In-Weg ® Internal Joint Sealing
Creamer In-Weg ® seals are designed for the internal sealing of leaking pipe joints or cracks in all
types of pipe materials, including cast iron, ductile iron, concrete, reinforced concrete, steel, vitrified
clay and plastic piping systems having pipe diameters of 16 inches or larger.
Creamer In-Weg ® seals permanently eliminate leaks at internal pressures up to 300 psi. Excavations
for access can be as much as 5,000 feet apart, causing very little disruption to traffic and greatly
reducing restoration cost.
Creamer In-Weg ® seal incorporates three lip seals
on each outer edge which completely seal the
circumference of the pipe on either side of the leaking
joint or crack. The flexibility of the Creamer In-Weg ®
seal ensures a bottle-tight seal around the entire pipe
joint, while its low profile and graded edge allow the
product to flow without creating noticeable turbulence.
Creamer In-Weg ® seals offer an economical and
trenchless alternative to conventional repair methods.
Manufactured in the USA, over 50,000 seals have
been successfully fitted worldwide.
A range of Creamer In-Weg ® seal widths are
available for use on a variety of joint gaps. The
seals are locked into place by carbon steel,
stainless steel or composite retaining bands
depending on the application. Creamer In-Weg ®
seals can also be used in conjunction with
specially manufactured sleeves to permanently
repair longer cracks, pipe reducer fittings,
complete pipe lengths or even seal off abandoned
branches and service connections. Creamer
trained and certified installation technicians
perform all work in strict accordance with
O.S.H.A. standards for confined space entry.

Water/Waste Water
A non-toxic EPDM (Ethylene Propylene
Diene Monomer) synthetic rubber compound
is used to manufacture seals for potable
water, raw water and sewage pipe
applications. The stainless steel retaining
bands are made from the appropriate alloy
for each particular application.

In-Weg ® Applications
Natural Gas
Seals designed for natural gas
piping are manufactured from a
nitrile (butadiene acrylonitrile)
rubber compound. Carbon steel
retaining bands are made of the
appropriate alloy for each
particular application.
“Our field personnel established a
wonderful working relationship with
the folks from J. Fletcher Creamer
& Son, Inc. They worked safely,
professionally and did what they
needed to do to get the job done
without disrupting our everyday
maintenance functions. We welcome
the opportunity to work with the JFC
organization again in the future.”
Industrial Applications
William Mowell
Chief Engineer
Village of Ridgewood, NJ
Seals designed for use in industrial pipe
lines are manufactured from the
appropriate rubber compound to insure
chemical and corrosive resistance. The
retaining bands can be made from any
appropriate metal alloy or composite
material. Creamer engineers can help
choose the correct materials for use in
any industrial application.

Installation Procedure
The joint area is cleaned and prepared prior to the
installation of the seal. This may be achieved by using
a variety of hand or pneumatic tools.
An expansion ring is placed over each retaining
band and pressure is applied radially. A correctly sized
wedge is inserted between the band ends to keep a
permanent compressive force on the seal.
The completed seal provides a permanent solution
to leaking pipe problems. A completion report is
supplied detailing the type and location of each seal
and any other repair carried out in the pipe.
A non-toxic lubricating soap is applied and the seal
is carefully positioned with its retaining band.
Each seal is leak tested twice before the main is
put back into service.
