How to work boston valves?

To operate Boston valve, insert valve body into valve base, and thread securely by turning clockwise. Inserting the valve body into the base is best done with cap attached. Once attached, remove cap to prepare for inflation. Insert pump hose with Boston fitting firmly into valve for inflation.

To deflate, leave cap in place and unscrew valve body by turning counterclockwise.

  • Why my Chinook 120 has two different size Boston valves? The side bladders have standard size Boston valves, but the floor is smaller and my pump doesn't have an attachment that fits. I had to improvise using the pinch attachment and a hair tie to fit it in snuggly so I could pump the floor bladder. I am glad I like to test my equipment before taking it out on the field to avoid unpleasant surprises.

  • Bought your kayak and your pump. Virtually NO visual or written instructions included that would be helpful to any human being who has not done this before. No description as to the various parts or where they are and how they fit together. How do you securely connect the pump to the valve? Nothing fits. What comes off? What stays on? This video doesn't show anything but the tip of the pump hose. How did you connect the pieces? All I have are a few chunks of plastic. I'm left guessing about everything.

  • I agree totally with mh. The pump fits a Halkey Robert's valve. The kayak has a Boston valve. Sobthe pump comes with a bunch of adapters which have to be strung together. No instructions, yet one of the connections is so unintuitive that I took me half an hour before I figured out that it needs to be turned with force to engage.
    And the Boston valves are less than useless. The kayak has explixit warnings about maximum pressure, yet the valves do not alow for air to move freely to the pump, making it impossible to measure pressure with the provided gage.
    And then there is the "easy" air release, which is anything but easy. The valves do not screw out easily. I needed to use a wrench to loosen the valve so I could let the air out.
    Frankly I do not understand why they didn't just install the Halkey Roberts valves on the Chinook. We have a Deschutes with those valves, and it's such a breeze to pump up and deflate. The pump connects well with the valve, the pressure gage shoes the pressure, and the valve reliably performs. The Chinook, on the other hand, is a major hassle, and we may end up returning it precisely because of these valves.
