How To: Military Valve Repair and Replacement (4:21)

The military valve used on inflatable rafts and other watercraft is a very durable and dependable unit that's been used for years. It's especially found on older boats. Replacing the valve itself is pretty simple; just six screws hold the valve in place. However, generally the valve is installed in a recessed boot. Replacing a boot is a pretty major repair job. In this video NRS Repairs goes over all the steps for repairing and replacing military valves, including replacing a boot.

    Q:

    I have a raft now with these valves stuck in the closed position. Is there some sort of key or cheater on the market to unlock them? Also, is there any converter or way to switch from military?

      A:

      I'm not sure the best route to take if your valves are stuck. Perhaps
      making sure they are warm and not frozen shut? Usually if you try to turn
      them with steady pressure they will eventually move. I am not aware if
      there is a conversion kit (that would be nice!). I no longer have a boat
      with military valves. Upgraded to a NRS Otter last year. Perhaps NRS has
      one?

      A:

      There must be either something gumming up the threads or something adhering the rubber seal inside to the valve body. Remove the screws that hold the valve to the valve boot and remove the valve. Then you can try things like some penetrating oil, soaking the valve in warm water, etc to loosen up what's keeping it from opening. And yes, you can switch from the military valves using the procedure shown in this video - http://www.nrs.com/learn/how-to-replace-a-raft-valve.asp - The additional step you'll need to do is remove the military valve boot. You can use a combination of a heat gun and solvent to get that job done. If you have questions on the procedure, give us a call - 800.635.5202.

    Looking to buy new gaskets for the Achilles valve. Do you have these available?

      A:

      We don't stock a gasket for military valves. Most folks in our experience lay down a bead of silicone sealant under the valve before screwing it down.

      They fit in my boat perfectly. I have a 12' 6" Riken Dodger 2 and they are
      working great. I'm not sure what year my raft is but I assume it is a mid
      90's boat. Hope that helps.

      A:

      I have a Riken Jualapai. Not sure what year but it dates at least from the late 90's. I have used this valve to relplace some of the original nylon valves that failed due to age. The screw holes don't line up perfectly but thay are close enough that they go in without any real problems. The stainless screws that NRS sells for these valves are slightly longer than the original so I re-used the original screws without any problems. Note that the metal "military" valves that look just like these NRS valves do NOT fit. The flange is a bit larger and the holes are spread our furher and do not line up.

      A:

      These valves should fit in Riken boats. The Riken valve boot is narrower at the bottom than other military valve boots. Check your existing valve - if the outside diameter of the bottom flange is 2 3/16", this should work for you.

A better replacement valve

Pros

  • Excellent Build
  • More Durable Than Nylon

Cons

  • More Expensive Than Nylon

    Comments about Riken/Achilles Replacement Military Valve:

    This valve is a replacment for my Riken raft. The original valves disintergrate with age. These valves are MUCH better than the nylon replacements and seem to be much more durable. I am gradually replacing all the valves on my boat wtih these valves.

      Comments about Riken/Achilles Replacement Military Valve:

      This is a better valve than the older ones I have replaced them with. You may want to consider cutting out the old valve and replace it with a newer design. That is a lot more work than just putting one of these in.
