The 10 Most Common Questions About ZoomLock® Flame-Free Refrigerant Fittings

The 10 Most Common Questions About ZoomLock® Flame-Free Refrigerant Fittings - ZoomLock Flame-Free Refrigerant Fittings - Parker SporlanWith the introduction of ZoomLock Flame-Free Refrigerant Fittings we have come across many people in the HVACR industry that have questions about using it. So here we answer the 10 most common questions about using ZoomLock. 

Q1: What tools are compatible with ZoomLock jaws?

Three different jaw configurations are available to ensure a broad range of compatibility to use with your preferred tool. Options include:

Klauke: 19 kN Crimping Tool MAP2L19

RIDGID Compact Press Tool Models: RP 240, RP 241, RP 200, RP 210, RP 100 

Milwaukee: M12™ FORCE LOGIC™ Press Tool 2473-20

Q2: Can ZoomLock be crimped in the same location as Viega ProPress fittings?

No. ZoomLock is different than other industry crimping technology. The jaw must align between the O-ring and outer flange. Grooves in the jaws make it easy to align. The fittings will leak if you do not crimp as stated in the ZoomLock installation instructions. Proper crimping alignment is also illustrated in the photo above.

Q3: How many ZoomLock crimps can you complete on a full battery charge?

On average you can achieve 100-150 crimps per charge depending on the size fittings being crimped. Each Klauke Toolkit comes with 2 Makita Lithium-ion 2.0 Ah 18V batteries (BL1820B) and a rapid charge charging system. To prevent any downtime, it is recommended that you have both batteries charged before going to the job site and to have one charging while the other is in use.

Q4: When pushing the ZoomLock fitting onto the copper tube, how do I know the correct insertion depth?

The 10 Most Common Questions About ZoomLock® Flame-Free Refrigerant Fittings - ZoomLock Minimum Insertion Depth Chart - Parker SporlanUse the depth gauge provided or the minimum insertion depth chart to determine the correct insertion depth. Mark the tubing with a permanent marker to indicate proper insertion depth on every tube.

Q5: Do you have a solution for crimping onto flared tubing like that coming out of the condenser and evaporator on residential units?

No, we do not have a specific product designed to crimp over the flared tubing. However, if there is at least 2 inches of straight copper tubing after the flared end and is accessible with the jaws, we suggest that you cut the flared end off and crimp directly to the tube.

Q6: Can you use ZoomLock to crimp to aluminum, steel, or stainless steel?

No, ZoomLock is specifically designed for copper to copper connections. Connecting to dissimilar metals can cause formicary corrosion issues that could cause a failure.

Q7: Is ZoomLock approved by state and city building codes?

ZoomLock has been approved by UL-207, ASHRAE 15, International Code Council – Evaluation Service (ICC-ES), International Mechanical Code (IMC), Universal Mechanical Code (UMC), and International Residential Code (IRC). These approvals are all that is needed in most areas. Please contact your local building inspector with questions prior to install.

Q8: What material is the O-ring made of?

The o-ring is a highly engineered HNBR Parker o-ring that has been used in HVAC applications by OEMs and suppliers for many years with no issues.

Q9: Can you show an example of a “good” copper tube surface after sanding?

Figure 2 is an example of a tube with a bad scratch that requires proper tube preparation. It is very important to follow the deburring, sanding and inspection steps 4 to 8 in the installation instructions.

Q10: What is the #1 cause of leaky fittings?

Skipping the installation instructions will cause the tube to leak. It is very important to use the scouring pad and deburring tool included in the kit. Refrigerant gas at the maximum rated 700 psi pressure is more likely to leak than water at a much lower pressure, therefore, following the tube preparation instructions is very important. See the video below for proper tube preparation.
