D-Style Thread Flowmeter Knobs

The Tenacore 100531-03 is a D-style threaded flowmeter knob, a replacement or service component for gas-flow control assemblies in medical equipment. It is designed to thread into standard D-style flowmeter ports and is typically used in anesthesia delivery systems, ventilator circuits, or oxygen supply manifolds where manual flow adjustment is required. This knob is a direct replacement part for flowmeter assemblies that use D-style threaded connections. It is supplied as a standalone component for repair or maintenance of existing equipment.
