Boltigen 10" Frost-Free Anti-Siphon Sillcock — Lead-Free Brass Outdoor Faucet, 1/2" Push-To-Fit x 3/4" GHT

Boltigen's 10-inch frost-free anti-siphon sillcock is a lead-free brass outdoor faucet that prevents freezing and backflow while giving a quick 1/2" push-to-fit inlet and a 3/4" GHT hose connection.

Built for cold climates and straightforward installs, this frost proof outdoor faucet combines a long 10" stem with an internal anti-siphon mechanism to reduce freeze risk and protect potable water from backflow. Its chrome-plated, lead-free brass body resists corrosion, and the flexible push-to-fit inlet makes connecting to PEX, CPVC, PE-RT, or copper fast and secure. The outlet uses a standard 3/4" GHT hose bibb thread so it works with most garden hoses and watering accessories.

How does this sillcock stop pipes from freezing in winter?

The 10-inch stem positions the shutoff valve well inside the heated wall cavity so residual water drains away from the exterior spout, lowering freeze risk. The frost-proof design uses a long-stem valve arrangement rather than relying on insulation alone.

• 10" stem keeps the valve inside warm space
• Internal valve drains water from the exterior section
• Chrome-plated brass endures outdoor exposure

What makes the anti-siphon feature important for outdoor faucets?

The anti-siphon function prevents contaminated water from being drawn back into your home supply during drops in pressure, maintaining water safety. It's a passive backflow prevention built into the sillcock so compliant protection is automatic.

• Built-in anti-siphon prevents backflow contamination
• Works without additional external backflow devices
• Helps meet code requirements for potable water safety

Can I install this without special fittings or tools?

The 1/2" push-to-fit inlet enables quick, tool-free connections to common pipe types for many installations. If you need a threaded connection instead, remove the push-fit sleeve and the inlet converts to a 1/2" NPT male thread for conventional fittings.

• Push-to-fit attaches to PEX, CPVC, PE-RT, and copper
• Removable portion converts to 1/2" NPT male thread
• Standard 3/4" GHT outlet for common hoses and accessories

What materials and durability features does this faucet offer?

The sillcock is manufactured from lead-free brass with a chrome finish to balance safety for drinking water and resistance to outdoor corrosion. The materials and design are chosen to handle repeated seasonal use and the stresses of hose connections.

• Lead-free brass body for potable water safety
• Chrome plating for enhanced corrosion resistance
• Robust hose bibb thread to reduce wear at the outlet
