The Fly High Check Valve Quick Twist Adapter is a two part fitting that replaces the Fly High Quick Twist / Sac Thread Adapter that comes with the Pro-X series sacs.


The Fly High Check Valve Quick Twist Adapter is an optional upgrade for Fly High Pro X Series ballast bags that replaces the standard Quick Twist Adapter. Just as easy to connect and disconnect as the standard fitting, the W744 Check Valve adapter also features an integrated check to prevent water from exiting the bag when disconnecting and connecting the pump for filling or draining.

Don't worry about water shooting back into the boat when you disconnect your Fly High Tsunami pump. Fill the sac normally using the twist connect system. When it is time to drain connect the included fitting on your pump to push through the rubber diaphragm and allow the water to come out.

If you want to keep your boat as dry as possible, this fitting is definitely for you, just remember that you'll need one for each ballast bag.

Fly High ballast fittings have been designed with you in mind. All of the fittings make connecting pumps and hoses to your Fly High Pro X Series Ballast Sacs™ a quick and simple task. No more struggling with old waterbed valves and water spilling inside the boat. Simply twist, pull, replace and you're ready to go! Fly High offers several different fittings that all work together to adapt to any of your needs.

    Keeps it Dry!
    Daniel Spohr

    Bought these valves for sacs on each side of direct drive. Easy to use and I' m able to fill the sacs all the way now. Just untwist the pump and your good to go. Gone are the days of untwisting the connection and water spraying out, while your trying to cap it. Highly recommend

    Works Ok.
    Chris Baldwin

    I bought two of these (one for each sack). The issue is, with these connected, the water pressure rotates the connection off (even if I pre-torque the connection), causing water to spray everywhere in the boat until you disconnect the pump or reconnect the hose... They work ok if you hold the connection tight, but that's a lot of holding. Not sure why these won't lock on. I've double checked all connections and gaskets/washers.... and tried removing the excess grease from the fitting, but no luck. At $40/ea, I'd expect these to seal better.

    Keep that water in check
    Robert Daves

    If you like to keep your boat nice and dry we're adding tons of water weight this is the valve for you

    Works As Advertized
    Ted E

    Works well if you fill bags using the pump. I will buy one for each sack I purchase to avoid spills.

    Great add for your portable fat sacs
    Joe V

    No problem with water spills on fill and empty and the hose stays connected if you contort the hose correct like the other fittings. Also with the check valve it sucks the bag flat with very little water left to dump over the side.

    They really do work

    I was so happy with them that I bought another pair for a friend. It's nice that water doesn't get all over the boat, and with boat that still has a wood core, this was key.

    Check Valve Doesn't Allow Any Water In The Boat
    MalibuVLX Guy

    The Fly High check valve has a great design and it works just like it is supposed to but I didn't really use it after the first couple times. If you are worried about water in your boat this is the perfect tool for the job. The only draw back is that you need to buy one of these per sac.

    The fly high check valve is a must have if you want to keep as much water out of your boat as possible. It is simple and easy to use. I haven't had any issues with the hose or pump staying attached to the check valve. Buy one today! You'll be pleased with your purchase.

    Not happy with its hook up

    The hose doesn't stay atttached to the check valve when filling or emptying it does its job as far as not allowing the water to flow out but just a pain to have to hold the connection in place the entire time have already removed it and just using the standard valve that came with the bags!
