Valley View Vapors Welcome to Valley View Vapes - Your Home for Quality Inexpensive Tanks and Vaping Supplies Triple V 7 ml pyrex tank review (independent) A new tank vendor has begun distributing his version of a pyrex (borosilicate glass) tank. They are available in 4ml and 7ml sizes in clear ($13 and $15, respectfully) or frosted ($22 and $24) glass. These are grommet tanks, of which the grommets were custom made to fit this tank. They have a very tight seal. The easiest method to fill this particular tank, is to use a syringe, slid between the cartomizer and the grommet. The 7ml tanks use a 45mm cartomizer, the 4ml tanks use a 35mm carto. The tanks ship assembled with a single hole pre-punched cartomizer already installed. The vendor has genuine Boge cartos, available in both lengths with choice of resistance (2 or 3 ohm) . He also offers 5 packs for sale, and at your request will test (for correct resistance and for DOA cartos) and prepunch the cartos for $1. The 7ml tank measures 1"D x 1.5" L, the 4ml tank measures 1" x 1".

(I dislike the polycarbonate variety for multiple reasons.) I vape only with tanks and clearos. I would have preferred pyrex tanks, but the pyrex tanks available are at least double the price of a polypropylene tank, and I use many for my juices. Still, I keep my eyes open for all vendors offering pyrex, as I planned on getting one or two for my setup. When I saw Valley View Vapes was offering a pyrex tank at such an affordable price I decided to give them a try. For that low of a price, if they were crap I wouldn't be out that much money. If they turned out good, then I would be getting a steal. I ordered two clear glass 7 ml tanks. I also ordered extra grommets and 0 rings, and the blunt nose needle/bottle filling kit that the vendor sells. It was a slight challenge filling the tank with juice for me. Inserting the needle tends to push part of the grommet/0 ring farther into the tank with it. Once in filling position, I attached the bottle of premeasured juice to the needle and filled up the tank. (On hindsight, a pre-filled syringe with a Leur lock attachment would probably work better than the bottle.) Withdrawing the needle, the grommet remained in the "deformed" position in the tank. Luckily I had a dental tool available and was able to tease it back into position, good as new. The silicone is soft and could easily tear, but if you are careful you shouldn't have a problem. Pro's: For the money paid, I am very satisfied with my two tanks. I think they are nice looking. These tanks are never going to fall apart accidentally (tight fitting grommets and O rings) or accidentally fall off of my Silver Bullet (I am always mindful to be careful how I handle my DCT tanks on it.). At 4 and 7 ml size, they are pretty large capacity for a pyrex tank. Safe for use with polycarbonate-unfriendly juices. Con's: They are a slight pain to fill (aren't most tanks?). You must be mindful to be carefull with the fill needle not to damage the silicone seals. Extra sets of grommets and O rings and a dental tool are probably advised. The vendor also offers polycarbonate and polypropylene tanks.
