Sioux Chief 118X206 Frostproof Sillcock 6.5 in Pex

Product Description

The SIOUX CHIEF 118X206 is a frostproof sillcock designed for exterior hose bib installations where freeze protection is required. The unit features a 6.5-inch freeze-protection depth, keeping the internal shutoff point well inside the thermal envelope of the building. The PEX connection inlet simplifies integration into modern PEX supply lines without additional adapters. This fitting is installed by licensed plumbers during new construction or retrofit projects on residential and light commercial buildings.

The 118X206 is suited for exterior wall applications where the supply line runs through an unheated space, such as a rim joist bay, crawlspace wall, or exterior framing cavity. The 6.5-inch barrel length provides adequate freeze protection in most climate zones when properly pitched for drainage. It connects directly to PEX tubing, making it a practical choice for plumbers working on PEX-based domestic water systems.

Key Features

• 6.5-inch frostproof barrel keeps the shutoff seat inside the building envelope
• PEX connection inlet for direct integration with PEX supply lines
• Frostproof design reduces freeze and burst risk in cold climates
• Standard hose bib outlet for garden hose or irrigation connections

Compatibility

Designed as an OEM-style replacement or new-installation frostproof sillcock for residential and light commercial PEX plumbing systems.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and the IPC. Shut off the domestic water supply and relieve line pressure before beginning work. The sillcock barrel must be pitched slightly downward toward the exterior so the valve drains completely when closed, which is essential for freeze protection to function as intended. Do not use thread sealants or connection methods incompatible with PEX fittings.
