How we calculate scores →About this gear
This R217C manual-add block is the 0.0035-inch-orifice version, part 48600745. Its exact official listing specifies regulator connectors on the inboard inlets and a diluent/oxygen/diluent arrangement.
Consider before buying
R217C alone is not enough to identify the assembly: the official parts list also contains a 0.0030-inch version under a different part number. The orifice is a system-design choice, not a buyer-selectable performance upgrade based on appearance.
Our take
Order by the complete part number and approved rebreather configuration. We would not substitute another R217C variant or a no-orifice block without manufacturer confirmation. This is a replacement gas-system component, not a complete regulator.
