Press-connect joining takes advantage of copper's excellent malleability and its proven increased strength when cold worked. The joints rely on the sealing capability of a special fitting that …

To achieve high pressure performance, press-connect fittings for HVACR service utilize one, or a combination of several design changes which may include changes in: 1) the o-ring/gasket …

Properly positioned press tool Depress the pressing tool trigger to begin the pressing cycle. When the pressing cycle is complete, release the pressing jaw and visually inspect the joint to ensure …

In designing a system, tube, fitting and joint ratings must be considered collectively, because the lower of the ratings (tube, fitting or joint) will govern the maximum installation design pressure. …

Press joints. Press joints are applied in order to permanently join two pipe sections together. The joint is made by mechanically crimping a special fitting containing an o-ring onto the pipes. …

Newer methods for most general plumbing applications include solderless Press-connect and Push-connect fittings, which incorporate an elastomeric gasket or seal (such as EPDM). The …

ASME B16.22 establishes specifications for wrought copper and wrought copper alloy, solder-joint, seamless fittings, designed for use with seamless copper tube conforming to ASTM B88 …

While copper tube is usually joined by soldering or brazing, there are times when a mechanical joint may be required or preferred. Flared fittings (Figures 28 and 29) are an alternative when …

Investigations into the common causes of joint failures revealed several factors contributing to faulty joints, including: Improper joint preparation prior to soldering. Lack of proper support …

1 Standard water tube sizes per ASTM B 88. 2 Ratings up to 8 inches in size are those given in ASME B16.22 Wrought Copper and Copper Alloy Solder Joint Pressure Fittings and ASME …
