These, together with the tubing, make a many variations found in the field, such as variations five-piece seal. in tubing tolerance, wall thickness, quality, the To ensure that the RELIANCE Tube Fitting provides installation procedures employed, etc. a reliable and leak-proof seal, it is important that the The RELIANCE Tube Fitting consists of four precision fifth component of this seal, the tubing, is selected, parts - the nut, the back ferrule, the front ferrule and handled and installed with great care. When selecting tubing for use with RELIANCE Tubing Surface Finish and Handling Tube Fittings, the following factors should be kept in mind : Scratches on the OD of the tube can be a 1. Tubing material potential source of leakage in a tubing system. 2. Tubing wall thickness A good surface finish and proper handling to 3. Tubing surface finish protect the finish help to reduce this potential. 4. Tubing hardness Tubing should never be pulled out of the tubing rack. This is particularly true of the larger Tubing Hardness sizes of tubing which weigh more and can get damaged on the OD by burrs on the ends of Tubing of appropriate hardness will go a long the tub
