Arrowhead Brass 45504LF 45 Series Frost-Free Sillcock, Lead-Free Brass

Arrowhead Brass 45 Series Frost-Free Sillcock, Lead-Free Brass

The Arrowhead Brass 45 Series Frost-Free Sillcock is a lineup of standard and heavy-duty frost-free hydrants built in lead-free (LF) brass for rough-in and outdoor hose bibb installations where a plumber needs a reliable, code-conscious sillcock. This family page covers ten selectable models spanning the 455 and 459 model lines, including 455-04LF, 455-06LF, 455-08LF, 455-10LF, 455-12LF, 455-14LF, 459-04LF, 459-06LF, 459-08LF, and 459-12LF, giving contractors a range of barrel lengths to match different wall thicknesses and rough-in depths. Every model in the family shares the same frost-free operating principle and lead-free brass construction, so the choice between options comes down to matching the correct barrel length to the specific wall-through installation. Installers should confirm the exact barrel length and connection thread size for the selected model against the manufacturer's cut sheet or product packaging prior to rough-in.

Key Features

• Frost-Free Design: Every model in the 45 Series is engineered to drain residual water from the barrel after the valve is closed, helping protect against freeze-related failures in exterior wall installations.
• Lead-Free Brass: Built in lead-free (LF) brass across the entire family, suited for potable water supply applications where low-lead fixtures are specified by local code.
• Model Range: Available in ten configurations across the 455 and 459 lines — 455-04LF, 455-06LF, 455-08LF, 455-10LF, 455-12LF, 455-14LF, 459-04LF, 459-06LF, 459-08LF, and 459-12LF — covering a range of barrel lengths for different wall depths.
• Dual Series Platform: The 455 and 459 model lines share the same core frost-free, lead-free brass platform while offering distinct barrel-length options to fit varying rough-in requirements.
• Standard Configuration: Configured for typical wall-through hose bibb rough-in, rather than an anti-siphon or vacuum-breaker specialty variant.
• Professional Rough-In Use: Designed for installation by a licensed plumber or contractor as part of an exterior hose bibb or hydrant rough-in, not a decorative or finished-surface fixture.
