Hose-to-shower connections
MC1900 includes a soft washer. Compare lugged MC1901 where regular removal for cleaning is needed.
The Installation Position Determines the Format
Shower brands and manufacturers can start with the available position in the waterway. Washer-type, thin, build-in and removable restrictors suit different assemblies; target flow alone does not make them interchangeable.
Start with the Task
Inside handles and overhead showers
Review MB1400 for tail connectors and handles; compare MA1800 or MB1500 by threaded or internal inlet position.
Insufficient low-pressure flow
Compare removable H9 models for upper-floor or solar-fed supplies. Removal can eliminate the restriction but does not increase supply pressure.
What to Check Before Choosing
01
Locate the component
Identify a hose joint, G1/2 overhead inlet or internal handle or pipe cavity.
02
Define removal needs
Compare MC1901 for regular removal and H9 where the restriction needs to be removable in low-pressure use.
03
Check the fit
Check connection, cavity fit and depth. Select MB1400 or MB1500 against the corresponding dimensions.
04
Assess the complete shower
At the intended supply pressure, check the sample assembly for spray performance and target flow.
Choose a Model for the Application
MC1900 / MC1901 | Hose Connections
MC1900 includes a soft washer for connection-point restriction. MC1901 adds a lug for positions requiring removal for cleaning or replacement.

MA1800 | G1/2 Overhead Inlets
Primarily for threaded overhead-shower inlets. Compare MA1900 for larger waterways and MA0900–MA1200 by size for compact hand showers.
View Product and Specifications →
MB1400 / MB1500 | Internal Installation
MB1400 primarily serves tail connectors and handles; MB1500 serves overhead inlets and shower pipes. Compare MB1600 and MB1640 for other internal pipe sizes.

HL1814H9 / HL1815H9 | Removable Restriction
For shower inlets needing removable restriction in 14mm or 15mm waterways respectively. Flow after removal still depends on the supply and complete shower.
View Product and Specifications →Check Spray Performance at the Intended Pressure
Confirm target flow together with supply pressure, internal waterways and spray-hole performance.
Use the flow chart for the specific MC model as a reference; do not apply it to MA, MB or H9 models.
Ordering and Customization
Start with an Installation Drawing
Send the connection or cavity drawing, supply pressure and target flow, then confirm model, quantity, flow markings and packaging. A photo can start the discussion if no model is selected.
Selection Questions
Which option is easier to remove at a hose joint?
Compare lugged MC1901 for cleaning access. MC1900 serves conventional connection-point restriction.
Should an overhead shower use MA1800 or MB1500?
MA1800 serves G1/2 threaded inlets; MB1500 serves internal installation positions. Choose by the actual waterway structure.
Does H9 solve low supply pressure?
H9 allows removal of the restriction but does not boost pressure. Check low-pressure performance with the complete shower sample.
