Frequently Asked Questions
Q: What is the PU B-1-27 seal and what equipment does it fit?
A: The PU B-1-27 is a high-resilience polyurethane hydraulic piston seal designed for the lift ram cylinder of Pallet Mule manual pallet jacks. This OEM seal maintains fluid isolation under standard system pressures in manual lift applications.
Q: What are the cross-reference part numbers for PU B-1-27?
A: The PU B-1-27 is cross-referenced as PUB-1-27, PTB-1-27, and PT B-1-27. It replaces the Wesley International drawing and service notation B1-27 10M. Alternate model designations include PU B127 and PU B 1 27.
Q: What material is this seal made from and why does it matter?
A: The PU B-1-27 is engineered from high-resilience polyurethane, a material selected for its durability under hydraulic pressure cycling in manual pallet jacks. Polyurethane provides consistent sealing performance and resistance to standard hydraulic fluids used in material handling equipment.
Q: How do I know if my pallet jack needs this seal?
A: If you operate a Pallet Mule manual pallet jack and experience hydraulic fluid leakage from the lift ram cylinder or notice reduced lifting pressure, the PU B-1-27 seal may be worn or damaged. Verify your equipment matches Pallet Mule models specified for B1-27 10M seal applications.
Q: What happens if this seal fails?
A: A failed PU B-1-27 seal will not maintain hydraulic fluid isolation, resulting in fluid leakage from the lift ram cylinder, loss of lifting pressure, and inability to raise loads. This is a critical hydraulic component and should be replaced immediately when wear or damage is detected.
