5.1.6
Replacement of O-Rings
Pressure Systems’ calibration valves include static and dynamic O-ring seals. When used
properly, the rated durability of the dynamic O-rings is in excess of 1,000,000 shifts of the
calibration valve.
The procedures described below should be used for replacement of all the O-rings in the Model
9116 Intelligent Pressure Scanner. Use the tools and follow the general warnings already
described at the start of Section 5.1.
The material needed for the O-ring replacement can be acquired through the proper
maintenance kit available from Pressure Systems. Specifically needed for these procedures are
calibration manifold and piston O-rings, Teflon cup seals, a fast evaporating cleaning fluid ( i.e.
acetone, alcohol, Freon
®
, etc.), 50 psi dry air supply, and Krytox
®
fluorinated grease (read
product warnings and recommendations thoroughly). Service of O-ring seals requires a
clean working environment. Introduction of contaminants to the O-ring or internal calibration
manifold surfaces can result in internal pneumatic leaks. Inspection for contaminates generally
requires some type of magnification device, such as a microscope.
