The company has expanded its hex jam nut inventory by adding sizes 1 to 11-1/2 NPT and 1-1/4 to 11-1/2 NPT. The nuts, which have a washer face, are molded in Nylon 6/6, and are recommended for installations of threaded pipe through sheet metal, composition board, or cabinet walls. According to the company, the nuts lessen the possibility of connection failure in high-vibration areas, along with providing moisture and thermal insulation in heating and cooling systems. The nuts will also reportedly seat on uneven surfaces, are resistant to chemical corrosion, vibration, and abrasion; are electrically insulating; and non-magnetic.
