Condition: Used
This stainless steel DN16KF to DN40KF vacuum flange reducer adapter has been inspected and appears to be in good used condition. It was pulled from a working vacuum system where it was in active use. The machined flange faces and bore are intact with no visible damage. Some light surface marks and minor scuffing are visible on the body, consistent with normal service use. No cracks, deformation, or weld defects are apparent. Please view our photo set and contact us if you have any questions.
