Precautions on Handling the O-ring
CAUTION
Are there any scratches or cracks in the O-ring?
Be careful about dust, sand, and hair
=
SEA&SEA products use blue O-rings. These O-rings are impregnated with
silicone oil through a special process. The lubricating effect of the O-ring lasts
as long as the silicone oil is gradually seeping out from within.
=
For the maintenance of these blue O-rings, make sure to use genuine SEA&SEA
silicone grease (O-ring grease for use with the blue O-rings that comes in tubes
with blue lettering and blue caps). If you use silicone grease from other companies
or SEA&SEA’s own silicone grease that comes in tubes with black lettering and
black caps, the grease you apply will be sucked into the blue O-rings due to
their special characteristics, which will result in insufficient grease. If this happens
even once, the O-ring will not revert to its normal state and must be replaced.
=
If the grease is insufficient, the O-ring will not slide, and it will become harder
to open and close the waterproof parts. Because of this, it could become
impossible to open or close the housing or it could cause flooding, so please
refrain from using the housing with insufficient grease.
Check the O-ring to make sure there are no
scratches or cracks. If there are, replace the
O-ring with a new one immediately. When
handling the O-ring, do not use pointed
metal objects, which could damage the
O-ring. Use of the included O-ring remover
is recommended.
Check the O-ring to make sure that there is no dust, sand, or hair on the O-ring,
in the O-ring’s grooves, or on the O-ring’s contact surfaces. If any of these things
are attached, remove them completely. If used as is, these things could cause
flooding.
This product is kept watertight by the O-ring. To keep the O-ring functioning
properly, please observe the following. Improper handling of the O-ring could
cause flooding.
