Learn how to replace the slider top on your HydraPak Velocity IT reservoir with simple steps and a leakproof seal.
Quick answer
You can replace the slider top on a Velocity IT in under a minute by removing the old one and pressing in a new HydraPak Velocity Slider Top. No tools are needed, and the included tether keeps the part from getting lost on the trail.
Why you might need a slider top replacement
The slider top on the Velocity IT sees constant opening and closing during runs, rides, and hikes. Over time, the sliding mechanism can become stiff, the seal may wear, or the tether tab can break. Replacing just the slider top—rather than the entire reservoir—saves money and keeps your favorite bladder in service.
If your reservoir still holds water without leaks but the slider feels gritty or doesn't close fully, a new slider top is all you need. The HydraPak replacement is made to match the original fit and sealing geometry.
Steps to replace the slider top
- 1. Remove the old slider top: Grasp the existing slider top by the edges and pull it straight off the reservoir port. If it feels stuck, rock it gently side to side. The slider is held by friction alone—no tools or twisting. Don't pry with a knife or screwdriver; that can damage the port or reservoir material.
- 2. Inspect the reservoir port: Check the plastic port ring on the reservoir for cracks, warping, or debris. Wipe it clean with a damp cloth if needed. A damaged port will prevent the new slider from sealing. If the port is cracked, the reservoir itself needs replacement—the new slider top won't fix that.
- 3. Attach the tether to the reservoir: Pass the small loop on the slider's tether through the ring or slot on the reservoir's carry handle, then pull the slider top through the loop to secure it. This prevents losing the part on the trail. Make sure the tether is not twisted or wrapped around anything before you close the loop.
- 4. Press the new slider top into place: Center the new Velocity Slider Top over the reservoir port and press down firmly with both thumbs until it snaps into place. The slider should sit flush and rotate freely in the closed position. If the slider tilts or feels loose, remove it and reseat it—don't force it.
- 5. Test the seal before your next adventure: Fill the reservoir partway, close the slider, and squeeze gently. No water should escape around the slider top. Open and close it several times to confirm smooth operation. Test with cold water (trail temperature) since warm water can make a temporary seal that fails when it cools.
