Dixon Valve Coupling B12SC Ground Joint Hose Coupling

Product Description

The DIXON VALVE COUPLING B12SC is a ground joint hose coupling designed for secure, leak-resistant connections in fluid transfer applications. Ground joint couplings use a machined male and female mating surface to form a tight metal-to-metal seal without requiring a gasket, making them well suited for steam, air, water, and general industrial hose service. This fitting is a standard trade-supply component installed by plumbers, pipefitters, and industrial maintenance technicians working on process lines, steam hose assemblies, and similar fluid handling systems. The B12SC weighs 0.96 pounds and ships as a single unit.

Ground joint hose couplings like the B12SC are used in both commercial and light industrial settings where a reliable, reusable hose connection is needed. Common applications include steam cleaning equipment, compressed air hose lines, water transfer hoses, and general-purpose industrial fluid service. The metal-to-metal seating surface allows the coupling to be broken and remade repeatedly without degrading the seal, which is a practical advantage in maintenance-heavy environments.

Key Features

• Metal-to-metal ground joint seating surface eliminates the need for a separate gasket
• Reusable design supports repeated connect and disconnect cycles without seal degradation
• Suited for steam, compressed air, water, and general industrial hose service
• Single-unit packaging allows individual replacement without minimum bulk purchase
• Weighs 0.96 pounds for straightforward handling during installation

Compatibility

Designed as an OEM-style replacement or direct-fit addition for industrial and commercial hose assemblies requiring ground joint coupling connections.

Installation Notes

Ground joint hose couplings are typically installed by licensed plumbers or pipefitters following applicable local mechanical and plumbing codes. Shut off and relieve pressure from the hose or line before removing or installing any coupling. Inspect the mating ground joint surfaces for nicks or scoring before assembly, as surface damage can prevent a proper metal-to-metal seal. Use appropriate wrenches sized to the coupling flats and avoid over-tightening, which can distort the seating surfaces.
