PM L10

Frequently Asked Questions

Q: What is the PM L10 and what does it seal?
A: The PM L10 is a polyurethane U-cup hydraulic seal used in Palletmaster manual pallet jack hydraulic units for sealing the main cylinder. It provides bidirectional sealing capability and is designed for direct fit in factory seal grooves.

Q: What material is the PM L10 made from and why?
A: The PM L10 is manufactured from polyurethane elastomer selected for high pressure and abrasion resistance in hydraulic applications. Polyurethane provides superior seal durability and maintains performance across hydraulic fluid exposure and pressure cycling in manual pallet jack systems.

Q: What equipment is the PM L10 compatible with?
A: The PM L10 is specifically compatible with Palletmaster model HSW manual pallet jacks. This U-cup seal is engineered to fit Palletmaster hydraulic cylinders and is not interchangeable with other pallet jack brands or models.

Q: What are the pressure and performance specifications for the PM L10?
A: The PM L10 is engineered for high-pressure hydraulic applications in manual pallet jack systems. The polyurethane construction provides abrasion resistance and bidirectional sealing capability, meaning it seals effectively during both upstroke and downstroke cylinder movement.

Q: Can the PM L10 be used as a replacement for other U-cup seals?
A: No. The PM L10 is engineered for direct fit in Palletmaster model HSW hydraulic cylinders. Other pallet jack brands and models use different U-cup seal dimensions and groove specifications. Using an incorrect seal will result in leakage or seal failure.
