87K Swivel Maintenance Kit

Complete rebuild set for Flow 87k cutting head swivels. Refreshes the primary PTFE hoop seal, thrust bearings, O-rings and hardware so the head rotates smoothly under full line pressure without side leak. Use at scheduled service or at the first sign of weepage, rough rotation, or cone fretting—fresh internals restore factory clearances and extend cone, gland and collar life.

Kit includes:

• 2x 87k Blue Swivel Seal (013633-1)
• 2x High Resilience O-rings (B-8075-007)
• 2x 87k Seal Hoop (013634-1)
• 2x Toughmet Backup Rings (014373-1)
• 2x O-rings (A-0275-006)
• 2x 87k Swivel Shaft (048127-1)
• 4x 0.827" OD Bearing (A-18853-0315)
• 2x 21mm OD Bearing (200635-0315-827)
• 2x 1/4" 87k Anti-vibration Collar (SB-0230)
  
• 2x 1/4" 87k Anti-vibration Gland (044347-1)
• 2x 1/4" 87k Anti-vibration Collet (044358-1)

Service tip: after rebuilding, install fresh cones and torque new glands/collars to spec. Verify smooth rotation by hand at zero pressure, then run a brief low pressure test to confirm a dry swivel before returning to full 87k duty.
