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

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.
