  • This adapter is especially helpful with high-pressure drop-stitch inflatables.
  • The threaded male end screws into your Leafield C7 Valve, sealing the O-ring for an airtight, secure connection.

  • C7 Leafield Valve Adapter

    Q:

    How does a C7 valve work? Do you inflate in the "open" position and the internal raft pressure then keeps it closed? After inflating do you then depress the star valve to open it in order to deflate?

      A:

      Inflate in the CLOSED position. This is a one-way inflation position where air can go in but not out. OPEN allows air to go both ways and is used for deflation. Be careful manipulating the star valve. It can be broken when subject to too much force. Push in and turn about a quarter turn is all.

      A:

      Inflate with the valve closed. Turn star clockwise (star out) it acts as a
      one-way or check valve so air goes in but not out. This way you don't lose
      any air while detaching the pump from the valve. Deflate by turning star
      counter clockwise (star in). This keeps the valve open to let the air out.
      If you have a reversible air pump, you can use it to help fully deflate the
      raft, ie suck out the last of the air. Hope this helps. -Mark.

      A:

      When the inner portion is turned clockwise it automatically closes if there
      is air in the chamber. This is the position that should be used for
      inflation. When turned counter-clockwise the valve will remain open for
      deflation.

    Can this be used to attach to an electric air compressor?

      A:

      While you could certainly come up with a way to attach this to an electric compressor, it's not recommended. Compressors put out much higher pressures than even the drop-stitch constructed crafts can take. You'll need to use extreme caution to avoid damaging your inflatable with over-inflation, which won't be covered under most warranties.

      A:

      Yes. But be very careful to not over inflate. If you are using a 100lb compressor for example, you can push the last few pounds in that the hand pumps struggle with. Take it off and check the board or raft pressure after a reasonable time from the electric. Get to know your compressor and write down how many times or how long it takes to get to your board or raft's max pressure. Do not over inflate!

      A:

      It will work, but requires adapters that you may have to make yourself.  You will have to be able to fit the outlet on the air compressor to the plain tubing that is on the Leafield Valve adapter.  In the past I have taken a tubeless tire valve (available at an auto parts store) and whittled down the rubber at the base of the valve stem until it fit snugly into the tubing I needed to fit snugly over a canoe airbag valve.  That way I could stop at a gas station and use the air hose which has a tire valve fitting on the end to inflate the bag for the canoe.  You can rig something similar for your compressor and the Leafield Valve adapter.

      I wouldn't think it would be a problem, you'd just need to step down the size of the hose to fit your air compressor.

      Yes! I've done just that & it works great. Better keep track of the pressure, however. Your typical workshop compressor will EASILY put out 100 PSI but most inflatables call for 15 or less.

      A:

      Bjorn, the C7 Valve has threads molded inside the opening that match with the threads of this adapter. The A7 does not have those threads so the adapter will not work with it. The Leafield/Military Valve Adapter, Item # 38524.01, does fit the A7 and gives a good seal.

    Q:

    is there a way to attach a Schrader valve to the c7? I need to be able to tell how much pressure is in the inflatable. I am filling the inflatable up from a air bottle fitted with a regulator and air hose. thanks

      A:

      A typical inflatable needs only 2 to 4 psi. Schrader valve gauges usually
      read much higher pressures. Why not get a gauge made specially to read a
      C-7 valve? NRS has several different ones. Hope this helps. -Mark.

      A:

      I don't know of a commercial connector, but I think you can Macgyver one by putting a tubeless tire valve stem down in the barrel of the adapter and epoxying it in with G/flex Epoxy Adhesive, Item # 50201.01.

      A:

      Actually, I did just that. Sorry I have no photo but I cut the valve out of
      an old inner tube, pushed it through a grommet from the plumbing department
      of the local hardware store, shoved it into the tubing of the adapter and
      held it all together with a hose clamp. Works great for topping off the
      inflatable. Hope that helps.

      Steve, it depends on the age of your boat. If it has Leafield C7 valves it will work. Use this reference page to identify your valve type - http://www.nrs.com/repair/valves.asp?tn=70

      If you go online just look for the Leafeild C7 adaptor.  I believe it's about $6 dollars, I also purchased a 12vdc car plug pump that works great for adding pressure after towing to boat launch.

      A:

      It just unscrews, there is a star shaped tool that matches the shape of the valve that you use as a wrench to turn it. I guess you could use a large pair of pliers or channel locks as well. There are repair kits and replacement valves available through NRS. If the valve body has an O ring seal on it, I usually coat it with plumbers grease (available at any hardware store) before putting the new valve in.

      Use the C7 Valve Wrench, Item 1482.1, to remove the outer portion of the valve. All the working portions are in this piece. All you may need to do is clean it. For further help, give us a call, 800.635.5202.

                    Slid right on the end of my K-pump to allow a bit of side to side flex when pumping. Without this adapter, you have to shove the K-pump straignt into the Leafield C-7 valve and hold is fairly straight. With the adapter you press & 1/4 turn twist for a solid pumping action around your gear, legs, cooler, etc... Nice (and quite simple) product. Glad I purchased it.

I can inflate and deflate the boat by myself in less than 10 minutes. The 'installation' is easy too: just plug this thing on top of one of the adapters that come with AHP-F1 pump.
