The Supertech 21mm piston circlip with 1.50mm wire is a retaining clip sized to secure a 21mm piston pin inside the piston. The 1.50mm wire specification corresponds to the clip cross-section used for groove fitment. Use these circlips during piston and pin installation to lock the wrist pin in place and prevent unwanted axial movement.
