INSTALLATION GUIDE
• Metal flexible hoses should be bent and used only to the radius and lateral movement specified in their guidelines to prevent
fatigue and failure.
• Twisting of metal flexible hoses should be avoided while installing and using as well.
• For guidance on dynamic movement, please contact us.
NOTES
• Best-fit product for Water handling and budget optimization.
• For Oil and Gas applications, it is recommended to switch to models NK-VN2500 or NK-VN2600.
