Boshart FHBBARB Series Barb x Threaded Brass Adapter Fitting

Boshart FHBBARB Series Barb x Threaded Adapter Fitting

The Boshart FHBBARB Series is a line of barb-to-threaded transition adapters built for plumbers and contractors who need a fast, reliable connection between barbed tubing and threaded pipe fittings in rough-in, repair, and frost-free hydrant applications. This family covers configurations from a straight 3/4" barb x 3/4" FPT adapter (FHB-BARBXFPT121) to a 90° barb x MPT elbow adapter (FHB-BARB90XMPT0), giving installers a barb-to-thread transition option whether they need a straight run or a directional change. Across the line, one end features a barbed connection for push-on tubing attachment while the opposite end is threaded — either female iron pipe thread (FPT) or male iron pipe thread (MPT) depending on the option selected — for connecting directly to a threaded fitting, valve, or hydrant body. These adapters are intended to be installed by a trade professional as part of a larger supply or hydrant assembly rather than as standalone consumer fixtures.

Key Features

• Trade Size: 3/4" barb by 3/4" threaded connection sized to match standard 3/4" hydrant and supply-line hardware.
• Barb x Threaded Configuration: One end features a barbed connection for push-on tubing attachment; the threaded end is available as FPT (straight) or MPT (90° elbow) depending on the model selected.
• FHBBARB Series: Part of Boshart's FHBBARB line of barbed adapter fittings, engineered to work alongside compatible frost-free hydrant and rough-in plumbing components.
• Straight and 90° Options: Choose the straight barb x FPT adapter for in-line transitions or the 90° barb x MPT adapter when a directional change is needed within the assembly.
• Rough-In Application: Suited for use behind walls, underground, or in exterior hydrant assemblies where a barb-to-thread transition is needed to complete the run.
• Single-Fitting Simplicity: A single compact adapter reduces the number of transition pieces needed when tying barbed tubing into a threaded system.
