The product is said to help prevent heat damage to components and surrounding material during soldering, brazing, and welding. Specifically it is said to protect seals and seats in ball, dielectric, and solenoid valves as well as protecting soldered joints from loosening when soldering adjacent joints. It also protects from buckling or distortion of thin metal sheet during brazing and welding.
J.W. Harris (www.jwharris.com) introduced a self-lighting torch, air fuel outfits, air fuel tips, regulated hand torches, oxygen/acetylene kits, a single-stage nitrogen regulator, and related accessories.
Klenk Tools (www.klenktools.com), a division of Everhard Products, featured a line of hand tools made of extruded aluminum. The company said the folding tools are less than half the weight of similar steel tools complete with one-piece, no spot weld construction and finger ridges for better grip. A sight hole allows proper depth alignment.
Mastercool (www.mastercool.com) highlighted its Accu-Charge II electronic refrigerant scale line of refrigeration and air conditioning service tools. â€˜Charge Programming' allows a user to program desired quantities. Before a charge is complete, an alarm will sound, giving the technician time to turn off the refrigerant supply.
Midwest Snips (www.midwestsnips.com) unveiled upright snips, billing the tool as "a revolutionary way to cut sheet metal and other materials." The configuration "avoids the need to bend the wrist while cutting metal in many common applications." Applications include confined areas, overhead, push and pull cuts.
The Mill-Rose Co. (www.cleanfit.com), Clean Fit Division, presented a shut-off tool called the Water-Gate. The tool is used as a fluid shut-off device for installation, repair, or replacement work. It is available in Â½- to 4-inch sizes. Seals are made of neoprene rubber and fit full port domestic and imported valves. They are compatible with R-404A and R-410A. The company also showed the Ringcrusherâ„¢ decrimping tool, created to remove crimp ring and PEX tubing from fittings.
Nu-Calgon (www.nucalgon.com) featured R-11-FlushÂ®, which according to the company, allows flush line sets when converting to 13 SEER equipment. The flush is said to remove existing oil, moisture, etc. from line sets. The product also flushes coils and line sets after burnouts and is said to have a low boiling point.
