Matching seal (radial shaft seal)

12 × 37 × 7 mm

Seal weight: ≈ 9 g

Other common widths: 12 × 37 × 10 mm

The seal's inner diameter matches the shaft (12 mm) and its outer diameter matches the housing bore (37 mm); the width depends on the space in the housing. NBR (double lip, TC type) is recommended for general use and FKM (Viton) for high temperatures.
