Flow Restrictor Series

Detachable Flow Restrictors

HL1814H9 and HL1815H9 serve hand-shower and overhead-shower inlets in low-pressure supplies. The restrictor can be removed when more flow is needed; select the model for the 14mm or 15mm waterway.

01 / Two Flow Modes

HL1814H9 restricts flow with the inner core installed. Removing the core allows water to pass through the housing without this core’s restriction. Actual outlet flow still depends on the supply and complete shower assembly.

02 / Shower Inlet Applications

HL1814H9 can be fitted at a dimensionally compatible hand-shower or overhead-shower inlet. Check the actual waterway bore, seating depth and sealing position before selection.

03 / Low-Pressure Supply Flexibility

HL1814H9 allows the restrictor core to be removed when the available supply pressure leaves insufficient outlet flow. Evaluate the resulting flow with the finished shower under its intended operating conditions.

Installation and Sourcing Notes

Confirm the outside diameter against the actual cavity or bore dimension. The outside diameter does not directly equal the pipe size.

Check the installation thickness, retention structure, and sealing arrangement before placing an order.

Provide cavity dimensions, target flow and pressure, expected quantity, and destination market for accurate model selection and sample review.

Common Questions

Can I select a model by matching the outside diameter to the pipe size?

No. The outside diameter does not equal the pipe size. Check the actual cavity dimensions, thickness, and retention structure.

What information should I provide for sourcing?

Provide cavity dimensions, target flow and pressure, expected quantity, and destination market. We will review model options and sample requirements.

Does removable mean that the component boosts pressure?

Removable describes service access, not pressure boosting. Flow after removal still depends on the water supply and complete system.

What should be checked for future servicing?

Review service access, working clearance, seal condition and reinstallation method. Confirm the procedure for the finished assembly.

Can HL1814H9 and HL1815H9 be interchanged?

Similar names do not establish interchangeability. Check the dimensions, seals and retention structure of each model.
