CERAMA RTC HOT W/ CHECK & HDL

CERAMA RTC HOT W/ CHECK & HDL is a hot-water ceramic faucet cartridge assembly used in commercial-style faucets (commonly T&S Brass style fixtures).

Product Description

This part is the hot-side (RTC = Right-to-Close / Hot) version of a Cerama quarter-turn cartridge and typically includes:

• Cerama ceramic disc cartridge (hot water side)
• Check valve to prevent cross-flow between hot and cold lines
• Lever handle connection (HDL = handle/lever assembly interface)
• Red index marking (usually indicates HOT side)

What it does

• Controls hot water flow and temperature in a faucet
• Uses a quarter-turn ceramic mechanism for smooth on/off operation
• The check valve prevents backflow, helping avoid mixing hot and cold water inside the body

Common applications

• Commercial lavatory faucets
• Institutional sinks (schools, hospitals, restaurants)
• T&S-style faucet systems using replaceable cartridges

In simple terms

It’s the replaceable hot-water valve core + handle connection piece that lets you turn hot water on/off smoothly while preventing water cross-over inside the faucet.
