Chrome Plated Supply Stops are great for this application because they have a wide range of connections including copper solder connections, PEX connections, and compression connections.
A Chrome Plated Supply Stops is a shutoff valve and it would be necessary right before an appliance when you need to turn the water off right at the appliance in an emergency or for servicing. Since water supply lines typically come in through the wall or up from under the floor, the supply stop acts as the shutoff valve accessible right at the appliance opposed to a valve at the beginning of the supply line in another part of the house.
The video below is the Chrome Plated Supply Stop training webinar will focus on a general overview of what these products are, where they are used, and different styles available.
No Lead Chrome Plated Supply Stops valves are certified to the NSF/ANSI Standard 61 & 372 and the CSA Standard B125.1. Available in a multitude of designs and sizes to meet your connection needs.
Will we be adding water hammer arrestors to the washing machine valves?
This is now under consideration. We will advise on any future changes.
Are all Boshart chrome plated supply stop handles and stems plastic?
The color coded washing machine valve handles are metal; ALL other supply stop handles are plastic.
The dual outlet/dual shutoff valves (MULTI TURN) have plastic stems; ALL other supply stops (1/4 TURN) have metal stems.
Has Boshart considered adding supply valves with a Rehau Inlet?
Again, this is something that we are now taking under consideration.
Is it code to have a supply valve at every appliance?
Supply valves are required by some codes. Check the plumbing code in your jurisdiction before installing appliances.
Are the multi-turn valves serviceable?
This is true. The packing nut can be removed and components like the plunger, stem, packing nut, and handle can all be serviced or replaced. Currently, Boshart’s cannot offer the replacement components but this is also under consideration. That said, the ¼ turn valves have a more simple, robust design that can expect longer life expectancy.
Hello and welcome everybody to our webinar on Chrome Plated Supply Stops. We’re glad you decided to join us.

In this first section we’ll get into just WHAT chrome plated supply stops are. This will be perfect for those of you watching that are looking for an introduction into these types of valves.
Now, let’s get into where these valves are used.
There are 4 major designs in these valves, and they are a straight through design, a 90-degree elbow design, a dual outlet or “T” design and a dual outlet/ dual shutoff design.
The angled supply stop would be used when the inlet and the outlet need to be perpendicular. An example of this is when the supply line comes through the wall and needs to go up to an appliance. The supply stop would make a clean 90-degree elbow in the supply line up to that appliance. Really, the key thing to think about when deciding between these first two is that you don’t want the supply line leaving the chrome plated supply stop heading towards the appliance to be bent too sharply which could result in a kink.
Thirdly, the Dual Outlet supply stops are used when you would like two appliances to run off one supply. A common example of this would be hooking up a drinking water faucet and a refrigerator on one line.
The Dual Outlet Dual Shut-off supply stop could be used when you’d like two appliances to run off the same supply but would also like to be able to service one appliance while keeping the other running. This is the only chrome plated supply stop that Boshart Industries offers with a multi-turn design.
Now we’re going to look at some of the different designs of these valves and when they are used. We’ll talk about the difference between a quarter turn supply valve and a multi turn valve. There are two types of operating design for chrome plated supply stops and they are 1/4 turn ball types and multi-turn types.
Most people are comfortable just knowing that for 1/4 turn valves, you only need to turn the handle 90-degrees to turn water on and off and for the multi-turn valves, you need to turn the handle several times before the water is turned on or off. It really comes down to preference of these two actions when choosing an operating design. For instance, some may find it easier to turn the 1/4 turn valves in a tight space than to turn the multi turn valves, which require more action. For those who are looking to know the technical differences, the 1/4 turn ball types operate by turning the handle which turns the semi open ball inside the valve 90-degrees to shut off flow. You can see arrow number 1 on the line drawing pointing to the ball and arrow number 2 pointing to the handle. Aside from the easy operation of the ¼ turn valves, the 1/4 turn design is also gaining in popularity because they are less apt to seize than the multi-turn valves after being installed and left alone for a long time. How they get seized is that there are a lot multi turn valves that have metal stems and packing nuts which, left unused, can corrode or have mineral buildup that will cause the valve to seize in the open position.
A multi turn valve operates by screwing a stem and plunger down onto an opening in the valve. Arrow number 1 on the line drawing is pointing to the plunger, which is pushed down on the opening, so this particular valve would be closed. And arrow number 2 is pointing to the handle and stem assembly. Here at Boshart Industries, our multi turn chrome plated supply stops have plastic stems, which has helped us to avoid the seizing problem.
Boshart Industries offers several models with quite a few connection variations.
Most of the outlet connections, which is where the water flows out of, are 3/8” compression connections because most flexible supply tubing fits this size. There are a few exceptions to this; one of the straight valves with a 1/2” PEX outlet, all of the ice maker valves which have ¼” compression outlets, the washing machine valves which have 3/4” garden hose thread outlets, and some push fit variants with ¼” compression outlets. A feature on Boshart Industries compression connections is that the threads were made longer to meet the SAE J512 standard. The chamfer that compresses the sleeve was made to that same standard as well. We will go over why this was changed a little later.
Let’s go over some design features that the specialty supply stops offer.
The Ice Maker Supply stops have 1/4” compression outlets to work with ¼” supply hose which is typically used in ice makers.
Now we’ll go over a few of the items that our QC department is looking for when we receive these supply stops and go over why certain features were changed for the better.
We keep a close watch on the connections of the valves, making sure that they have been manufactured to the standards that they are designed from. This is done quickly with a calibrated gauge for national pipe threads and solder connections. We also have tools to monitor the alloy of the material to make sure that the correct brass alloy is being used in the valves. The R&D team here at Boshart Industries has engineered gauges that can quickly test push fit connections. As I had mentioned before, we changed the compression connections to meet the SAE J512 standard. This was changed to accommodate the use of flexible plastic supply tubing which would cause the compression nut to bottom out before making a proper seal. The threads were made longer and the chamfer for the sleeve was made to the new standard which has made sealing to plastic supply tubing effortless. R&D has designed gauges that quickly test the compression ends to the SAE J512 standard. Something else that we inspect is the disassembly torque.
We’ve created a Boshart specification for the force it takes to break the seal on the body joint which is 20 ft/lbs. This is particularly necessary in the off chance that a compression nut is seized and while trying to remove it, the body joint seal is compromised which would mean the entire supply valve would need to be scrapped and a new one installed in its place.
