The KVMB Series has a strong, chrome-finished brass body, resulting in a reduction of magnetic attraction and increased durability over time. This series meets requirements for MRI-conditional components used in conjunction with a magnetic resonance imager for Level 3 Tesla requirements. Clearly marked for hospital use, KVMB products have naval brass lower plugs with PTFE coating for great lubricity. Cleaned for oxygen service, oil-free (CGA G-4.1).
