JT PT2036-2-35

Frequently Asked Questions

Q: What does the JT PT2036-2-35 U-Cup seal do?
A: The JT PT2036-2-35 is a dynamic hydraulic seal engineered for the lift ram cylinder in Jet PTW Series manual pallet jacks. The U-Cup design prevents pressurized hydraulic fluid from leaking past the piston rod, maintaining lifting performance.

Q: Which Jet pallet jack models use the JT PT2036-2-35 U-Cup?
A: The JT PT2036-2-35 fits Jet PTW Series manual pallet jacks. It is specified for the hydraulic ram assembly and is referenced as item 52 in the OEM parts catalog.

Q: Why do U-Cup seals fail in hydraulic cylinders?
A: U-Cups wear from repeated rod travel, contaminated hydraulic fluid, metal shavings, and pressure cycling. Hardened seals, flattened profiles, or extrusion past retaining rings result in internal leakage. Weak or slow lift response indicates U-Cup degradation.

Q: What material is the JT PT2036-2-35 U-Cup made from?
A: The JT PT2036-2-35 is manufactured from OEM-specification elastomer formulated for dynamic sealing in hydraulic cylinders. The material resists mineral oil degradation and maintains elasticity under pressure cycling and temperature variation.

Q: How often should a hydraulic ram U-Cup be replaced?
A: U-Cup seals typically last 3 to 5 years in normal warehouse service. Heavy-duty applications, contaminated oil, or cold storage use accelerates degradation. Fluid analysis and lift speed tests can indicate replacement timing.

Q: Does the JT PT2036-2-35 fit all Jet PTW hydraulic ram cylinders?
A: The JT PT2036-2-35 is designed for Jet PTW Series equipment. Verify your model year and hydraulic cylinder part number against the OEM catalog before ordering, as some service bulletins may specify alternate seal part numbers.
