Frost Proof Sillcock 8 In

The Zoro Select 104-403 is a frost proof sillcock designed for outdoor water supply connections. It features a chrome plated brass body rated for a maximum pressure of 125 psi. The inlet accepts a 1/2 in solder cup or MNPT connection. An aluminum handwheel handle operates the valve.

Anti Siphon Protection Standards

The unit incorporates an anti siphon mechanism to prevent backflow contamination of the potable water supply. It complies with ANSI B 1.20.1, ANSI B 16.18, and ANSI B 1.20.7 standards. The frost proof design protects the valve from freezing damage when installed correctly through a heated wall. California Proposition 65 warnings apply for cancer and reproductive harm.

Installation Ready Components

The sillcock ships as a complete assembly with the handle and anti siphon components factory installed. No separate cartridges or repair kits are included in the package. The 8 in length determines the wall thickness range the unit can span. Buyers needing a different stem length or a vacuum breaker certified to other local codes cannot use this model.

Questions about this item

How do I install the Zoro Select 104-403 sillcock with a 1/2 in solder cup inlet, and what step is often missed?

Clean and flux the copper pipe, then sweat the solder cup joint; the step often missed is angling the valve body slightly downward so water drains out and the frost-proof function works.

Which parts of the 104-403 sillcock will need replacement over time?

The internal stem washer and vacuum-breaker seal typically wear first; both are serviceable without removing the valve body from the wall.

At what pressure does the 125 psi rated sillcock reach its limit during sustained use?

The valve is rated for 125 psi maximum working pressure; sustained operation above that pressure risks seal failure and body distortion.
