2. Product Specification:

 
3.  Press Joining Method:

   Press joining is a form of mechanical connection for copper and steel tubing which uses a press tool, jaws, and rings to affix the sealing element and fitting to the tubing.

   Press copper joining systems offer a high quality installation that is faster and cleaner than traditional solder. Press copper joining provides a reliable long lasting installation both above and below ground. The tubing should be fully inserted into the fitting, and the press made according to manufactures instructions, using the press tool, jaws and rings reommended by the manufacturer. For applications other than domestic water contact the fitting manufacturer.

 Press joining for stainless steel pipe provides a fast, easy, clean and reliable means for installing 1/2”-2” (15-50mm) stainless steel piping systems. Press joining requires no flame or arcs as with welding; no cutting oil, chips or preparation time as with threading or flanging.

  EPDM sealing element

5.  Installation Instruction:

1. Cut the Tube

An appropriate copper tube cutter must be used to ensure a clean square cut. Note: It is important that the copper tube is cut completely square, the end of the tube (outside) must be clean and free from any scratches or damage such as dints or deformity.

2. Remove Burrs

Make sure that the internal and external tube end is completely free from burrs or sharp edges by using a file or deburring tool. Note: ensure over use does not affect the tube end outside diameter.

3. Inspect the Fitting

Before inserting the tube, check O-rings (15-50mm) and also spacers/grab rings (65-100mm) for correct placement, they are free of damage or any dust, dirt or debris. We recommend the fittings are retained in packaging up to the point of use where ever possible.

4. Making Insertion Depth on Tube

All cut and deburred copper tube ends for insertion into the fitting require an insertion depth make to be applied to the tube prior to insertion into the fitting. The mark will be applied by measuring from the end of the tube with a ruler or tape measure and using a marker pen to the required length. The mark will ensure the tube is inserted completely into the fitting prior to press.

5. Tube Insertion

The tube should be inserted parallel into the fitting coupling ensuring no damage is caused to the O-ring or grab ring and spacer (DN65-100mm0, ensuring the insertion mark is visible at the end of the fitting next to the fitting coupling end.

6. Press Tool Selection

The tool to be used must be conformant, well maintained and within its manufactures service requirement. The correct jaw type and size must be inspected to ensure it is clean and free from defects and contamination.

7. Press the Joint

The jaw must be placed over the fittings, correctly aligned and positioned. When all requirements are correct, the tool should be activated to press the joint. The tool should complete the correct cycle and the jaw ends should fully close on completion. If the tool does not complete the required cycle during operation the fitting must be cut out, replaced then repressed. No fitting should be pressed more than once. Tooling should be used as per its respective manufacturers’ documented requirements.

8. Joint Completion

The fitting should be inspected after pressing to ensure the correct press has been performed and no cracking or over deforming has occurred. The pipe insertion mark should be checked and be at the fitting edge, to ensure it has not moved.(DN65/DN80/DN100 has a sticker on each fitting that can be removed after press and inspection to ensure conformance).

6.  Minimum Soldering Distance Table:

      The minimum distance when making a press joint near a solder is in the table below. No residual solder, flux, or debris should be on the tubing.

9.  Frequently Asked Questions:

     Q: Can this brass press union be installed in a refrigeration system?

     A: No. The EPDM seals are not compatible with refrigerants, and the pressure rating of the system is not sufficient for many refrigerant gases.

     Q: Can the Press Fittings’ connection be re-crimped?

     A: Yes. Only to make sure, the pressing jaws must be positioned on the same hex flats as the

original crimp.

     Q: What’s the minimal order quantity for this series of product?

     A: In fact, it depends on which size do you need. For instant, 12” requires 3000 and 1” will be 2000pcs at least. For more details, please contact with our sales personnel.
