Duotight Push-In Fitting - 8 mm (5/16 in.) Tee - KL02387

Expensive but works great

UPDATE: After pay 250% more than it costs elsewhere, I had used it for a little over a month and one day the whole end just fell apart. That wasn't bad enough because it caused $20 worth of CO2 to empty from my 12 psi pressure system. I like Kegland products and I don't know why this Tee literally fell apart. I contacted the SELLER (KEG FACTORY ) and they did not have the courtesy to reply. Then I contacted Amazon and their great customer service refunded the cost. It was not the money, but the idea of paying way to much for a questionable item, then no response from the seller. And not just me. KEG FACTORY no longer lists their name with this product. No wonder. They have a -30% rating for the year and -56% for the last 30 days.
