The Supertech 20mm piston circlip with 1.50mm wire is a precision piston pin retaining clip sized for 20mm pin applications. Its wire diameter is specified to match pin and piston groove dimensions, securing the wrist pin and preventing axial movement. Install these circlips during piston assembly to keep the pin correctly located under normal engine operation.
