1/2″ MPT x 3/8″ Stainless Steel Hose Barb.
The male pipe thread will fit into all 1/2″ ball valves and fittings that have female threads. Use these to attach a Hose Barb to the outside end of your Ball Valve, very handy for draining brew kettles or mash tuns. Barb fits 3/8″ high temp silicone hose or 3/8″ vinyl siphon hose. Please Note: Vinyl siphon hose is not for use with hot wort, silicone hose has a much higher temperature resistance. Use Teflon thread sealing tape to prevent leaks and stuck threads.
