Piston Seal

Frequently Asked Questions

Q: What is a piston seal and what does the PR A-49932-1 do?
A: The PR A-49932-1 is a piston seal that creates a tight fit between a piston and cylinder bore, preventing hydraulic fluid leakage and maintaining pressure in hydraulic systems used on electric lift trucks.

Q: Which electric lift truck hydraulic systems use the PR A-49932-1 piston seal?
A: This seal is used in hydraulic cylinders across multiple OEM brands including Crown, Toyota, Raymond, and Jungheinrich. Verify the cylinder type and bore diameter against your equipment specifications.

Q: What happens if the PR A-49932-1 piston seal fails or leaks?
A: A failed piston seal causes hydraulic fluid loss, reduced system pressure, and loss of lift or lowering function. Replace the seal immediately to restore system performance and prevent further damage.

Q: What material is the PR A-49932-1 piston seal made from?
A: Most piston seals are made from nitrile rubber, polyurethane, or PTFE compounds. Check the material specifications for the PR A-49932-1 to ensure compatibility with your hydraulic fluid type.

Q: How often should the PR A-49932-1 piston seal be replaced?
A: Seal lifespan depends on operating temperature, pressure cycles, and fluid cleanliness. Replace when leakage is visible or system pressure drops despite proper fluid level.
