How to install repair coupler for pipe repairing?

Installation Steps

1 First Clean Up Any Foreign Impurities Near The Pipe Repair Leak Point.

2 Remove The Screws Of The Double Bands Repair Clamp And Open It.

3Take Out The Rubber Sleeve Inside And Snap It Onto The Leak Point (Note That The Location Of The Leak Point And The Location Of The Rubber Sleeve Joint Should Be Staggered As Far As Possible).

4 Attach The Repair Housing To The Sealing Sleeve (Avoid The Middle Of The Repair Housing Where The Rubber Sleeve Is Attached And Place It As Close To The Top Of The Screw As Possible) And Pre-Tighten It On Both Sides With A Spanner, Using A Rubber Hammer To Hit The Upper Or Lower Part Of The Repair Housing.

5 Refer To The Pre-Tightening Force And Pressure Requirements Corresponding To Each Size, And After Pre-Tightening On Both Sides, You Can Infuse And Press Normally After Installation.
