19508

Frequently Asked Questions

Q: What seal materials are used in the 19508 CR Super Seal Kit?
A: The 19508 CR Super Seal Kit contains NBR and PTFE hydraulic seal components. The backup ring material is virgin PTFE (ASTM D4894/4895), and all seal materials conform to ASTM D2000 M2BG710 specifications for manual pallet jack hydraulic systems.

Q: Which pallet jack models does the 19508 fit?
A: The 19508 CR Super Seal Kit is compatible with standard manual pallet jack hydraulic pump models. Verify your equipment model and pump configuration before ordering. Contact us with your pallet jack specifications to confirm fitment.

Q: What does the ASTM D2000 M2BG710 specification mean?
A: ASTM D2000 M2BG710 specifies the elastomer material grade and performance requirements for the seal. The material composition ensures the NBR seals maintain integrity, elasticity, and fluid compatibility in hydraulic applications at standard operating pressures and temperatures.

Q: Why is virgin PTFE used for the backup ring?
A: Virgin PTFE (polytetrafluoroethylene) is specified for backup rings because it resists extrusion under high hydraulic pressure, maintains dimensional stability, and provides superior chemical resistance. This material extends seal life and prevents failure under the pressure cycles common in manual pallet jack operations.

Q: Is the 19508 used for routine maintenance of standard pallet jacks?
A: Yes, the 19508 CR Super Seal Kit is designed for routine service and maintenance of standard manual pallet jack hydraulic pump systems. It provides OEM-equivalent seal replacement to restore proper hydraulic function when seals wear or leak.
