Roll Grove Joints:
Installation Steps

Examine the tube to ensure there are no dents, deep scratches, dirt, oils, grease or other surface imperfections (Figure 10.1).

Figure 10.1. Inspect tube for imperfections

Measure the tube length accurately (Figure 10.2).

Figure 10.2. Measure accurately

Cut the tube end square, i.e., perpendicular to the run of the tube (Figure 10.3).

Figure 10.3. Square-cut tube end

Remove burrs from the I.D. and the O.D. of the tube end by reaming the I.D. and chamfering the O.D using the appropriate tools (Figure 10.4).

Figure 10.4. Clean and smooth tube end

Roll groove the tubing to the proper dimensions, as required by the fitting manufacturer (Figure 10.5).

Examine the fittings, gaskets and clamps to ensure the proper gasket is inserted into the clamp and the fitting end is not damaged (Figure 10.6 and 10.7).

Lubricate the gasket per manufacturer's recommendations (Figure 10.8).

Inspect the clamping surfaces to ensure they are clean and free from construction debris (Figure 10.9). Assemble the joint according to the manufacturer's recommendations (Figure 10.10).
