Single Filled Arch Expansion Joint
Single Filled Arch Expansion Joint has all the functional characteristics of open arch expansion joints and additionally, with filled arch
construction, it prevents the collection of solid materials that may
settle and remain in the archway.
The Onyx Expansion Joints reduce and isolate vibration, noise transmission and compensate movements in alignment due to wear and
load stresses.

DFA TFA
and
Multiple Filled Arch Expansion Joint
• DFA ( Double Filled Arch )
• TFA ( Triple Filled Arch )
Multiple Filled Arch Expansion Joint, with two or three filled arches,
is recommended for greater movement capability for expansion and
contraction where face-to-face dimensions are not limited.
With filled arch construction, it prevents the collection of solid materials that may settle and remain in the archway.
The Onyx Expansion Joints reduce and isolate vibration, noise transmission and compensate movements in alignment due to wear and
load stresses.

Technical Information
CONTROL ROD
The flexible rubber sleeves of expansion
joints, filled arch or open arch construction
must be installed in piping systems that are
properly anchored so that the flexible sleeves
may not be subjected to compression or elongation of piping movement.
B
If axial forces can act in the system to compress or elongate the rubber sleeve, control
rods units will be required to prevent axial
movement. In general, control rods units are
always recommended as an additional safety
factor, preventing damage to the rubber
sleeve and associated equipment.
