Boshart BF-48 Flare x MIP Half Union Fitting, Brass Construction

Boshart BF-48 Flare x MIP Half Union Fitting, Brass Construction

The Boshart BF-48 is a 3/8" x 3/8" flare half union fitting with a flare end connecting to a male iron pipe (MIP) threaded end. This half union is part of a family of flare-to-thread transition fittings offered in 1/2" x 1/2", 3/8" x 3/8", and 3/8" x 1/2" sizing, giving installers flexibility to match tubing and pipe-thread combinations across a range of plumbing and heating jobs. Flare fittings like this one are used across plumbing and heating trades for gas, oil, air, and water line connections, and this fitting is applicable with aluminum, brass, copper, and steel tubing. A key advantage of a flare connection is that it can be disassembled and reassembled many times without affecting the seal, which makes it a practical choice for service work, appliance hookups, and rough-in runs where a line may need to be broken down for maintenance or future modification. This half union design allows a plumber or HVAC technician to transition cleanly from flared tubing to standard male-threaded pipe or fittings, simplifying connections at valves, regulators, manifolds, and appliance stub-outs. Each unit ships in a case pack of 25, making it well suited for stocking trucks, supply houses, and job sites that run through this connector size regularly.
