🔎 Buna or Viton seals? F1 seal kits are available in both Buna-N (Nitrile) for standard petroleum oil and Viton (Fluorocarbon) for high temperatures or aggressive fluids. Tell us your fluid type and operating temperature and we'll spec the correct seal kit for your rebuild.
How to Identify Your F1
Find the model code on the nameplate — it starts with F1 followed by the size (25/41/51/61/81/101) and rotation (R/L). To get the right parts, send us:
  1. The complete model code from the nameplate (or a clear photo).
  2. Your fluid type and operating temperature (to confirm Buna-N vs Viton seals).
  3. What you need — seal kit, rotating group, or complete pump.
