O-ring, 43 x 1.5 mm – Viton, Part# 20009515 – vacstellar

This O-ring is made from Viton, a high-performance synthetic rubber. Viton is chosen for a reason. It resists oils, fuels, and many chemicals very well. It also handles higher temperatures better than standard rubbers. This toughness means the seal lasts longer. You get reliable performance even in demanding conditions. 

O-rings are wear parts. Over time, they can harden, crack, or flatten. This leads to vacuum loss and can strain your pump. Replacing a worn O-ring with this part is simple, cost-effective maintenance. It restores your pump’s seal and protects your investment.

Keep your Leybold D1.6B pump in top shape. This Viton O-ring delivers the precise fit and durable performance you need.
