ORDER TO CHANGE O’RINGS UNDER THE ELECTRONIC HOUSING
The frequency of changing o’rings under an electronic housing should be dependent on well fluid
types, temperature and gauge usage intensity. With high content H2S we recommend changing
these o’rings every 6 months or 1000 hours in well, which ever comes first.
The frequency of changing o’rings under battery housing is up to the tool operator discretion.
They should be replaced at the first evidences of wear.
All Kuster electronic gauges are furnished with Parker Company Viton o’rings, which cover the
majority of well fluids in the field, however the last decision on which type of o’rings to use is up to
the operator of the gauge.
A wrong choice could lead to tool malfunctioning and denial of warranty. Consult with the o’ring
manufacturer, if you are not sure that these o’rings are suitable for your applications. It is mainly
a concern for the well fluids with high content of H2S.
Electronic housing disassembly:
1. Unscrew slotted nut from the top of the LEMO connector with a fork wrench, which
comes with accessories.
2. Push connector just below the keyway cutout in the housing.
3. With the connector being below the keyway, carefully unscrew electronic housing from
the pressure sub.
4. Remove old o’rings.
5. Check thread and o’ring grooves and lubricate them with Kuster lube grease.
