Choose this ZM-profile kit for ZoomLock MAX. NOT for RLS or original ZoomLock fittings.
Before you buy: original ZoomLock is NOT ZoomLock MAX
Identify the refrigerant PRESS FITTING brand and product series—not just the copper tube brand. Read the fitting and packaging markings, then check the part number and tube outside diameter. The word “ZoomLock” alone is not enough to select a jaw profile.
| Fitting brand / series on your job |
iCrimp model to consider |
Check before ordering |
| RLS / Rapid Locking System |
IWS-0625RCF — RLS profile |
8 jaw sizes: 1/4, 5/16, 3/8, 1/2, 5/8, 3/4, 7/8 and 1 in. Not the ZoomLock MAX profile. |
| Original / legacy ZoomLock (not MAX) |
RLS-profile selection route: IWS-0625RCF, after part-number confirmation |
Original RLS-made ZoomLock fittings belong to the RLS family. Check the RLS cross-reference and send the exact fitting part number for confirmation. Do not select IWS-0628ZMCF simply because “ZoomLock” appears on the box. |
| Parker / Sporlan ZoomLock MAX |
IWS-0628ZMCF — ZM profile |
7 jaw sizes: 1/4, 3/8, 1/2, 5/8, 3/4, 7/8 and 1-1/8 in. Not the original ZoomLock / RLS profile. |
| Conex Bänninger >B< MaxiPro |
IWS-0628ZMCF — check the exact series |
Listed in the IWISS ZM-model application specification. Confirm the regional fitting series, size and permitted tooling; do not assume every Conex product uses this profile. |
| ZoomLock PUSH |
Neither press-tool kit |
A push-to-connect system, not a press-jaw application. |
| Unmarked fitting / “ZoomLock” without a clear generation |
Confirm before buying |
Email clear fitting and packaging photos, part number, tube OD and country to sales@iwiss.com. |
Why the names cause confusion: RLS originally supplied fittings marketed as ZoomLock through Parker/Sporlan. RLS later sold under its own brand and announced the end of supply to Parker in August 2020. ZoomLock MAX is a distinct system; a shared historical brand name does not establish interchangeable jaws.
Use the manufacturer's current tooling requirements for the exact fitting. The model guidance above describes IWISS's intended application, not RLS, Parker or Conex Bänninger certification. Brand, series, jaw profile and size must all match.

IWS-0628ZMCF: a 7-size ACR copper tube press tool kit with ZM-profile jaws. This iCrimp kit brings manual and compatible impact-wrench drive options to refrigerant-line installation and service. Its jaw selection extends to 1-1/8 in. for technicians planning ACR copper tube connections with the specified fitting system.
Check the fitting system before ordering. IWISS specifies this ZM-jaw model for ZoomLock MAX and >B< MaxiPro copper refrigerant press fittings. Confirm the exact fitting series, tube specification, jaw size and permitted tool combination with the fitting supplier and iCrimp. This description does not claim third-party manufacturer approval, certification or warranty coverage.
Seven ZM-profile sizes for refrigerant line installation
-
Included jaw sizes: 1/4 in., 3/8 in., 1/2 in., 5/8 in., 3/4 in., 7/8 in., 1-1/8 in.
-
Two drive options: operate with the supplied wrench or a compatible impact wrench using the specified drive connection. Impact wrench, battery and charger are not included.
-
LED completion indication: helps identify the tool's completion condition. It is not a refrigerant leak detector and does not replace joint inspection or system testing.
-
Portable case: keeps the tool, jaws and drive accessories together for transport and storage.
-
Wire-cut jaws with electrophoretic coating: jaw manufacturing and finish as specified by IWISS.

Where this tool fits your workflow
For air-conditioning contractors and refrigeration installers, this kit offers a compact way to organize ZM-profile pressing equipment for line-set work, equipment connections and service repairs. Mini-split, heat-pump and refrigeration applications depend on the selected fittings, refrigerant and approved installation requirements. Press connections can eliminate the brazing flame at the press joint; they do not eliminate tube preparation, refrigerant recovery or commissioning procedures.
For restricted-access work, check the full space needed to fit the jaws, operate the drive and release the completed joint. A compact head alone does not establish the minimum working clearance.
Choose by fitting system and actual tube outside diameter
ACR jaw sizes refer to the specified tube outside diameter. Do not select by a water-pipe nominal size alone: 1/2 in. nominal copper water pipe and 1/2 in. OD refrigerant tubing are different sizes. Original RLS-made ZoomLock fittings follow the RLS-family identification route above. Do not interchange that profile with ZoomLock MAX or water-system press fittings.
Installation planning: prepare, mark, press and check
-
Confirm the complete system. Verify fitting series, refrigerant, tube material/temper/wall, OD and tool/jaw requirements. Isolate equipment and safely recover refrigerant before opening existing piping.
-
Prepare a sound tube end. Cut square, deburr inside and outside, keep debris out and clean the sealing area as the fitting manufacturer directs. Do not press over damaged, oval or deeply scratched tubing.
-
Inspect and mark. Check the fitting and seals, then mark the specified insertion depth. Seat the tube fully and retain a visible depth reference.
-
Align the correct jaws. Position the matching profile at the prescribed location. Use the drive settings and completion/release sequence in the IWS-0628ZMCF instructions; do not choose a universal torque or speed setting.
-
Inspect and commission. Check insertion, joint appearance and applicable gauge results. Perform the required pressure/leak tests and evacuation/decay checks before charging. Follow the equipment and fitting manufacturer's limits rather than a single generic pressure or vacuum target.
Professional refrigerant work requires appropriate training, PPE and the procedures applicable to the refrigerant, including flammability controls where relevant. Do not use oxygen to pressure-test refrigerant piping. This overview is a selection aid, not a replacement for the model-specific manual.
Questions before you buy
Does the kit include a depth gauge?
No. The current kit omits a depth gauge. Insertion depth must still be measured and marked using the fitting system's instructions and a suitable separate measuring or marking tool.
Can I use any cordless impact wrench?
No universal compatibility is claimed. Confirm the specific drive tool, socket suitability and operating settings with iCrimp before use. Manual operation is available with the supplied wrench.
Can I use this for ProPress water piping or PEX?
No water-system or PEX compatibility is claimed for these refrigerant jaws. Choose a tool and jaw configuration intended for that separate connection system.
Does ZM mean every ZoomLock or MaxiPro fitting is interchangeable?
No. Confirm the exact fitting generation and current permitted tool/jaw combination for each system. The IWISS application specification is not a claim of Parker or Conex Bänninger certification.
