RUBBER FOAM SEAL USAGE AND
SAFETY
!
The rubber foam seal is made of two parts:
black rubber foam and red silicon seal.
Black rubber foam is mostly used to create
initial vacuum. After it compresses, the red
seal holds the longest and strongest seal.
As long as the initial seal is formed to get
suction, the "strong" seal will also be
formed. The rubber foam seal uses
patented technology and is one of the main
components of the tool. It should be
handled with caution as it directly impacts
the overall performance and safety.
a. The seal can withstand an estimated 900
compression cycles, depending on force
and duration of compression, without any
damage.
b. Avoid rubbing the seal over rough surfaces.
Seal material is very prone to parallel wear
(moving parallel to rough surface in ironing
motion). Lift perpendicularly on very rough
surfaces. Rubbing the seal over a smooth
surface such as granite in the presence of
thick abrasives (thick sand) will damage the
seal and may cause unexpected
detachment.
c. Surfaces with very sharp edges should not
be lifted in parallel hold. Edges sharper than
45 degrees may damage the seal and lead
to sudden vacuum loss and sudden
detachment. The motor should always be
on.
d. Always store the seal covered with a hard
cover. The seal can be easily damaged by
sharp corners and edges when in storage.
The seal should not be stored with any
sharp tools or in contact with any hard
objects (e.g. inside a toolbox).
e. Do not dip the seal in water. The rubber
foam seal is slightly water absorbent.
Unless it is fully dipped in water and soaking
wet, slightly soaking the seal with water will
not damage its performance. If it is soaked
in water, it can be squeezed by hand like a
sponge to dry without damage. It is
advisable to use a dry seal to avoid water
getting sucked into air ducts and inside the
body.
!
Do not dip or use the seal in the presence of
any oil-based products. Oil and oil products
(machine oil + lubricants) will permanently
damage the seal and cannot be removed. If
the seal has absorbed any oil, it should be
disposed of safely, the base should be
cleaned, and the seal replaced.
! Do not use or store the seal in the presence
of chemical solvents. Kerosene, acetone,
turpentine, benzene, acids, etc. and even
their fumes in closed spaces or thin layers
on surfaces can melt the seal and damage
its structure and cause failure.
