The Dri-Seal range of products has been developed as a
cost-effective means to enhance the longevity of both
shell &
tube and
air-blast heat exchangers. Our product range currently
comprises of:-
Dri-Seal Jiffi-Plug
- the safest and most convenient method of plugging failed heat
exchanger tubes
Dri-Seal Façade
Tubeplate Protection System - for cost effective life
extension of eroded or corroded heat exchanger tubeplates
Dri-Seal Tube Insert
- protect the ends of heat exchanger tubes from turbulence
induced erosion

The Dri-Seal Jiffy Plug is our latest patented development and
offers a new and inexpensive way of sealing failed heat
exchanger tubes safely and with the minimum of fuss.
The Dri-Seal Jiffi-Plug has been developed be the safest and
most cost effective form of plugging failed heat exchanger
tubes. Produced from high performance plastics, the plugs can
withstand temperatures up to 150° C and pressures up to 300psi,
and are suitable for a wide range of heat transfer fluids and
gases.
One of the most common and irritating problems for the
maintenance engineer is that of sealing failed heat exchanger
tubes without causing damage to the surrounding tubes or
tubeplate. Common methods of tube sealing include the use of
tapered metallic plugs which are driven into the ends of the
failed tubes. This process is not only unsafe and unreliable,
but the plugs themselves can be extremely expensive due to their
"made-to-order" nature.

The Dri-Seal Jiffi-plug Tube Sealing System solves all of these
problems in one easy step. The use of strong yet flexible
polymer and copolymer materials ensures that even
eroded/corroded tubes can be sealed without causing any damage
or deformation to the tubes or tubeplate ligaments. The lack of
complex mechanics within the sealing mechanism ensures that the
Jiffi-Plug is both cost-effective and simple to fit.
The standard Dri-Seal Jiffi-Plug is produced from high
performance Du Pont Hytrel and Acetal copolymer materials which
have been selected for their temperature range and good chemical
resistance. For information on the chemical resistance
properties of the Dri-Seal Jiffi-Plug, please see our Chemical
Resistance Guide.
The main body of the plug is produced from DuPont Hytrel, a high
performance elastomer chosen for it’s wide chemical resistance
and property retention at elevated temperatures. The fixing pin
is produced from Acetal copolymer, again chosen for it’s
chemical resistance and property retention characteristics at
elevated temperatures. Please see our Material Characteristics
Guide for more information.
The Dri-Seal range of Jiffi-Plugs currently covers most
applications from 3/8" to 1" tube (outside diameter), with more
being added all the time. Should the plug you require not be
included in our plug availability list please contact us via our
Contacts section for more information.
To ensure optimum performance, the plugs are specifically
matched to the tube outside diameter and gauge (wall thickness).
Please be sure of the figures for your application when
enquiring about plugs. |
