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.

Why Arrowhead Brass?

Arrowhead Brass manufactures its 45 Series frost-free sillcocks in lead-free brass, giving plumbers and contractors a straightforward, code-conscious option for exterior hose bibb rough-in work across a range of barrel lengths. The frost-free barrel design and lead-free construction reflect the practical, trade-focused engineering the 45 Series is built around, and the breadth of the 455 and 459 model lines makes it easier to match the right barrel length to the job, whether it's new construction or replacement of an existing hydrant behind the wall.

Arrowhead Brass 459-04LF – Frequently Asked Questions

1) How do I pick the right Arrowhead Brass 45 Series frost-free sillcock for my wall thickness?
Every model in the 45 Series works the same way, so the decision is purely barrel length against the depth of the wall you are going through. Ten models are orderable: 455-04LF, 455-06LF, 455-08LF, 455-10LF, 455-12LF, 455-14LF, 459-04LF, 459-06LF, 459-08LF and 459-12LF. Measure from the outside face of the finished wall back to where the supply line will tie in, then pick the model whose barrel covers that depth so the valve seat sits inside the heated space. Arrowhead advises checking the exact barrel length and connection thread for the model you choose against the manufacturer's cut sheet before rough-in.
2) Is the Arrowhead Brass 45 Series sillcock lead-free for potable water?
Yes. The whole 45 Series is built in lead-free brass, which is what the LF suffix on every model number signals, so it can be used on potable water supply where local code calls for low-lead fixtures.
3) What does frost-free actually mean on this hose bibb, and will it survive a freezing winter?
The 45 Series is a frost-free hydrant: the valve seat sits at the inboard end of the barrel, inside the heated wall, and the barrel drains the residual water back out once you shut the handle. Nothing is left standing in the exposed section to freeze and split it. That only holds if the hose is disconnected after each use, since a hose left attached traps the water in the barrel and defeats the drain.
4) Does the Arrowhead 45 Series sillcock come with a vacuum breaker or anti-siphon protection?
No. These are the standard frost-free configuration for ordinary wall-through hose bibb rough-in, not the anti-siphon or vacuum-breaker variant. If your jurisdiction requires backflow protection on an exterior hose connection, plan on a separate hose-connection vacuum breaker or specify an anti-siphon model instead.
5) What is the difference between the Arrowhead 455 and 459 model lines?
Both lines sit on the same frost-free, lead-free brass platform and differ in the barrel-length options offered. The 455 line runs through six choices (455-04LF, 455-06LF, 455-08LF, 455-10LF, 455-12LF and 455-14LF), including the longest barrel in the family, while the 459 line offers four (459-04LF, 459-06LF, 459-08LF, 459-12LF). Arrowhead describes the 45 Series as covering both standard and heavy-duty frost-free hydrants, so match the model designation on the spec or the unit you are replacing rather than assuming the two lines interchange.
6) Can I use this to replace an existing frost-free hydrant behind a finished wall?
Yes, replacement of an existing frost-free hydrant is one of the intended uses, along with new-construction wall-through rough-in on residential and light commercial work. For a swap, read the model number off the old unit or measure its barrel and match a 45 Series model of the same length, and check the connection thread size on the cut sheet so it mates with the supply stub you already have in the wall.
7) I need to standardize hose bibbs across a multi-building property. Does the 45 Series cover different wall depths with one product family?
It does. All ten models share the same frost-free operating principle and lead-free brass body, so the trim, handle style and repair approach stay consistent across the portfolio while you vary only the barrel length by building, from the 04 models up to 455-14LF. That keeps one spare-parts approach across sites instead of mixing brands per wall thickness.
8) Can a property maintenance tech install an Arrowhead 45 Series sillcock, or does this need a plumber?
These are rough-in hydrants meant to be installed by a licensed plumber or contractor as part of an exterior hose bibb or hydrant rough-in. It is not a surface-mount decorative fixture, the barrel passes through the wall and the valve body ties into the supply line inside, so it usually means opening the wall or working from a basement or crawlspace.
