Technical Specifications
Dry Disconnect Connection Configuration
The bayonet-style coupler connects with a compatible dry disconnect adapter and incorporates the operating mechanism used to control fluid transfer.
The straight swivel body terminates in a female NPT connection for attachment to compatible threaded piping or transfer equipment.
Bayonet Dry Disconnect Coupler Design
Dixon designs its bayonet dry disconnect system for spill-reducing transfer of petroleum products including fuel oil, lube oil blending, and tank-truck delivery. The connection is intended to reduce product loss during coupling and uncoupling.
The internal valve arrangement prevents fluid flow until the mating components are connected and the valve is opened. The coupling cannot be disconnected again until the valve handle has been closed.
The BSS-Series uses a straight swivel body with a female NPT outlet. The swivel allows connection to compatible piping while helping reduce hose or piping twist during installation and service.
Dixon identifies the straight swivel configuration separately from the fixed straight BC-Series and the 90° swivel BS-Series. Verify that the straight-swivel layout is correct for the installation before ordering.
Dixon offers the 2" BSS straight swivel coupler as BSS61-200 with Buna/NBR seals and BSS62-200 with FKM seals. The correct seal should be selected according to the transferred product and operating conditions.
Do not assume the seal material from the coupler size alone. Verify the exact part number and media compatibility before placing the coupler into service.
Dixon specifies a maximum operating pressure of 85 PSI at 70°F for its bayonet-style dry disconnect fittings. For pressure ratings at other temperatures, Dixon recommends contacting the manufacturer.
The bayonet coupler is interchangeable with compatible Emco Wheaton™ Dry Break™ equipment. Confirm mating-component compatibility, pressure requirements, seal material, and connection size before installation.
