clamps for 1" vacuum hose

Designed to fit between the vacuum pump and the upper cart shelf on the AF-0300-01 cart to prevent oil from being drawn into the vacuum line. Offset inlet and outlet permits installation as illustrated. All sizes of the trap are fitted with a 4mm Airfree® valve to allow the equalization of pressure when the pump is shut down while still having the line portion remain evacuated. Available in three sizes to permit installation with the listed pump sizes, arms on all sizes have 1" OD glass tubing. Requires two AF-0300-11 hose clamps for installation.
