Anyone know if there is a shut off valve for 5/16 tubing? I found a clamp shut off used for water lines in poultry feeders. I'm not sure if these will withstand vacuum or not.

There a couple approaches with brass fittings, what are you trying to accomplish?

I plan to tap the birch trees in my bush this year. Instead of running all new tubing I am going to dump right into the mainline that I have run for my maples. That being said I am going to be able to just put shut offs on most of my branch lines which are 1/2" to shut off the maple lines. I have some of the 4-way fittings tying some 5/16 lines to my mainline though and in several instances I am only using 2 of the inlet and have the other 2 capped off with a piece of 5/16 tubing between them. My hope is to utilize the 4-way fittings for both birch and maple and install a shut off on them so when its time to switch to birch i simply shut off the maple lines and tap my birch and vice versa...

Here's a cheap one, http://www.northernbrewer.com/shop/5-16-in-line-valve.html but with no barbs you couldn't have an tension pulling on it. You can defintely find brass adapters to use brass valves, but it'll be pricey.

Cheap valves likely won't hold vacuum.

Found some with barbed ends at this place $2.50 each. For that I'll try them.http://www.bassequipment.com/Waterers/The+Borak+Flexible+Tube+System/default.aspx thx for replies
I thought there might be something made just for syrup line. I guess not to many uses for one...
