Use Filler to Control Movement, Not as a Substitute for Fit
A correctly selected tube profile controls the device across its critical body and lead geometry. Filler addresses the remaining longitudinal void or, in some special configurations, provides an additional support element. It should not be used to force an otherwise incompatible device into a profile.
Many fillers can be cut to the required working length. Confirm the actual tube length, device count and closure arrangement before establishing the filler length.
Tube profileThe filler cross-section must be compatible with the cavity and the way the device is supported.
Working lengthDetermine the unused internal length after the devices and end closures are accounted for.
Material requirementUse the exact product suffix, product data and application requirements to select the appropriate filler construction.
Common Tube-Filler Applications
Partial tube loadsOccupy unused length so devices are not free to travel from one end closure to the other.
Special loading arrangementsSupport application-specific configurations when a standard tube profile needs an additional controlled element.
Cut-to-length useEstablish the working length from the actual device quantity, tube length and closure placement.
