PTB profile data

Material codes
Sealing ring: U-1003
X-ring: A-8501
Materials
PressureUp to 400 bar (5 800 psi)
SpeedUp to 1 m/s (3.2 ft/s)
Temperature
range

Extreme low temperature range: may be intermittently exposed (e.g. cold start-up) without seal damage, but seal performance may be compromised while in this range
Temperatures below the recommended operating range: seal performance depends on system design (precision guiding arrangement recommended)
Recommended operating temperature range for this profile and material
Temperatures above the recommended operating range: acceptable only with reduced pressure, speed, e-gap and/or with the use of a full-face anti-extrusion ring
Extreme high temperature range: only occasional short-term exposure (e.g. cylinder in curing oven of a powder coating process)
Dimension
standards
Some metric sizes fit seal housings in accordance with ISO 5597:2010.
