PTB rod seals
Hydraulic seals - Rod and buffer seals - PTB/SKF
PTB seals are energized U-cup rod seals and (fig. 1) are made of LUBRITHANE (TPU). They are suitable for pressures up to 400 bar (5 800 psi) in medium duty appliC-A-Tions and are available in metric and inch sizes.

| Material codes | Sealing ring: U-1003 X-ring: A-8501 → see Engineering information below |
| Pressure | Up to 400 bar (5 800 psi) |
| Speed | Up 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 |
