Remove the PVC vinyl tube from the packaging and make sure to save the two repair patches included in the plastic bag. When preparing to inflate the tube, lay the tube down with the graphics facing upward and spread out as flat as possible. It is important to inflate the safety chamber first. Inflate the safety chamber to approximately 10" (25 cm) in diameter (about the size of a small basketball). Do not over inflate the safety chamber.

To inflate the main chamber of the tube, make sure the Boston valve is securely tightened by turning the round textured base of the valve cap to the right. Next, loosen the square top of the Boston valve cap by turning it to the left, while ensuring the round base stays securely tightened in place. Inflate the main chamber of the tube using a small air compressor, air mattress pump or blower until the tube takes shape and is fully inflated. Our custom PVC vinyl tube takes shape quickly during inflation. Do not over inflate the main air chamber of the vinyl tube. To close the Boston valve securely tighten the valve by turning the square top cap to the right. Refer to the Tube Pro™ photo at the bottom of page for a properly inflated tube.

To deflate the main air chamber of the tube, remove the Boston valve cap from the recessed valve port. To loosen valve cap turn the round textured base to the left. Next deflate safety chamber and fold and curl as necessary to remove excess air. Once the vinyl PVC tube is deflated, reinstall the Boston valve core and tighten cap securely at the base for storage. Vinyl tubes should be stored without sharp creases in the PVC. Do not tightly vacuum the tube.

Note: Tube may naturally deflate due to seasonal air pressure changes. Additional air may be required before use.

**When re-inflating vinyl tubes, ensure the main chamber Boston valve is screwed in tightly.**
