HY 213757

Frequently Asked Questions

Q: What seals and components are included in the HY 213757 hydraulic seal kit?
A: The HY 213757 kit includes NBR elastomer piston seals, rod seals, O-rings, and dust wipers. These seals are designed to work together as a complete system for tilt cylinders or hydraulic motors in Hyster electric lift trucks. The NBR material provides excellent compatibility with petroleum-based hydraulic oils.

Q: What is the maximum hydraulic pressure this seal kit supports?
A: The HY 213757 kit is rated for hydraulic systems up to 3000 PSI. Operating pressures above this specification may cause seal failure and system leaks. Verify your equipment hydraulic system pressure rating matches this specification before ordering.

Q: What type of hydraulic oil is compatible with this seal kit?
A: The HY 213757 kit is designed for use with petroleum-based hydraulic oils. NBR elastomer is compatible with standard mineral hydraulic fluids used in most Hyster material handling equipment. Do not use synthetic or water-based hydraulic fluids unless your equipment documentation specifically approves them, as they may degrade the NBR seals.

Q: What does the 70 Shore A hardness rating mean for these seals?
A: The 70 Shore A nominal hardness indicates the elasticity and compression set resistance of the NBR rubber. This hardness level provides a balance between flexibility for creating effective seals and firmness for resisting permanent deformation under high pressure and temperature. It is standard for hydraulic cylinder and motor applications.

Q: Which Hyster equipment models use the HY 213757 seal kit?
A: The HY 213757 is a dedicated kit for Hyster electric lift trucks and pallet jacks with tilt cylinders or hydraulic motors. Cross-reference your equipment model and cylinder or motor specifications against the OEM parts diagram to confirm this kit is compatible with your specific application.

Q: What is the expected lifespan of the HY 213757 seals?
A: Seal lifespan depends on hydraulic system pressure cycles, oil temperature, and contamination levels. Quality hydraulic fluid maintenance and regular filter changes extend seal life. Signs of seal wear include hydraulic leaks from the cylinder rod or case, sluggish or erratic tilt operation, and pressure loss. Replace the kit if leaks persist after cleaning and fluid level checks.
