LET-LOK® fittings installations instructions and guidlines

 

 

 

 

Ham-Let LET-LOK® fittings are the high-quality solution for various installations.

To maximize their performance, we provide customers with full time support and assistance.

 

 

 

 

 

 

 

 

 

 

Here are some tips that will help you to avoid future leaks

and decrease system down time:

 

 

  1. Scratches on the tube surface can cause leaks. Avoid dragging the tube out of the box and on the floor as it damages the surface.
  2. While preparing the tube for cutting, don’t hold it directly on the vise - it will damage the tube O.D.
  3. Cut the tube while it rests on a surface vertical to the floor.
  4. Cutting – while you can cut the tube using any method you find want, we recommend using the Ham-Let tube cutter. The Ham-Let tube cutter minimizes damage, providing a finer surface.

 

 

  1. Cleaning – before inserting the tube into the LET-LOK®, make sure you clean the tube edges properly. We recommend using the Ham-Let deburring tool.
  2. Please make sure the ferrules are located in the fitting in the proper order. See below:

 

  1. Prior inserting the tube, please release the nut in order to assure smoother insertion
  2. While inserting the tubing into the LET-LOK® fitting, check that the tube rests firmly on the fitting shoulder
  3. Before closing the LET-LOK® mechanism by 1-1/4 or 3/4 turn (depending on the tube O.D), make sure to reach a finger tight position and mark a reference point on the nut, tube and body
  4. While closing the LET-LOK® it is important to use a proper wrench that fits the size of the body and the nut to avoid the wrench slipping or damaging the fitting.
  5. In order to make sure the installation is proper, we recommend using our indication accessories:


 

Product quality – is our TOP priority.

Please work according to our installation and

working pressure guidelines and specifications.
