Durable inline pressure reducer for water purifiers and inlet piping Purpose built: an inline valve designed to feed water purifiers and related inlet lines with a stable, safe pressure. Compatible with most water purifiers, faucets and other water equipment. Compatibility and fit: compact inline design that fits standard purifier inlets and hoses for easy retrofitting. How it works: reduces the inlet pressure to a safe level for 3way ball valves and purifier inlets; can be installed in series with the purifier inlet pipe. Performance benefits: helps maintain steady flow when inlet pressure is low, and mitigates pressure fluctuations at higher supply to protect filtration and downstream equipment. Easy adjustment: adjustable without special tools; turn counterclockwise to decrease pressure. Preset safe pressure is 2–2.5 kg and can be used directly. Build and durability: constructed from durable materials suitable for long term use in water systems. Use scenarios: Install at the purifier inlet under the sink to ensure reliable filtration performance. Inline with a kitchen faucet filtration line to stabilize pressure for better filtration. In office or cafe water filtration setups to maintain consistent pressure for multiple devices.
