G flat Knurled Female


The Swagelok knurled nut tube fitting provides a leak-tight seal without the use of inserts on most wall thicknesses of polyethylene tubing. Inserts may be required for larger sizes.


L


To set the ferrules on the tubing, initial connections must be made with a wrench, tightening the nut one and one-quarter turns from finger-tight (three- quarter turn for 1/16, 1/8 and 3/16 in.; 2, 3, and 4 mm fittings). Leak-tight connections may be reassembled with finger-tight assembly.


To order a knurled nut, add K to the female nut basic ordering number. Example: B-402-1K


To order a knurled nut on an assembled fitting with nylon ferrules, add KN to the fitting ordering number. Example: SS-400-1-2KN


To order a knurled nut on an assembled fitting with PTFE ferrules, add KT to the fitting ordering number. Example: SS-400-1-2KT
