STUF Silica PTFE 3.2 Cubic Inches Unionizing Filler

  • Prevents Moisture Infiltration by Occupation
  • 3.2 Cubic Inches per tube


An Ultra-low Density, All Dielectric Filler Specifically Formulated to Simulate Coaxial Cable Core.

Many Coaxial connectors are poorly  designed and contain air pockets which allow a “ breathing” of the connector with changes in ambient temperatures.

Directions: Mate tube of STUF with connector cap end and fill. Thread connector and snug with wrench. A slight resistance to tightening should be noted as STUF is channeled into voids.

STUF Factoids:

  • STUF is a pure dielectric compound: It is inert to electromagnetics (Dielectric ); Put a blopin a microwave oven, it will not even get warm.
  • STUF has a dielectric constant simulating the most common coaxial cable core used in residential coax :Polyetyelene Foam , <- 1.5
  • STUF is non-frequency dependent: From shortwave to microwave it responds the same to the signal energy.
  • STUF contains corrosion inhibitors which crawl into the cable braid and connector body to control corrosion.
  • STUF will not interfere with electrical throughput in powered cables: stuf is  highly extrudeable and is forced, like air, away from metal to metal contacts.
  • STUF will stop migration of flooded cable fluids into connector voids, which causes high return ( reflection ) losses in flooded cable assemblies.
  • Factory box is 50 pieces.
