A small family, organised by material
The oil seal family is the catalogue's smallest at 29 listings, and it is organised the way seal orders actually arrive: by material first, then by size. The company publishes the range in six materials — NBR, Silicone, FKM, EPDM, ACM and PTFE — and the material is not a detail: it decides what the seal can survive.
An oil seal keeps lubricant in and contamination out at a rotating shaft — crankshaft, camshaft, wheel hub and gearbox positions across the vehicle. Seals are consumable companions to the bearing families: a hub or bearing job that disturbs a seal usually closes with a new one.
The six materials and where each belongs
NBR is the general-purpose oil seal material. FKM is ordered for higher temperatures and aggressive oils. Silicone suits wide temperature swings at lower mechanical stress; EPDM is the choice around water and steam rather than oil; ACM serves transmission fluids; PTFE covers the demanding, low-friction positions. The table summarises the published range.
| Material | Typical ordering reason |
|---|---|
| NBR | General-purpose oil sealing |
| Silicone | Wide temperature range, light duty |
| FKM | High temperature, aggressive oils |
| EPDM | Water and steam environments |
| ACM | Transmission fluid service |
| PTFE | Low-friction, demanding positions |
Ordering seals without a number
Seals are ordered by the three dimensions — bore, outside diameter and width — plus the material. Where an inquiry names a position, such as a crankshaft or camshaft seal, it is matched against the published range by size; the catalogue lists materials rather than position-specific product lines, so the dimensions on the old seal are the reliable reference.
Seals on a bearing order
Because seals are small and cheap next to a bearing, they are usually added to a bearing or kit order rather than shipped alone. Say in the inquiry which positions the seals are for and they will be quoted on the same list.
