This guide is for homeowners and DIY enthusiasts looking to repair or replace faulty faucet valves. The key benefit is restoring smooth operation and preventing leaks in bathroom and kitchen taps using durable brass cartridges. A caveat is ensuring correct measurement and spline count before purchase. This product is a pair of quarter-turn ceramic disc cartridges, suitable for hot and cold water, featuring solid brass construction, G 1/2" BSP thread, and a 20-tooth spline for handle attachment.

A quarter turn means the faucet handle only needs to be rotated 90 degrees (a quarter of a full circle) from the off position to the fully open position, unlike older faucets that require multiple turns.
The Red stem is typically for clockwise rotation (to turn on), usually associated with the hot water line. The Blue stem is for anti-clockwise rotation (to turn on), usually for the cold water line. Your faucet handle's design will dictate which way it needs to turn.
Yes, you can use either the Red or Blue stem individually for either hot or cold lines, depending on which one needs replacement. However, the product is sold as a pair.
The spline is the serrated (toothed) part at the top of the stem that engages with the faucet handle, allowing the handle to securely turn the valve stem.
Ceramic disc cartridges are known for their durability and can last for many years, often outlasting the faucet body itself, provided they are used with relatively clean water and operated correctly.
G 1/2" BSP refers to a standard pipe thread size. 'G' indicates a straight (parallel) thread, and '1/2"' is the nominal size. This is a common thread standard in many plumbing fixtures.
Plumber's tape (PTFE tape) is typically not required for installing the cartridge itself into the faucet body, as the seal is made by the O-ring and threaded collar. It may be used on the connections for the water supply lines if they are being disturbed.
Ensure the correct cartridge (Red/Blue) is used for hot/cold. Check that the cartridge is fully seated and the retaining nut/collar is tight. Verify the faucet body is clean and free from debris. The faucet seat may also be damaged and require repair or replacement.
Confirm the handle is correctly aligned with the 20-tooth spline on the stem. Ensure the threaded collar is not overtightened, which can bind the mechanism. Check for any obstructions in the faucet body.
The O-ring or threaded collar might not be properly sealed. Ensure the O-ring is intact and the collar is tightened sufficiently. If the leak persists, the faucet body itself may be compromised.
Double-check the thread size (G 1/2" BSP) and the spline count (20 teeth). If these do not match your faucet, you have the incorrect cartridge. Measure carefully and consult your faucet's manual if possible.
