Ace Glass 8765-27 Firestone Vacuum Manifold, 4-Port, with UHDPE Plug Handle Material

Vacuum/gas manifold with a Firestone rapid purge valve at one end and 0-5 mm high vacuum, Easy-Action PTFE stopcock ports with 3/8-inch O.D. Swagelok tubing connections. Each connection has an O-Ring groove (O-Rings supplied) for use with #11 Ace-Thred. Valve eliminates the need for a second tube. Simply connect one 10 mm O.D. arm to vacuum, the other to a gas source, and by half turn of the stopcock plug you can alternate between vacuum and gas. Shut-off float on gas side of valve prevents pressure buildup when system is purged. Plugs are PTFE with UHDPE (Ultra High Density Polyethylene).

Valve designed by Dr. Raymond Firestone.
