First Stage Seat Tool Set

RBTOOL25/SK - First Stage O-Ring & Seat Applicator Tools

For use with post-Feb 2025 AP97N AP First Stage service kits (for FS101, FS101A & FS101A/G first stages)

[Note: All pre-Feb 2025 First Stages (FS101, FS101A & FS101A/G) should now be serviced with the new AP97N kits]

Kit Includes:

RBTOOL23 - FS101 O-Ring Applicator Tool for fitting of the O-ring to the HPV Seat

RBTOOL24 - HPV Seat Applicator Tool for removing and re-fitting the HPV seat in the main body

For use with post-Feb 2025 AP First Stage service kits, that is, with the brass FS20A HPV Seat, rather than the molded (white or translucent) pre-Feb 2025 FS20 HPV Seat.

WARNING - Both tools should be made oxygen clean before use. Take great care not to introduce potentially combustable debris to the interior of the first stage.
