Now our 1/2" Full Bore fitting is available with 1/2" Female NPT threads! The OD of the barb is .625" and typical silicone or vinyl tubing will press right over it. Every other 1/2" barb fitting I was able to find only had a .375 to .400 ID resulting at a restriction at your hose connection (including our standard 1/2" hose barb). This is especially helpful on the inlet side of a March pump to help reduce pump cavitation. Frustrated with the other options on the market, I had these barbs made just for the home brewing market.

Side by side comparison between a standard 1/2" hose barb fitting on the left and our 1/2" Full Bore High Flow fitting on the right. Shown with Male threads, but this version has female NPT threads!

Looking down the bores of each fitting, you can see how much larger the ID of the Full Bore fitting is.

Made from 304 stainless steel and highly polished.

All images show the male version, this part is for the female version.  This part will be available 1/8/11
