PROCEDURE

1. Using a razor or similar cutting instrument, slice length-wise down the PFE tubing the full length of the barbed fitting.
2. Remove the tubing from the barbed fitting.
3. Using a tubing cutter (700001012), recut the end of the tubing. Ensure that it is evenly cut.
4. Using a small awl or similarly shaped tool, widen the inside of the end of the newly cut tubing to make installation easier.
5. Cut a piece of medium-grit sandpaper into a 1-2 centimeter square.
6. Fold the sandpaper square in half between your thumb and forefinger.
7. Use the sandpaper between your fingers to grip the PFE tubing approximately 2-3 mm from the end.

9. Gently guide the PFE tubing onto the barb of the needle wash or BOS pump until it is secure.
