TZF Flanged Single Sphere Rubber Flexible Connector (TOZENFLEX)

The single sphere TOZENFLEX meets most design requirements for HVAC, process and industrial applications. When greater axial and transverse movements are required, the TWINFLEX product is recommended. All sizes are available with control sets. Refer to the Product Data Sheets for more information.
TOZEN single sphere Rubber Flexible Connectors are the most widely used rubber expansion joint. It provides a great degree of axial and transverse movement, meeting most piping system requirements. The standard product incorporates carbon steel flanged drilled to ANSI 150# specification.


Key Benefits

• Compensate for Axial and lateral movement due to thermal changes.
• Isolate noise and vibration from piping system.
• Floating flange drilled to mate with companion flanges for ease of installation.
• No gasket needed for sealing area.

Typical Application


Applicable to all piping systems connected to rotating equipment, such as pumps, chillers, cooling towers and condensers.

* Information in the above table is for single movement only. In case of complex movements, some correction is required as follows.

C.EL(C) =A.EL(C)X{1-( T.M. /A.T.M. + A.M. /A.A.M. )}

T.M. = Transverse Movement,
A.E. = Axial Elongation,
A.C. = Axial Compression,
A.M. = Angular Movement.
C.EL(C) = Correct Elongation (Compression)
A.EL(C) = Allowable Elongation (Compression)
A.T.M. = Allowable Transverse Movement
A.A.M. = Allowable Angular Movement
Install the joint according to the above given allowable dimensions.
