About This Product

The Master-FLO hose valve is jam packed with features every DIY-er will appreciate! FLOW CONTROL: The Master-FLO valve features begin with a full 5/8 in. I.D. (same as a standard water hose), enabling maximum force by minimizing water friction. Then, extended control lever enables precise, continuous control of water volume flow (turning clockwise) to meet exact need. SHUT OFF: when turned fully, the valve shuts the water off, up to 125 PSI. This is an important feature when using a nozzle with no shut-off such as a fixed sweeper nozzle. The SWIVEL BASE works effortlessly to avoid hose kinks. The COMMERCIAL LENGTH MALE (THREADED) END ensures that the Master-FLO valve can be used with any residential or commercial nozzle which may have a deeper hose coupler. The Master-FLO flow control and shut-off valve will make all watering jobs easier and more efficient.


  • Fully adjustable flow control with shut-off, up to 125 psi
  • Easy-twist extended control lever
  • Full 5/8 in. inside dimension (ID) maximizes source pressure by limiting water friction associated with step-down flow
  • Swivel base limits hose kinks

I got this shut-off to help with hand mobility issues. It is very well built and sturdy feeling. The blue ball valve shut-off handle fits nicely in the hand and is not difficult to operate. The ball valve completely stops water flow and does not leak. We have had them a month, use them daily. They have been dropped several times and have not shown any damage or functional issues. Its durability and ease of use make this a good buy in my opinion.

Good Valve
my wife wanted this for our garden hose, it looked good so i ordered it. it arrived in 3 days well packed and in perfect condition. it feels light but solid and looks to be very well made. it has a very positive feel and is a quarter turn on/off. the knob has open & close markings for which way to turn. this is a very nice shut off valve and my wife likes it.

Nice hose end with big lever
What I love about this hose end is that it attaches easily, doesn’t leak, and has a oversized lever. This would be great especially for folks that struggle with the hose ends that have those tiny levers that require a lot of gripping force. My only worry with this is that it’s completely plastic and I’ll have to be careful as I roll up the hose and pull it from place to place as it seems like it could break easily.

Water Flow Controller - Perfect for Gardens!
The Water Flow Controller/Shut-Off Valve with Full 5/8 in. I.D. has various settings to be able to water any residential garden. Can be easily added to a standard water hose and quickly twist the control lever to different settings or completely shut off. Liked that it was quick to install & didn't leak like other water flow accessories. Works great!

Convenient shut-off valve
The water flow shut-off valve provides convenient control of water flow at the hose end without returning to the house. The valve allows you to turn off the water and change attachments without getting wet. It is very convenient when watering plants and washing the car. Having a convenient shut-off valve allows you to conserve water by easily shutting it off when not in use.

Master-FLO hose valve - easy to use
The Master-FLO hose valve is very easy to use - just screw it on the hose and the connector for a leak free connection and turn it on. The large lever makes it easy to turn the water on, off or to restrict the amount of water coming out. Since it's made of plastic, it can be used with both aluminum and brass hoses and nozzles, without worrying about it corroding. This shut off valve doesn't restrict the amount of water available, as the inside of the valve is 5/8". The male end is longer than the typical home connector, and has more thread, which also makes this ideal for a commercial application.

Heavy Duty
I use a lot of garden hose shut valves with my pressure washers, irrigation system, and outboard motor repair. This is by far the best one I’ve used. The large shut on/off handle makes opening and closing the valve easy, even when wearing gloves. Being a ball valve, it opens and closes even under pressure. The full 5/8ths inch bore assures the is no restriction in flow or pressure. It is built very robust, and I expect a long service life.

Very handy to have!
This is the sort of thing that you didn't know you needed, but you're very glad to have it. Often times, we find ourselves in a situation where we need to turn off the hose to change what type of sprayer or sprinkler or other hose attachment we're using. Put this on the end of the hose instead. It saves you from having to walk all the way back to the house to turn the water off, walk all the way back to the other end to change your attachment, and walk all the way back to the house to turn the water on again. Nothing against walking, but it's time consuming. This little gadget saves you time! It's well constructed and it doesn't leak. I'm probably going to buy a couple more for my other hoses.

shut off valve
The Water Flow Controller is top quality. Made of plastic, it has a 5/8 inside dimeter and the shut off position has a detent, knowing that you are in the full closed position. It is rated up to 125 pounds per square inch. and has a 90 day manufacturers warranty. I had no problems installing and it didn't leak after installation. I would recommend this as installation can be done by anyone. Directions were clear.

Well worth spending a little extra for the quality this valve provides
When looking for a shut off valve to put in line on my water hose, I looked at some of the low cost units with little handles, but this full port ball valve really met my needs much better. Once it is tightened to the hose end, it can be rotated so the handle is in the best position for use. The full length male threads make being able to fully tighten hose thread accessories without leaking easy. The large handle makes control of flow and operation much easier than the small flip handles of smaller units.
