Frequently Asked Questions
Q: What materials are used in the 19508 seal kit?
A: The 19508 contains NBR and PTFE hydraulic seal components. The backup ring is made of virgin PTFE, which meets ASTM D4894/4895 specifications.
Q: What does the ASTM D2000 M2BG710 specification mean?
A: ASTM D2000 M2BG710 specifies the elastomer material grade and performance requirements for the seal. It ensures the NBR seals maintain integrity, elasticity, and fluid compatibility in hydraulic applications.
Q: Why is virgin PTFE used for the backup ring?
A: Virgin PTFE 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 pressure cycles.
Q: Is the 19508 used for routine maintenance of manual pallet jacks?
A: Yes, the 19508 is designed for routine service and maintenance of manual pallet jack hydraulic pump systems. It provides seal replacement to restore proper hydraulic function when seals wear or leak.
