Resi-Mizer Injectors QC-1 through QC-5 belong to the group known
as Progressive Screws. These injectors are shaped like a threaded
cone and work with a gasketing sleeve. The sleeve fills irregularities
or rough spots in the concrete. The user pushes the sleeve and the
tip of the injector into the drill hole until the top of the sleeve
is flush with the surface of the concrete. With a light tap of the
wrench, the sleeve bites into the concrete and sticks snugly. Then
the injector can be wrenched or ratcheted through the sleeve to
Resi-Mizer Injectors in the progressive screw group share many advantages
and are very popular. They seal tightly, quickly and reliably even
at gauge pressures of several thousand psi. They are inexpensive;
some are discardable after only one use. They are also tough enough
to use more than once, some of them over and over. Even the plastic
versions can handle high pressures and have been tested in steel
blocks to 10,000 psi.
Resi-Mizer Injectors in the progressive screw group
can be installed and removed very quickly with gloves on. The metal
versions are easy to clean, When injection is finished, they can
be reversed out of the hole, cut off flush, driven in, or drilled
out as the applicator desires or the application requires. Progressive
screw injectors have wide flow paths with excellent flow-through.
Most can be used with any injectable material. These injectors also
support a wide variety of hose connections, including zercs, button
heads, Hansen-type quick-connects, needles, and NPT threaded connections
in 1/8" and 3/8" sizes.
All progressive screw Resi-Mizer Injectors are packaged
and shipped with a gasketing sleeve. Extra sleeves may be ordered
separately for reusable injectors to replace sleeves lost or damaged
in field use.
