🔧 C&D CD3813 Brass Valve Core Tool by C and D Valve Co Review

I like the fact that it's made of brass and has internal storage for spare valves. Good value for money. I would recommend this seller.

Highly recommend this product. Very well made. Very durable materials used for production. Would highly recommend this product to all HVAC&R professionals.

Well done. I've had similar ones in the past but they were losing space so I just got two of these. It would be nice if they had a loop on the lid so you could attach a string and hang it in the store. Then maybe I wouldn't lose her so often.

Both tool and cores are of good quality. You should not skimp on valve cores, as expensive refrigerant can leak. This is a brand that consistently makes high quality parts to tight tolerances. Unlike some other brands, I've never had a problem with C&D parts. They are worth the extra cost.

There were valve core leaks in the central air conditioning and the system was already dead. I used this tool to replace all three on my system. It has three teflon sealed valve cores that worked great. After removing the old one and installing the new one, I took a deep vacuum and recharged it and found no leaks. Great valves, great tool!
