• Reducing 50% of the water resistance,with twice the arc,the water flow impact pressure wave is scattered and disappeared by the curved surface.
• Meanwhile, it avoids directly striking the fitting and causing damage.
• The new U-profile tap elbow is ideal for hygiene-focused and water flow rate-optimized installations utilising various loop installation methods.
• Improved profile design allowing better flow rate.
• Easier and more adaptable installation.
• The swallow-tailed structure ensures zero leakage，excellent air-proof performance and safer connections.
• 12 anti-skid teeth and 36 occlusion points to ensure that the metal and plastic parts are inlaid tightly.
• Multiple techniques enhance the pressure resistance and flexibility.
• The check ring is designed to prevent overtwisting.
• Sand-blasting process with high precision.
• Full diameter, water flow increases by 200%.
• Three NBR seal rings to prevent leakage.
• High-quality brass of the valve spool, which makes it more durable.
Technical specification
• Applied for potable water pipeline system with hygienic and non-toxic features.
• High temperatures and high pressure resistant.
