Die-cut
Gaskets
Application Information:
Die-cut gaskets are made by stamping out a piece of rubber and
then attaching one of our types of spiral to it. Die-cut gaskets
are economical when sealing the cover of a box at a high volume.
They also allow unusual shapes to be sealed more easily. Spiral
can be placed inside or outside so the rubber can be correctly
oriented to achieve environmental sealing.
Available Options:
Die-cut gaskets can be made using any type
of spiral and many types of rubber including those shown below.
Other types may be available. Please contact
us for information.
- EPDM
- Neoprene Sponge (adhesive backing mandatory)
- Silicone Sponge (adhesive backing available)
- Solid Silicone (adhesive backing available)
- Solid Fluorosilicone
Ordering Information:
Please contact us
with your requirements or fax a sketch or drawing (please include
tolerances). For solid rubber, we recommend that the rubber thickness
be approximately 75% of the diameter of the spiral. For sponge
rubber, we recommend the rubber thickness be approximately the
same as the diameter of the spiral.
Framed Gaskets
Application Information:
Framed gaskets are made by forming Spira-Strip, Quick-Strip or
Basic Multi-Seal into a rectangle to your specifications. The
corners are miter cut and glued. The spiral can be attached
before cutting the corners (90 degree corners) or after (radius
on the corners).
Available Options:
Framed gaskets can be made using the following
types of Spira gaskets:
Ordering Information:
Please contact us
with your requirements or fax a sketch or drawing (please include
tolerances). Framed gaskets are ordered by the piece.
Custom O-Rings
Application Information:
O-rings are made using a standard or custom size groove mounted Spira gaskets. O-rings can be used either in circular or rectangular groove applications. We assemble the o-rings either by winding one end of the spiral into the other and soldering (Spira-Shield and Quick-Shield) or using adhesive (Endur-o-Shield, Flexi-Shield and “D” Multi-Seal).
When installing a “D” Multi-Seal o-ring into a rectangular groove, put the corners in first, then press the gasket into the straight sections of the groove. We recommend a corner radius of 1 1/2 times the diameter of the spiral or width of the “D” Multi-Seal gasket.
Available Options:
Custom o-rings can be made from several types of Spira gaskets:
Ordering Information:
Please contact us or fax a sketch or drawing which includes the spiral part number, the inside diameter (ID) of the o-ring and the tolerance on the ID.
