Frequently Asked Questions
Q: What is the RA 500-405-49 O ring used for?
A: The RA 500-405-49 is a Raymond OEM O ring designed for dynamic and static sealing in electric lift truck hydraulic systems. It seals hydraulic fluid passages and prevents leakage in cylinders, pumps, and valve assemblies.
Q: What material is the RA 500-405-49 O ring made from?
A: This O ring is manufactured from Buna-N (nitrile rubber) or equivalent elastomer. Buna-N is engineered for resistance to hydraulic oils and mild chemicals commonly used in lift truck systems.
Q: Which Raymond lift truck models use the RA 500-405-49?
A: The RA 500-405-49 is compatible with select Raymond electric lift trucks requiring O ring seals in hydraulic assemblies. Verify your equipment hydraulic system specifications to confirm compatibility before ordering.
Q: How long does a Buna-N O ring last in hydraulic service?
A: Nitrile rubber O rings typically provide 3 to 5 years of service in normal hydraulic duty. Service life depends on operating temperature, fluid type, pressure cycles, and contamination levels. Cooler operating conditions extend lifespan.
Q: What fluid temperatures can this O ring withstand?
A: Buna-N O rings are rated for continuous service from minus 40 degrees Fahrenheit to 250 degrees Fahrenheit. Hydraulic oil in lift trucks typically operates between 110 and 140 degrees Fahrenheit, well within this range.
