User Manual

STUF IS A FILLER; Specifically formulated for use in connectors used on coaxial cables. It is formulated to
simulate the dielectric properties of foam polyethylene (common coaxial cable core).
Directions: Mate tube of STUF to connector cap end and fill.
Thread connector and snug with wrench, A resistance to
tightening should be noted as STUF is channeled into voids
Ultimate signal throughput performance will be realized
after STUF fluids migrate, (one week), forming a moisture
impermeable, clay like , Teflon - Silica compound.
Filling volume is a "pea" sized for smaller f-connector sizes
and 2 - 3 "peas" for larger connectors: PL,UHF,N, BNC,TNC
type connectors. The STUF volume applied should be twice
the estimated void volume after the connector is assembled
Depositing a proper fill amount of STUF is most easily done upon the center conductor of the
“Cap” side of the connector assembly. When assembled and tightened; STUF is compressed,
channeled into internal voids, reducing it's volume as the glass microspheres and teflon particles
pack and the oils extrude into threads, machined borders and the cable braid area
Opening up the connector for inspection should show STUF deposited
in the interior of the connector in a circular symmetrical fashion ( see pic
at right ). Inspection should be done any time a new type of connector is
used to verify proper fill volume & full Seating of the connector.
To Reassemble : Deposit +/- ½ pea of STUF again on the center
Note on N Connectors: ( Rubber back sealed ) Connectors: (Photo down right)
Some connectors use a true mating seal within the connector. This seal can
stop the extrusion of STUF into the rear area of the connector and through
the parts borders.
In these types of connectors ; it is recommended to check the connector
( Open Up ) and verify a circular mark on the inner rubber seal face to verify
the connector fully seated when filled and assembled.
This does not apply to f - style connectors with "O" Rings
How to Use S.T.U.F. : Silica, Teflon, Unionizing, Filler
STUF on BIC Pen
Note: Microspheres
Correct STUF fill volume should be +/- Twice the
estimated internal void volume when assembled.
Oily STUF: Some product separation of the oils always occur. This separation will
not effect STUF performance. In excessive cases : Manipulate the cap closed tube
to re-mix the oils into the solids within the tube.
