Product Information

Specifications

• Product Name: 1/2 & 3/4 Large PEX Crimp Tool
• Model Number: #23251
• Conforms to ASTM F 1807 standards

Product Usage Instructions

Connection Assembly

1. Cut the tube to provide a clean, straight end.
2. Slide the crimp ring over the tube end.
3. Insert the fitting into the tubing until the shoulder of the fitting contacts the tubing end.
4. Position the crimp ring 1/8 to 1/4 inches (3.2 to 6.4 mm) from the cut end of the tubing.
5. Place the opened jaws of the PEX Crimp Tool around the crimp ring.
6. Check the positioning of the crimp ring.
7. Compress the tool handles to complete the assembly.

Gauging Procedure

1. Determine the proper size of tubing: 3/8, 1/2, 3/4, or 1 inch.
2. Use the GO/NO-GO gauge to check if the crimping is done correctly.
3. Adjust handle distance if needed based on gauge results.

Adjustment Procedure

1. Close tool handles until pre-load is reached (jaws touch).
2. Measure the distance between dots on handle ends (8-1/4 – 8-3/4 is correct).
3. Adjust handle distance using eccentric lock screw and Allen wrench if needed.
4. Recheck handle distance after making adjustments.

Tool Maintenance

1. Check tool calibration daily, especially first and last crimps of the day.
2. Avoid exceeding specified handle distance during adjustments to prevent premature wear.
3. Lubricate linkages regularly for maximizing tool life.

FAQ (Frequently Asked Questions)

Q: How often should I check the tool calibration?
A: It is recommended to check the tool calibration daily, with a focus on the first and last crimps of the day.

Q: What should I do if the crimps do not pass the go/no-go gauge test?
A: If the crimps do not pass the gauge test, it is advisable to re-adjust the handle distance and recheck until satisfactory results are achieved. If issues persist, consider replacing the tool.

Q: How can I maximize the tool’s lifespan?
A: Regularly lubricate the linkages, avoid exceeding handle distance limits during adjustments, and follow proper maintenance procedures outlined in the user manual to ensure maximum tool lifespan.

Instruction

Connection Assembly
Cut the tube so that a clean, straight end is provided. Slide the crimp ring over the tube end. Insert the fitting into the tubing until the shoulder of the fitting contacts the tubing end. Position the crimp ring 1/8″ to 1/4″ (3.2 to 6.4 mm) from the cut end of the tubing. Place the opened jaws of the PEX Crimp Tool around the crimp ring. Check to be sure that the crimp ring is still properly positioned. Compress the tool handles to complete the assembly.
CHECK ALL CRIMPS WITH GO/NO-GO GAUGE

Gauging Procedure

1. Determine proper size of tubing: 3/8″, 1/2″, 3/4″ or 1″
2. If GO cavity fits over crimped ring and NO-GO does not, tool is crimping properly.
3. If GO cavity does not fit then handle distance must be increased.
4. If GO fits—check NO-GO. If NO-GO fits over crimped ring, the ring is over-crimped, decrease handle distance. Recheck.
   NOTE: Over-crimped and under-crimped rings must be removed from tubing. Crimp with a new copper ring.

Adjustment Procedure

1. Close tool handles until pre-load is reached (this is the point at which jaws touch). Tool should not be completely closed.

2. Measure the distance between dots on the handle ends as shown. 8-1/4″ – 8-3/4″ is the correct distance. If the distance is not 8-1/4″ – 8-3/4″ the tool must be adjusted.

3. To change the handle ends distance, remove the #6-32 eccentric lock screw with an Allen wrench and push up eccentric from back. Rotate eccentric counter-clockwise to increase the handle distance and clockwise to decrease handle distance.
   Move eccentric until hand distance is between 8-1/4″ – 8-3/4″.
   Push down eccentric and re-install the #6-32 lock screw in the appropriate hole which most closely yields the desired handle distance.

4. Recheck the set distance after making three crimps. The distance should be 8-1/4″ – 8-3/4″ between the “dots” on the handles.

5. Check the crimps with the go/no-go gauge provided. If satisfactory crimps do not result, the tool is likely worn and should be replaced.

Tool Maintenance

1. Check tool calibration daily. It is recommended that at least the first and last crimps of the day are tested.

2. Never exceed the specified handle distance when adjusting your crimp tool.
   Premature wear will result.

3. Lubricate linkages on a regular basis to maximize tool life.
