Parker's two-ferrule compression fittings, A-LOK® Series 3/16" Tube OD x 1/8" NPT male connector tube fittings are designed to provide reliable leak-free connections for instrumentation, process and control, and analyzer applications that specify a two-ferrule tube fitting connection. Manufactured from dual certfied 316/316L these austenitic grades and two of the most used alloys in a variety of applications. The molybdenum addition gives this grade good resistance to general corrosion and provides increased strength at elevated temperatures. The austenitic structure also gives these grades excellent toughness, even at cryogenic temperatures. Grade 316L, the low carbon version of 316, minimizes harmful carbide precipitation due to welding. It is common for 316 and 316L to be stocked in ‘Dual Certified’ form. These items have chemical and mechanical properties complying with both 316 and 316L specifications. The corrosion resistance of stainless steel grades 316/316L is excellent in a wide range of atmospheric environments and many corrosive media. However, it is subjected to pitting and crevice corrosion in warm chloride environments, as well as to stress corrosion cracking.
