Hoke Inc. has announced the extension of its double ferrule flareless tube fitting offering to include sizes 1¼â?, 1½â?, and 2â?. Hoke flareless tube fittings are now available in fractional sizes from 1/16â? through 2â?. Hokeâs metric offering has been extended as well, and now includes sizes from 3mm to 38mm. Fittings in sizes over 1â? (25mm) are offered, as standard, in 316 stainless steel. As with all Hoke flareless tube fittings, the pressure ratings for these new, large diameter, Hoke fittings are higher than the Maximum Allowable Working Pressure of tubing that is suitable for use with flareless tube fittings. Hokeâs flareless tube fittings, in all sizes, provide safe, leak-free, reliable performance from cryogenic temperatures to high temperature bake out levels. The large diameter fittings were developed to meet the demanding requirements of the chemical, petrochemical, oil and gas, industrial, and alternative fuels markets. This extension to the Hoke Gyrolok tube fitting line offers a broad selection of sizes and connection types, including various straight connectors, adapters, elbows, tees, and reducing tees.
