Piston seals are installed on the piston to separate fluid chambers, while rod seals are on the cylinder rod to prevent external leakage. Both are dynamic seals but serve different locations in the system.
Replacement intervals depend on operating conditions: typically 1-5 years or 10,000-50,000 cycles. Monitor for increased leakage, pressure drop, or visible wear as replacement indicators.
Yes, symmetrical designs like U-cups or double-acting seals handle pressure from both directions. Single-acting seals only work with pressure from one specific side.
