How we calculate scores →About this gear
ADV Diaphragm JJ is the replacement diaphragm listed for the JJ automatic diluent valve, under part number 301628001110001. It is an internal service component, not a complete ADV assembly.
Consider before buying
The product listing does not establish a service interval, material specification or compatibility with every revision of the valve. A matching appearance is insufficient when choosing a breathing-system component.
Our take
Purchase it as part of the correct JJ service procedure and have the valve’s function checked after the work. A different diaphragm is not a supported alternative unless JJ explicitly specifies it for the same assembly.
