Arrowhead Brass 221CCRBLF 1/2" MIP Lead-Free Brass Boiler Drain

The Arrowhead Brass 221CCRBLF is a 1/2" MIP boiler drain built in lead-free brass for rough-in and mechanical-room service on hydronic boiler systems, water heaters, and drain-down points where a compact, threaded quarter-turn shutoff is required. The 1/2" male iron pipe (MIP) connection threads directly into a standard 1/2" female iron pipe fitting for a straightforward, code-friendly installation into the mechanical piping run. As a "BLF" (brass, lead-free) designated part, this drain is intended for installations where lead-free brass construction is specified, giving plumbers and mechanical contractors a dependable option for boiler and system drain-down applications without needing to source a separate compliant fitting.

Key Features

  • Trade Size: 1/2" connection sized to mate directly with standard 1/2" iron pipe threaded fittings on boiler and hydronic piping runs.
  • Durable Construction: Lead-free brass body resists corrosion and provides long service life in mechanical-room and boiler-room environments.
  • MIP Connection: Male iron pipe threads allow the drain to be installed directly into a female-threaded boiler tapping, tank fitting, or system drain point without additional adapters.
  • Lead-Free Formulation: Manufactured to a lead-free (BLF) brass specification for use where lead-free fittings are called for on the job.
  • Compact Boiler Drain Design: Purpose-built as a boiler drain valve for system fill/drain, condensate, and low-point drain-down tasks on hydronic and heating equipment.

Arrowhead Brass 221CCRBLF – Frequently Asked Questions

1) Will the Arrowhead Brass 221CCRBLF thread into a 1/2 inch female tapping on my boiler?
Yes. The 221CCRBLF has a 1/2 inch male iron pipe (MIP) connection, so it threads straight into any standard 1/2 inch FIP tapping, tank fitting, or system drain point with no adapter or bushing.
2) Is this boiler drain lead-free for potable water work?
The 221CCRBLF is built in lead-free brass and carries a No-Lead standards designation, which is what the BLF in the model number refers to. That makes it the part to use where the spec or local code calls for lead-free brass on potable and system piping.
3) Can I use a boiler drain like this as a water heater drain valve?
Yes, that is one of its intended uses. Water heater and tank drain connections are commonly 1/2 inch female iron pipe, and the 221CCRBLF's 1/2 inch MIP body threads directly into that port for drain-down and flushing.
4) What is the difference between a boiler drain and a hose bibb or sillcock?
A boiler drain like the 221CCRBLF is a compact indoor drain valve for mechanical piping, fill and drain-down, and low-point drains on hydronic and heating equipment. A sillcock or hose bibb is an exterior wall valve with a long inlet shank and, in freeze climates, a frost-proof stem. If the valve is going through an outside wall, a boiler drain is the wrong part.
5) Do I need pipe dope or tape on the 221CCRBLF, and does anything else come with it?
The 221CCRBLF is supplied as the brass drain valve itself, with male iron pipe threads. Tapered pipe threads need a sealant, so plan on PTFE tape or pipe dope on the male threads. No adapters or bushings are required for a 1/2 inch FIP port.
6) Is a brass boiler drain durable enough for ongoing mechanical room service?
The body is brass, which resists corrosion in boiler and mechanical room conditions where a plated steel or plastic valve would suffer. For a property manager standardizing drain points across a building, the 1/2 inch MIP pattern keeps every drain-down connection the same part.
7) What is the exact part number to order this Arrowhead boiler drain?
Order Arrowhead Brass model 221CCRBLF. That is the manufacturer part number for the 1/2 inch MIP lead-free brass boiler drain, and the CCR-BLF suffix is what distinguishes the lead-free brass version from other 221 series drains.
