Boshart BF-41S Short Milled Flare Nut Fitting, Non-Gas Plumbing

The Boshart BF-41S Short Milled Flare Nut is a rough-in fitting component designed for use with flare-style tube connections in plumbing and heating applications, available in 3/8\" and 1/2\" sizes to cover common rough-in tubing dimensions. Flare fittings of this type are engineered to work with aluminum, brass, copper, and steel tubing and are built to be disassembled and reassembled multiple times without compromising the seal at the flare joint. This particular flare nut is a short, milled design and is specifically NOT intended for use on gas or fuel applications — installers should limit this fitting to non-gas, non-fuel plumbing and heating lines only. Across both the 3/8\" and 1/2\" sizes, the fitting shares the same short milled profile, flare-style sealing method, and tubing compatibility, making it a versatile stocking item for contractors who need a compact flare nut option across multiple rough-in tubing diameters.

Key Features

  • Trade Sizes: Offered in 3/8\" and 1/2\" sizes to match common flare-tube rough-in dimensions found in plumbing and heating installations.
  • Flare-Style Connection: Designed to mate with flared tube ends for a mechanical seal that can be broken down and reassembled repeatedly without loss of sealing performance.
  • Short Milled Profile: A compact, short-body milled nut design suited for tight rough-in spaces where a standard-length flare nut will not fit, available across both offered sizes.
  • Broad Tubing Compatibility: Flare fitting technology of this style is commonly used with aluminum, brass, copper, and steel tubing across plumbing and heating installations.
  • Not for Gas or Fuel Applications: This specific flare nut is restricted to non-gas, non-fuel plumbing and heating uses only — do not install on gas or fuel supply lines.
  • Reusable Design: Flare connections can be taken apart and reconnected many times over the life of the installation without degrading the joint seal.

Technical Specifications

  • Available Sizes: 3/8\", 1/2\"
  • Country of Origin: China
  • Prop 65 Warning: Lead
  • Packaging: 25 ea

Boshart BF-41S-06 – Frequently Asked Questions

1) Can the Boshart BF-41S flare nut be used on a natural gas or propane line?
No. The BF-41S short milled flare nut is restricted to non-gas, non-fuel plumbing and heating lines. Do not install it on gas or fuel supply piping. For water and hydronic heating tubing runs it is in scope; for fuel gas you need a fitting rated for that service.
2) Is a flare nut all I need, or do I need another part to make the joint?
A flare nut is one half of the connection. The BF-41S nut captures the flared tube end and pulls it onto the cone of a mating flare fitting or the flare seat on a valve or appliance, so you also need that mating half plus a flaring tool to form the tube end. Order the nut in the size matching your tubing, 3/8 or 1/2 inch.
3) What sizes does the Boshart BF-41S short milled flare nut come in?
Two trade sizes, 3/8 inch (BF-41S-06) and 1/2 inch (BF-41S-08). Both share the same short milled body and flare sealing profile, so the only decision is matching the nut to the outside diameter of the tubing you are flaring.
4) Will a flare nut work on copper and aluminum tubing, or only copper?
Flare connections of this style are used with aluminum, brass, copper, and steel tubing, so the BF-41S is not limited to copper. The tube end has to be properly flared with a flaring tool first, the nut slides on behind the flare and draws it against the mating fitting's cone.
5) Why choose a short milled flare nut instead of a standard-length one?
The short body is for tight rough-in spaces where a full-length flare nut will not turn or will not clear an adjacent wall, stud, or fitting. Sealing method is identical, it is purely a clearance choice. If you have room, a standard-length nut works the same way.
6) Can I take a flare joint apart and put it back together?
Yes. That is the main advantage of a flare over a soldered or compression joint. The BF-41S can be disassembled and reassembled repeatedly without degrading the seal at the flare, provided the flared tube end itself is not damaged or cracked. Useful on serviceable equipment connections and valve changeouts.
7) Does the Boshart BF-41S carry a Prop 65 warning?
Yes, the BF-41S carries a California Prop 65 warning for lead. Institutional and municipal buyers specifying potable water fittings should factor that into their submittal review. Country of origin is China.
8) How many flare nuts come in a pack from Boshart?
The BF-41S is packaged 25 each, which makes it a practical stocking item for a plumbing or heating shop that runs both 3/8 and 1/2 inch flare joints rather than buying onesies per job.
