6mm Quick Connect Ball Valve Plastic in Sri Lanka (Inline Water Shut-Off)
Make filter changes and maintenance easier with this essential 6mm Plastic Ball Valve. Designed for Reverse Osmosis (RO) systems and water purifiers common in Sri Lanka, this valve allows you to manually turn off the water flow between two sections of tubing without needing tools.
It features a simple “Quarter-Turn” Blue Handle—just twist it 90 degrees to stop the flow instantly. This is a “must-have” safety part to install before your filter housings or UV stages.
Key Features:
-
Leak-Proof Design: Uses advanced “Push-Fit” technology with double O-rings to ensure a secure seal.
-
Easy Operation: Smooth ON/OFF handle that is easy to turn even in tight spaces.
-
Food Safe: Made from high-quality POM/PP plastic that is odorless and non-toxic, preserving the taste of your water.
-
Universal Fit: Works with any standard 6mm (1/4 inch) RO water tube (white flexible pipe).
Common Uses:
-
Maintenance Switch: Install before a filter stage so you can change cartridges without turning off the main water supply.
-
Flow Control: Reduce or stop flow to specific outlets (e.g., a coffee machine line).
-
Emergency Stop: Acts as a quick safety valve if a leak occurs further down the line.
