The BC / BD / BC-RN / BD-RN Series Branch Tee Fittings with Swivel Nut are designed to create three-way hydraulic tube connections while providing convenient installation through the swivel nut branch connection. The swivel nut enables quick assembly and simplifies maintenance by allowing tightening without rotating the tubing.

The BC and BD models provide standard branch tee connections, while the BC-RN and BD-RN versions incorporate an adjustable locknut structure, allowing orientation adjustment during installation to achieve the desired pipeline direction.
Manufactured with precision machining, these fittings provide secure hydraulic connections and dependable sealing performance under demanding operating conditions. Carbon steel and stainless steel material options are available, together with zinc-plated or other corrosion-resistant surface treatments to improve service life in industrial environments.
