Flow Restrictor Series
The MC family provides washer-type flow restriction in several outside diameters, including a model with a lug. Start with the installation format, then compare dimensions, flow requirements, and service access.
The family specification sheets list POM / silicone materials, an operating temperature of 0–55°C, and OEM packaging. Review the actual assembly conditions before final selection.
For connections between hand showers and shower hoses or risers, and for small spray-gun inlets. Also used with braided hoses and overhead showers; the soft washer simplifies installation at the connection.

MC1900 can restrict inlet flow at compatible hand-shower and hose connections, overhead showers, braided-hose connectors and handheld bidet sprayers. Check the seating surface, compression and target flow for each connection.

Check the seat, compression arrangement, and sealing requirements. Outside diameter alone does not establish a thread size or confirm that the component can replace an existing seal.
Include an assembly drawing or installation-area photo with available space, required functions, and operating pressure. After the structural review, validate the finished assembly with samples.
Both specification sheets list a 19 mm outside diameter. MC1901 is additionally identified as having a lug. Check the seat and removal clearance before choosing or substituting a model.
Model numbers alone do not establish different applications. Select by function and format first, then check dimensions, flow configuration, and assembly conditions.
Use the range as a specification reference. Define the model, target flow, test pressure, and tolerance for the delivered configuration.
Available dimensional documents are listed by model, with flow charts where supplied. Include any additional test, material, or destination-market document requirements in the inquiry.
Outside diameter or appearance is not enough. Check installation position, compression and seal structure, thickness and the complete water path.
Share the finished product, installation position and drawing, required functions, target flow and pressure, expected quantity, and destination market. We will help review models, samples, and documentation requirements.
