C&D CD5050 Small Thumb Screw Core Depressor / Flow Control Valve

The media could not be loaded. Many negative reviews about manual core depression tools likely result from improper usage. When used correctly, these tools do not blow out O-rings; they seal effectively. Issues with incorrect pressures are probably due to using incompatible hoses. It is crucial to use the correct hose, one without a core and equipped with a valve, and utilize this tool as your core depressor. Follow my video instructions for optimal results. Once you experience their performance, you’ll see they work amazingly well, and you won’t want to use anything else.

Great Product for a Great Price!

Nice and small, no complaints.

I have had no issues the past year using this tool. Only had 1 issue and it was user error.I have not encountered any leaking on them. I would not use them in a vacuum

Me han ayudado mucho en mi trabajo, ya no hay manchas de aceite al momento de conectar las mangueras de mi manómetro.

First time I used them (I ordered two) I couldn't read the right pressure I found out. It showed the system was low, when I went to add some and my suction gauge when up to 100 I turned off the bottle and it stayed at 100. I took them off and hooked my gauges back up and the system was fine. I thought somehow user error so I tried them again and the junky rubber seals started to peal apart! I strongly do not recommend. I with I could send them back for a refund!

Worked well until it didn't. Tried new o rings worked for a short period then back to spraying refrigerant out the thumbscrew portion. I've used others that are this same style and never had an issue so maybe I got a dud, but I've used better build quality in the passed. I do prefer this style of fitting tho. 50 / 50 on my recommendation

Very good
