Frequently Asked Questions
Q: What is the JT PT2748A-022 O-ring used for in pallet jacks?
A: The JT PT2748A-022 is an O-ring seal component for Jet manual pallet jack hydraulic pump assemblies. It creates a seal in the ram piston hydraulic unit, working with the backup ring (JT PT2748A-021) to maintain system pressure and prevent fluid leakage.
Q: Which Jet pallet jack models use the JT PT2748A-022 O-ring?
A: The JT PT2748A-022 O-ring is compatible with Jet Model A, L, and J series manual pallet jacks, including Jet model AJL units. Confirm your equipment model and serial number before ordering.
Q: How is this O-ring positioned in the pump assembly?
A: The JT PT2748A-022 is positioned at the ram piston seal stack, working alongside the JT PT2748A-021 backup ring. These components seal the hydraulic chamber to contain pressure during the lift cycle.
Q: What indicates that this O-ring needs replacement?
A: Replace the O-ring if the pump loses pressure between strokes, leaks hydraulic fluid, or fails to lift the load consistently. Degraded or damaged O-rings cannot maintain a proper seal against the ram piston.
