O-ring Installation and Removal
CAutIoN:
Replace the o-ring every time the
housing is opened.
1. Verify that the o-ring is installed in the housing.
If not, properly seat an o-ring into the housing
bowl, as described below.
2. Prewet the housing o-ring with a fluid compatible
with your process chemical (such as DI water,
IPA, etc.) to aid in installation and ensure a
proper seal.
3. For best results when using E-FKM o-rings,
heat the o-ring to 60°C prior to installation.
Heat the o-ring by immersing in hot water for
2 minutes, or by placing the o-ring 25 mm (1”)
below a 250-watt heat lamp for 1 minute.
Install the o-ring while it is still warm.
4. For all housings, handle the o-ring with care.
Insert the o-ring into the groove and push the
o-ring securely and evenly in place.
DO NOT
roll or twist the o-ring.
5. To remove the old o-ring, slide the hook end of
the housing wrench tool under the o-ring, then
slide the tool around the bowl.
CAutIoN:
use caution when removing the
o-ring. Contacting the o-ring seal areas
with the removal tool can damage the
sealing surface.
