SUMMARY

Bristan 40.2251.450 Neoperl M24 5 lpm Coin-Slot Flow Limiter (Orange)

The Bristan 40.2251.450 is a Neoperl M24 male-threaded flow limiter designed to reduce water flow to approximately 5 litres per minute. It helps lower water consumption and is suitable for many taps and showers that accept M24 inlet flow regulators.

Function

This coin-slot flow limiter restricts flow rate inside the tap or shower inlet tails (or outlet tails depending on installation) to 5 lpm, helping conserve water while maintaining usable pressure. It is compatible with low-pressure systems down to around 0.2 bar. :contentReference[oaicite:1]{index=1}

Typical Use & Compatibility

The limiter fits taps or showers that accept a male M24 threaded flow-limiter insert. It is often used as a retrofit or replacement part in basin mixers or shower sets that originally accept or allow M24-thread limiting inserts. :contentReference[oaicite:2]{index=2}

Selection and Verification

Before ordering, verify your tap or shower spout/inlet tail has a male M24 thread and accommodates a flow-limiter insert. Flow regulators are not universal by appearance — correct thread size and internal geometry must match to avoid leaks or faulty operation.

When to Install or Replace

Install or replace this flow limiter when reducing water usage is desired, flow rate is too high for low-pressure systems, or when the existing flow restrictor is damaged or missing. Fitting this limiter can save water and reduce flow without replacing the entire faucet or shower unit.
