The Ceramic Disc Cartridge & Balancing Spool for 1H Pressure Balance Valve is a replacement plumbing component supplied with both a ceramic disc cartridge and a balancing spool. It is identified for use with a 1H pressure balance valve and has listed dimensions of 5 11/16 inches by 1 3/4 inches. The assembly is intended for situations where the valve’s internal replacement parts need to be changed while the surrounding bathroom fixture remains in place.
Quick Overview
This replacement assembly combines two internal valve components in one package. The ceramic disc cartridge and balancing spool are provided together, which may simplify the process of locating matching parts for a compatible pressure balance valve. The listed faucet body construction is solid brass, and the product information identifies the faucet as ADA compliant for bathroom faucet applications.

What Is Included?
The package includes two parts: a ceramic disc cartridge and a balancing spool. These components are associated with the internal operation of a pressure balance valve. Providing both parts together can be useful when a service job calls for replacement of the cartridge and balancing component rather than a single isolated piece.
The product information does not specify additional installation hardware, seals, trim, handles, or other accessories. Anyone replacing an existing valve component should confirm what is included before beginning the work, especially if the original assembly also requires new washers or other small parts.
Design and Construction
The listed faucet body construction is solid brass. Brass is commonly used in plumbing hardware because it provides a rigid base for components that handle water connections and repeated adjustment. For this product, the confirmed construction detail applies to the faucet body description. It should not be taken as confirmation that every individual internal part is made from brass.
The ceramic disc cartridge is paired with the balancing spool as part of the replacement assembly. Ceramic disc components are commonly used in faucet and valve mechanisms that regulate water flow, but the precise internal design, seal arrangement, and operating specifications for this particular assembly are not provided. Installation should therefore follow the instructions supplied with the part or the requirements of the existing valve system.
Understanding the Valve Application
A pressure balance valve is used in a bathroom water-control system to help manage the relationship between hot- and cold-water flow. Its internal components must match the valve body and handle arrangement already installed. In this case, the product is identified for a single-handle, or 1H, pressure balance valve.
That application detail is important because replacement cartridges are not universally interchangeable. Even parts that look similar may differ in length, connection points, stem design, or balancing-spool dimensions. The listed measurement of 5 11/16 inches by 1 3/4 inches provides one reference point, but it should be compared with the removed part and the valve manufacturer’s documentation before installation.
Potential Uses
The assembly may be suitable for maintenance or repair work on a compatible bathroom pressure balance valve. Common situations for considering a replacement internal valve assembly include a cartridge that no longer regulates water properly, a valve that requires internal service, or a repair where both the cartridge and balancing spool are being renewed at the same time.
- Replacing compatible internal components in a single-handle pressure balance valve
- Servicing a bathroom faucet or shower valve without replacing all visible trim
- Matching a cartridge and balancing spool supplied as one replacement set
- Using the listed dimensions to compare the replacement with an existing component
The product information does not confirm a particular faucet collection, trim style, installation method, or exact valve model beyond the stated application. Those details should be checked separately before work begins.
Compatibility and Installation Checks
Compatibility is the most important consideration for a replacement valve assembly. Before ordering or installing, compare the existing component with the listed dimensions and confirm that the replacement is intended for the same valve arrangement. Model documentation, the original cartridge, and the valve manufacturer’s parts information can help with this comparison.
- Confirm that the existing fixture uses a single-handle pressure balance valve.
- Compare the old cartridge and balancing spool with the listed 5 11/16-inch by 1 3/4-inch dimensions.
- Check the shape, connection points, stem arrangement, and retaining features against the replacement.
- Verify whether the existing valve requires separate seals, clips, screws, or other installation pieces.
- Shut off the water supply and follow appropriate plumbing procedures before removing internal parts.
Professional installation may be appropriate when the valve is difficult to access, the original parts are damaged, or the correct replacement cannot be confirmed. Forcing an incompatible cartridge into a valve body can damage internal surfaces or create leaks.
How It Compares With Other Replacement Options
Replacement valve components are commonly sold in several formats. A single cartridge may be appropriate when only that part requires service. A combined cartridge-and-balancing-spool assembly, such as this one, is intended for situations where both components are needed or where purchasing them together is more convenient.
Some replacement assemblies may also include check valves or additional components. Those versions should not be treated as interchangeable without confirming the valve design and required parts. The supplied product information confirms the cartridge and balancing spool, but it does not confirm check valves or other accessories for this specific assembly.
Frequently Asked Questions
What components are included?
The assembly includes a ceramic disc cartridge and a balancing spool. No additional accessories are confirmed in the supplied product details.
What valve is it intended for?
It is identified for a 1H pressure balance valve, meaning the stated application is a single-handle pressure balance valve. Exact compatibility should still be checked against the installed valve and its documentation.
What are the listed dimensions?
The listed dimensions are 5 11/16 inches by 1 3/4 inches. These measurements should be compared with the original component before installation.
Is the body made from brass?
The faucet body is listed as solid brass. The available details do not provide a complete material breakdown for every internal component.
Does the product include a faucet or trim kit?
No. The confirmed contents are the ceramic disc cartridge and balancing spool. A complete faucet, handle, trim, and additional installation hardware are not identified as included.

Final Thoughts
The Ceramic Disc Cartridge & Balancing Spool for 1H Pressure Balance Valve is a replacement assembly that combines a ceramic disc cartridge with a balancing spool for a stated single-handle pressure balance valve application. Its listed dimensions and solid brass faucet body construction provide useful points for comparison, while the included components help define the intended repair scope. Confirming the existing valve design, measurements, and required installation parts remains essential before replacing an internal plumbing component.
