What should I do to ensure that a fitting doesn’t leak after pressing?

• Verify the tubing does not have scratches, incise marks and dents prior to tube cutting. Be careful when using a knife to cut off plastic shipping caps or insulation off copper tubes.
• Take time to cut the tubing properly using a tubing cutter. Rushing through the cutting process may cause dents and oval tubing, which can create leaks.
• Verify proper deburring and sanding/cleaning of tube surface per instructions.
• Verify proper tube insertion depth using the provided depth gauge. One gauge is provided with the tool kit or can be ordered separately. You can also refer to the “minimum insertion depth” table in the RLS installation instructions.
• Verify the proper crimp diameter using the provided crimp gauge.
• Verify the correct jaw is installed for the fitting you are trying to press.
• If the jaw is sticking during the press, try applying a light coating of spray lubricant such as WD-40 directly to the jaws.
• Let the jaw and tool do the work. If the fitting is in a hard to reach place, it is important to let the tool body move freely.
• Avoid applying any sort of pulling or twisting of the tool during the pressing process.
