no seal, doesn't seal at all, as soon as you open the valve you can hear the freon start flowing inside the fridge. Bought from another seller, works. Lesson Learned: 1. If you installed the puncture valve, don't pierce the hole yet, connect the charge hose and R194a canister first. Open the jar, put some pressure on r194a, close the jar. The pressure must remain in the hose for a long time, this is necessary to check the tightness of the system.2. If step 1 works tight, loosen the hose connection on the valve side just enough to release the pressure. This allows air to be removed from the hose.3. Now close the valve port and start turning the middle screw to pierce the hole.4. If in step 1 you already pierced the hole and found a leak in the system, close the connector, do not remove the valve, but leave it there forever. Find another location and install a new port.
