Step 8 · Tighten the Coupling Bands to Spec

This is the step most people slow down on. Take it one move at a time — there’s no rush, and you can rewind the clip as many times as you need.

This step is critical for a long-lasting, leak-proof seal. Using a torque wrench fitted with the correct size socket (usually 5/16" or 8mm), tighten the stainless steel band clamps. Refer to the coupling itself for the manufacturer's recommended torque specification, which is typically 60 inch-pounds (in-lbs). Tighten the clamps in an alternating pattern to apply even pressure across the gasket. Continue tightening until your torque wrench clicks, indicating you have reached the specified torque. Do not guess or simply tighten until it feels 'tight enough,' as this can lead to leaks or damage.
