Frequently Asked Questions
Q: What seals are included in the PT2748A-101 complete seal kit?
A: The PT2748A-101 includes factory-spec molded Buna-N and polyurethane seals for both pump and cylinder repair. The kit provides all necessary internal seals required to restore hydraulic pressure integrity in Jet manual pallet jacks. This is a complete restoration kit, not individual seals.
Q: Which Jet pallet jack models does this seal kit fit?
A: The PT2748A-101 fits Jet model PT2748 manual pallet jacks, including variant frames: Jet A, Jet L, Jet J, and Jet A-L-J. Cross-reference part numbers include JTPT2748A-101, PT2748A-101, Jet PT2748A-101, JTPT2748A101, PT2748A101, and Jet PT2748A101. Verify your equipment frame matches one of these variants before ordering.
Q: What is the difference between Buna-N and polyurethane seals in this kit?
A: Buna-N is a synthetic rubber offering good general-purpose chemical resistance and durability in standard hydraulic environments. Polyurethane provides superior abrasion resistance and longer lifespan in high-pressure applications. This kit includes both materials because different pump and cylinder passages require seal materials matched to pressure and fluid exposure specifications.
Q: How long does a complete seal kit typically last before degradation occurs?
A: Molded Buna-N and polyurethane seals in hydraulic systems typically perform for 3 to 5 years under normal pallet jack duty cycles, assuming clean hydraulic fluid and proper maintenance. Seals degrade faster in cold storage environments or with contaminated fluid. Inspect seals annually for surface cracking or hardening, which indicate degradation and imminent failure.
Q: How should this seal kit be stored before use?
A: Store the PT2748A-101 seal kit in a cool, dry location away from direct sunlight and temperature extremes. Maintain storage temperature between 50°F and 85°F to prevent premature hardening of rubber and polyurethane components. Keep seals in original packaging to prevent dust contamination and UV degradation.
