XFITTING Pex A Expansion x GHT Hose Bibb Valve

The XFITTING PEX-A Expansion Hose Bibb is built for outdoor residential and light commercial plumbing where code compliance, freeze protection, and a secure PEX-A connection are required in one fitting.

The 1/2" F1960 expansion inlet connects directly to PEX-A tubing using standard expansion rings — no soldering, no crimp tools, no adapters needed. The built-in anti-siphon valve meets ASSE 1011, which satisfies the backflow prevention requirement for outdoor hose bibs in most US building codes, eliminating the need for a separate vacuum breaker.

When the hose is disconnected, the valve drains automatically to protect against freeze damage — critical for installations in unheated areas, crawlspaces, and exterior walls in cold climates.

All brass components are lead-free and NSF 61 certified for potable water contact. The mounting flange allows direct wall installation with a clean finished appearance.
