impressed with the metalwork and durability, but unfortunately an air leak around the tappet rendered the cylinder unusable. My guess is that the seal doesn't fit, or the stem doesn't stop and hits the seal in the fully extended position, damaging the seal (the surface of the stem was smooth, so I suspect no leaks due to the roughness of the stem surface). If the manufacturer fixes this leakage problem (which other customers complain about), this product could become a very good product. I was able to disassemble the cylinder and try to fix it myself, but didn't have much time and sent it back the next day.
