Frequently Asked Questions
Q: What is the maximum pressure rating for the CR 111149 seal kit?
A: The CR 111149 brake manifold seal kit is rated for hydraulic systems to 3000 PSI nominal. This pressure range covers standard Crown electric lift truck brake systems. Do not use in systems exceeding rated pressure.
Q: What material are the CR 111149 seals made from?
A: The CR 111149 seals are manufactured from premium NBR (nitrile butadiene rubber) elastomer, manufactured in compliance with ASTM D2000 standards. NBR provides excellent resistance to hydraulic fluid and temperature cycling.
Q: Is the CR 111149 equivalent to the SK-48220908SR?
A: Yes, the CR 111149 is equivalent to SK-48220908SR. Both seal kits are designed for Crown electric lift truck brake manifold applications. Verify manifold port dimensions and seal cavity configuration before ordering.
Q: How often should the brake manifold seals be replaced?
A: Brake manifold seal replacement is typically performed during routine brake system service when seals show signs of leakage, fluid contamination, or pressure loss. NBR seals are durable; replacement interval depends on fluid condition and system temperature cycling.
Q: What compatibility does this seal kit have with non-Crown equipment?
A: The CR 111149 is engineered for Crown brake manifold geometry and cavity specifications. While NBR seals are industry standard, manifold port sizes and configurations vary significantly across manufacturers. Verify manifold specifications against kit dimensions before use.
