Ace Glass 8765-29 4-Port PTFE Vacuum Manifold, Firestone

Features:

• Vacuum/gas manifold with a Firestone rapid purge valve at one end and 0-5mm 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 10mm 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 the gas side of the valve prevents pressure buildup when the system is purged.
• Plugs are PTFE with PTFE handles with FETFE O-Rings.
