Standard Pipe
Flange: We stock all
popular sizes and materials for immediate shipping.
Custom
Gaskets: We handle any
size or shape. We fabricate these gaskets the same day, or
within the hour if needed.
Encapsulated: A gasket of
one material is totally enclosed in a continuous layer of
another material (usually Teflon®) with no join. Usually done
with O-Rings and Molded Seals.
Envelope: A gasket of one material is covered by an envelope of another
material (usually Teflon®). We supply slit or milled envelopes
and conventional or square form shields.
Laminated: Two or more materials are
layered together to form a gasket which is often enclosed in an
envelope.
Molded/Extruded/Vulcanized: See O-Rings & or Extruded and
Molded Gaskets
Boiler: We fabricate old-style fiberglass
boiler gaskets for hand-holes and man-ways, as well as
peroxide-cured EPDM Topogee gaskets. We supply any size of
spiral-wound gasket for modern boilers.

 GLASS FIBRE
TAPES, ROPES AND CORDS |
|
|
|
 Glass
fiber is a product that is easily knitted to form tapes,
ropes and cords. Tapes are used as heat proof seals on
boiler or oven doors and usually come plain, or latticed.
Ropes and cords may be similarly used, or used as pipe
insulation. Many widths, and diameters are available. All
come in rolls, usually 30 meters in length.
This product has excellent
thermal resistance, but should not be used as a seal against
pure steam. Because of it's soft pliability it is excellent
for filling gaps where temperatures are relatively high, but
pressures are low.

 Most
boilers have access ports built into them. These are sealed
by oval shaped lids. Gaskets suitable for use with manholes
come in three broad styles. |
-
RUBBER
A specially formulated rubber is used to withstand the
constant temperature and pressure to which these gaskets
are subjected. A rubber gasket should not be used above
180 deg. C.
-
FIBER GLASS
Vulcanized fiberglass may be used instead of rubber and
above 180 deg. C. This type of gasket consists of soft
woven fiberglass bonded with rubber to give it resilience
so that it will seal.
-
Spiralwound
A specially shaped spiral wound may be used. In this case
the spiral is wound in an oval and does not have inner or
outer rings. Used where temperatures limit the use of
rubber and fiberglass. The oval access doors must have
well finished seating surfaces for this style of gasket to
work properly.

Sponge products can be
supplied in either PLAIN or SELF ADHESIVE BACKED form.
Sponge rubber comes in two main formats, CLOSED CELL or OPEN
CELL.
Closed cell sponges have no connecting cavities, making it
ideal for applications where water exclusion and sound and
gas retention are important. It is also much more resistant
to compression and has excellent thermal insulation
characteristics.
Open cell sponges have a
greater compression set and are less shock absorbent.
Sponge is available in many grades, in roll form, cut to any
width, or in a die cut form where it can be converted into
any size and shape. Also available as o-ring cord.
