About this part
- Drain-line flow restrictor for RO water purifiers
- Marked FLOW 450, with a flow arrow
- Push-fit ends; sellers list it for 1/4 inch pipe
A flow restrictor for RO water purifiers, marked FLOW 450 with an arrow. Our supplier lists it as Shitong ST027. It is a white inline body with a push-fit socket at each end. Sellers of the Shitong 450 list it for 1/4 inch pipe and a flow of 450 ml a minute.
It sits on the drain (reject) line of the RO membrane. By holding back the drain water, it keeps pressure on the membrane so it can make purified water. Replace it when water runs to the drain much faster than before, the drain flow stops, or it is cracked.
Check before you order: the number printed on your old restrictor should match, since it must suit your membrane. Fit it with the arrow pointing the way the water flows.
A replacement part kept in stock in Bangalore, so a repair does not wait on a courier from another state.

FR 450 Shitong ST027 — questions we get asked
How much is the FR 450 Shitong ST027?
₹125, and that is what you pay — the amount is restated before you confirm and nobody re-prices it after opening the appliance. Fitting, if you want it, is quoted separately and agreed first.
Will it fit my water purifier?
Filter and membrane fitment depends on the purifier model and its housing size, not just the brand. Send us the model number and we will confirm the right consumable. WhatsApp a photo of the appliance and of the failed part, and we will confirm the match before you pay for anything.
Do I have to book a technician to buy it?
No — buy the spare part on its own if you are confident fitting it. If you would rather not, book a water purifier visit and the technician arrives with it, so the repair finishes in one trip.
How soon can I have it in Bangalore?
It is in stock in Bengaluru. Parts we hold locally usually reach a job the same day, and most repairs booked against them close within 12 hours across the city.
Can I get a GST invoice?
Yes. This part invoices under HSN 84219900, and a GST invoice is raised for the order — which is what a technician or a dealer buying for a workshop needs.
