Frequently Asked Questions
Q: What is the JT PT2748W-70 o-ring and what does it seal?
A: The JT PT2748W-70 is an o-ring seal for Jet W Series manual pallet jacks. It fits the PT2748W pump assembly and other component interfaces. O-rings prevent hydraulic fluid from leaking at connection points and shaft seals, maintaining system pressure and preventing contamination.
Q: How do I know if this o-ring is worn out or needs replacement?
A: Replace the JT PT2748W-70 o-ring if you notice hydraulic fluid leaking from the pump assembly, shaft seal, or cylinder connection. Also replace it if the o-ring is cracked, hardened, compressed set, or loses its elasticity. Dried out or brittle seals cannot compress properly and will leak under pressure.
Q: What material should o-rings be made from for pallet jack hydraulic systems?
A: O-rings for pallet jack hydraulic systems are typically made from nitrile (NBR) or fluorocarbon (FKM) elastomers, both compatible with standard hydraulic oils. The JT PT2748W-70 is engineered for Jet W Series equipment and hydraulic fluid compatibility. Use only OEM or equivalent seals to avoid incompatibility that could cause swelling or seal failure.
