Flexible assembly for sprinklers

An assembly for connecting a sprinkler to a branch line of a fire suppression system, said assembly comprising:

• a flexible conduit having a first end connectable to said branch line, and a second end connectable to said sprinkler, said conduit providing fluid communication between said branch line and said sprinkler;
• a first adapter having a first adapter portion attachable to said branch line and a second adapter portion attached to said first end of said conduit, said first and second adapter portions being rotatable relatively to one another, said first adapter having a bore providing fluid communication between said branch line and said conduit;
• a second adapter positioned between said sprinkler and said second end of said conduit for effecting attachment of said conduit to said sprinkler, said second adapter having a bore providing fluid communication between said sprinkler and said conduit;
• a bracket having an opening receiving said second adapter and a locking unit movably mounted on said bracket, said locking unit engaging and retaining said second adapter within said opening;
• a cross beam received by said bracket for securing said bracket in relation to said branch line;
• and
• said second adapter portion comprises a tube attached to said first end of said conduit, said tube being received within said bore of said first adapter in said first adapter portion;
• a ring seal is positioned between an outer surface of said tube and an inner surface of said bore in said first adapter portion for effecting a fluid-tight connection between said first and second adapter portions;
• a split ring is positioned between said outer surface of said tube and said inner surface of said bore in said first adapter portion, said split ring having an inner portion sized to fit within an outwardly facing circumferential groove positioned in said outer surface of said tube, said split ring further having an outer portion sized to fit within an inwardly facing circumferential groove positioned in said inner surface of said bore in said first adapter portion, said split ring preventing relative axial movement between said first and second adapter portions but permitting relative rotation between said first and second adapter portions about a longitudinal axis concentric with said bore of said first adapter.
