Frequently Asked Questions
Q: What does the O-Ring JT PTX2748-071 seal in a Jet pallet jack?
A: The JT PTX2748-071 is a dynamic or static seal O-ring that prevents hydraulic fluid leakage at connection points in the hydraulic unit assembly. It sits in grooves on valve bases or pump housings to maintain system pressure.
Q: Which Jet pallet jack models use O-Ring JT PTX2748-071?
A: The JT PTX2748-071 O-ring is compatible with Jet PTX and JTX series manual pallet jacks. Cross-reference your equipment documentation to confirm the correct seal size before purchasing.
Q: What material is the O-ring made from and why does it matter?
A: The O-ring is typically made from EPDM rubber or nitrile (NBR) that resists hydraulic oil and maintains elasticity under pressure. EPDM is more temperature-resistant; NBR offers better oil compatibility. The material choice affects longevity in cold storage or high-heat environments.
Q: When should I replace the JT PTX2748-071 O-ring?
A: Replace the O-ring if you see active oil seepage from the hydraulic unit, if the jack loses pressure within minutes when fully loaded, or as part of a planned seal kit replacement every 3 to 5 years depending on equipment use frequency.
