Boshart BF-46 Flare x FIP Brass Coupling

Boshart BF-46 Flare x FIP Brass Coupling

The Boshart BF-46 is a flare-by-female-iron-pipe (FL x FIP) brass coupling built for rough-in plumbing and heating tie-ins where a flared tube connection needs to transition to a threaded fitting. This coupling family is available in sizes ranging from 3/8" x 3/8" up to 1/2" x 1/2", including a 3/8" x 1/2" transition option, giving installers a fitting sized to match the exact tubing-to-pipe transition on the job. It is suitable for gas, oil, air, and water lines and mates with aluminum, brass, copper, and steel tubing, making it a versatile choice for service techs and installers working across multiple pipe systems. A key advantage of flare fittings is that the flare joint can be disassembled and reassembled multiple times without degrading the seal, which is valuable for equipment that requires periodic service access such as water heaters, gas appliances, and HVAC connections. Couplings ship 25 pieces per package, making this a practical stock item for shops and service trucks that install these connections regularly.
