Union -Metric/Imperial SUS304/SUS316

Bolton 316 stainless steel tube fitting unions are widely used in oil and gas sectors, instrumentation, high-pressure equipment, metal or hard plastic tube connection demands, and structural applications, which require the precisive size specification-the outside diameter(OD), usually states millimeter(mm) or inch(“ or in). The features of 316/316L stainless steel are suitable for food and beverage industries, and medical equipment subject to special treatment.

All parts of tube fittings are made of 316 stainless steel, constructed by the body, back and front ferrules, and nut. Bolton provides various configurations of tube fittings for selection, including straights, 90-degree elbows, tees, bulkheads, nuts, ferrules, plugs, and caps. Nut threads are electroplated to prevent wear and improve smoothness for easier installation.

FEATURES
Double-ferrule metal to metal sealing, leak-free design.
Nut threads are electroplated to reach wear resistance.
316 stainless steel material features resistance to heat, impact, and corrosion.
