“Tubular pressure check and valve tightening require simple procedures that should not be underestimated. Our advice is to proceed systematically as described.”

Tubular pressure check and valve tightening are important aspects in the context of operations aimed at appropriate use and maintenance of the inflatable boat. Correct inflation of the tubes and tightening of the air valves are simple procedures not to be underestimated. Our advice is to proceed systematically as described below:

• Deflate all compartments of the boat until they have lost rigidity and partially their shape.

• Inflate all tubes again, starting from the stern chambers first, and then inflate all the others in succession, finishing with those at the bow.

• Each air chamber should be inflated to a high pressure, using a pressure gauge to reach about 0.30 bar or at least to the maximum pressure achievable with the provided inflator.

• At this point, insert the provided key into the notches on the valve without the cap and firmly hold it with the other hand to prevent the key from slipping when exerting pressure, then tighten with firm strokes until fully tightened.

• To exert more force, you can insert a metal tube 30/35 cm long or a rigid plastic tube into the handle of the key to increase the leverage effect.

• After completing the operation, deflate the air chambers to bring them back to the correct pressure (approx. 0.25 bar) and tighten the valve cap securely.

• Check with water and soap that there are no leaks around the valves.

• Check the pressure variation of each air chamber, even just by touch, after two or three days, and if no changes are perceived, continue for at least 10/15 days.

If, after 10/15 days, there is no evident leakage in any air chamber, the inflatable boat is fine. It should be noted that the pressure inside the tubes varies greatly and frequently. Temperature variations, exposure to sunlight, and immersion in water affect the volume of air; this effect is more noticeable the larger the diameter of the tubes. It is therefore recommended to always check the pressure under the same conditions to accurately assess any changes.
