MILLENNIUM CC54405ZX Angle Stop

The MILLENNIUM CC54405ZX is a compression angle stop connecting a 5/8 inch OD supply line to a 1/2 inch OD outlet. It is intended for residential or light commercial plumbing installations where a shut-off valve is required at the fixture supply point.

Sustained pressure reliability

The valve body is designed to maintain a positive seal under continuous household water pressure. Internal components resist degradation from mineral content and temperature cycling typical of daily hot and cold water service over extended periods.

Installation and compliance notes

The brass construction handles normal thermal expansion without distortion or leakage at the compression joints. California Proposition 65 warnings apply because the product contains chemicals identified by the state as causing cancer and reproductive harm.

Questions about this item

Does the CC54405ZX angle stop generate noise, heat or draw power when left open all day?

No, the CC54405ZX is a purely mechanical valve with no electrical components, so it produces no noise, heat or power draw during continuous use.

What existing plumbing must I already have to install the CC54405ZX angle stop?

You need a 5/8 inch OD copper or supply tube for the inlet and a 1/2 inch OD tube for the outlet, both prepared for compression fittings.

Will the CC54405ZX work with older 5/8 inch and 1/2 inch compression supply lines I want to keep?

Yes, the CC54405ZX uses standard compression threads for both sizes, so it connects directly to existing 5/8 inch and 1/2 inch OD supply lines without adapters.
