Frequently Asked Questions
Q: What is the purpose of the JT PT2748A-018 back-up ring?
A: The JT PT2748A-018 is a back-up ring used in Jet manual pallet jack hydraulic seal assemblies. Back-up rings provide support to primary seals under high-pressure conditions and prevent extrusion into seal gaps.
Q: Which Jet pallet jack models is the JT PT2748A-018 compatible with?
A: The JT PT2748A-018 fits Jet A, L, and J series manual pallet jacks, including model AJL. It is a component in the hydraulic pump assembly seal stack.
Q: Where is the JT PT2748A-018 positioned in the seal assembly?
A: The back-up ring is positioned behind the primary O-ring seal in the hydraulic cylinder bore. It works in conjunction with the O-ring to maintain pressure containment and prevent seal failure.
Q: Should the JT PT2748A-018 be replaced with the primary seal?
A: When replacing primary hydraulic seals in a Jet manual pallet jack, it is standard practice to replace the back-up ring at the same time to ensure optimal seal assembly performance and prevent future leakage.
