Swagelok^® 螺母，前后套环

Swage tubing coupler has four parts namely the body, into which the tube is placed, two ferrules that is front ferrule and back ferrule and lastly a packing nut. While assembling a compression tube fitting, the metal tubing should be inspected properly to ensure that the surface is smooth. A nut is slided on to the tube fitting with the open side facing the end of the tubing. Followed by sliding the back ferrule with the wider part facing the nut. Further, sliding on the front ferrule with the small end of the cone facing the end of the tubing. Then inserting the tubing into the fitting and tighten up the nut/ferrule assembly onto the fitting.

Swagelok^® nut, front and back ferrule set maybe used for sampler construction from a single capillary gas chromatographic column, for collection of semi-volatile organic compounds through a diffusion denuder.
