Boltigen frost-free sillcock freeze-proof outdoor faucet 10-inch stem, lead-free brass & 3/4" GHT

Boltigen 10-inch freeze-proof outdoor faucet is a lead-free brass frost-free sillcock with a 1/2" PEX connector and 3/4" GHT hose bibb designed to keep outdoor plumbing from freezing while providing a secure hose connection.

This frost-proof sillcock from Boltigen combines a long 10-inch stem, lead-free brass construction, and a 3/4" garden hose thread outlet to deliver a durable outdoor spigot for homes and light commercial use. It installs quickly to PEX piping using ASTM F1807-compliant fittings and incorporates anti-siphon design features to help prevent backflow. Finished in chrome plating, the faucet resists corrosion and is suitable for potable water applications where freezing conditions are a concern.

How does the 10" stem protect plumbing in cold weather?

The extended 10-inch stem positions the shutoff valve deeper inside the heated wall cavity so water remaining in the exterior portion drains away from freezing zones. That distance reduces the chance of ice forming in the outdoor portion and minimizes freeze-related bursts. The sillcock’s internal valve is designed to close well inside the building envelope where temperatures are more stable.

• 10-inch stem keeps shutoff inside warmer space
• Interior valve closure reduces exterior standing water
• Chrome-plated brass resists corrosion in freeze cycles

What connections are included and how do they install?

The Boltigen frost-free spigot features a 1/2" PEX connector compatible with ASTM F1807 crimp or clamp fittings and a 3/4" GHT (garden hose thread) outlet for standard hoses. Installation involves securing the sillcock to the exterior wall, attaching the PEX fitting, and tightening the hose thread for accessory use. The PEX end simplifies retrofits and new builds alike.

• 1/2" PEX end conforms to ASTM F1807 standards
• 3/4" GHT hose bibb for universal hose attachment
• Threaded outlet allows quick accessory hookup

Is the faucet safe for drinking water and long-lasting?

Boltigen’s sillcock is made from lead-free brass with a polished chrome finish, making it suitable for potable water systems and offering extra corrosion resistance. The materials and construction are selected for outdoor exposure, giving dependable service life when properly installed and winterized. Anti-siphon features help reduce the risk of backflow into the supply.

• Lead-free brass for potable-water safety
• Chrome plating improves corrosion resistance
• Anti-siphon design helps prevent backflow

How does this sillcock fit common outdoor uses?

This frost-free spigot is intended for yard hoses, irrigation hookups, and general outdoor water access where freezing is a concern. The ergonomic hose bibb makes attaching and removing hoses smoother and reduces wear on threads. It works well for seasonal watering, pressure washers, and any application that needs a dependable exterior water point.

• Ideal for garden hoses, irrigation, and hose accessories
• Ergonomic discharge reduces hose wear and leaks
• Suitable for residential and light commercial outdoor use

It’s a practical choice when upgrading outdoor plumbing to PEX or replacing older sillcocks, especially in regions that experience winter temperatures that can damage exterior fixtures.
