Step 1 – Stripping CoatingMeasure and cut coating back per the dimensions shown in Table 1. Cut the coating half way through using a tubing cutter, cut the rest of the way through the coating using a utility knife. Take care not to score the CSST while cutting the coating.

Step 2 – Cut tubing to final lengthSlide nut completely onto tubing and add retainer (for this step it will be easier if you remove the o-ring from the nut). Care should be taken to not damage the coating when sliding the nut on. Mark the corrugation at the end of the retainer as shown in Figure 1. Remove retainer and nut, cut at the marked corrugation using the appropriate tubing cutter.

Step 3 Assemble the FittingATTENTION: Ensure that the o-ring is properly seated in the groove in the back of the nut and there is an o-ring installed on the fitting body before assembly.

Step 3.1 – Install the Nut and RetainerApply a silicone lubricant to the o-ring installed in the nut. Slide the nut over the tubing and place the retainer ring on the tubing. Leave one corrugation exposed from the end of the retainer to the end of the tubing. The small end of the retainer must point towards the cut end of the tubing as seen in Figure 2.

Step 3.2 – Install the BodySlide the nut over the retainer and thread it onto the body rotating only the nut. Figure 3.

Step 3.3 – Wrench TightenUsing appropriate wrenches tighten the nut until it fully contacts the body. Tightening torque should not exceed the maximum torque listed in Table 2. Do not use any thread sealant on the CSST Connection. Thread sealant should be used only for NPT threaded connections.

Step 4 - Vent/Pug InstallationIf venting from the 1/8” threaded port on the nut is required install the vent in accordance with local code. If no vent is installed, remove the 1/8” plug apply an approved pipe thread sealant and reinstall the plug.
