The Wacker Neuson is a genuine OEM O-Ring 32 X 4.5 70 Sh designed for the BTS 13 and BTS 11 gasoline cut-off saw series. As a direct Wacker Neuson OEM part, it is manufactured to the exact material grade and dimensional specification required for proper sealing in these saws. This O-ring fits the BTS 13 cut-off saw with 1-inch arbor and the BTS 11 cut-off saw with 7/8-inch arbor, making it essential to confirm your model before ordering. Sourcing part number directly ensures you receive the correct durometer and cross-section for a lasting seal.
Key Features
- Correct Durometer and Dimensional Spec — The 70 Shore hardness rating and 32 x 4.5 mm cross-section are matched precisely to the sealing surfaces in the BTS cut-off saw, maintaining compression under operating heat and vibration.
- Genuine OEM Part — Sourced directly from Wacker Neuson, this O-ring meets the same material specification as the original component installed at the factory.
- Drop-In Installation — Seats directly into the original groove without trimming or modification, making replacement straightforward during routine service.
- Confirmed Fitment for BTS 13 and BTS 11 — Verified for the BTS 13 (1-inch arbor) and BTS 11 (7/8-inch arbor) gasoline cut-off saw models.
- Sealing Integrity Protects Internal Components — A correctly seated O-ring prevents fluid or debris ingress into critical areas of the saw; a deteriorated or improperly sized O-ring can lead to leaks, contamination, and premature component wear.
- Fuel System Sealing Compliance — O-rings in fuel-circuit or carburetor applications must be rated for hydrocarbon exposure; using the correct part number ensures the material is compatible with the fuel system on BTS saws.
An O-ring is a circular elastomeric seal that sits in a machined groove between two mating surfaces, preventing fluid, fuel, or air from escaping the joint. In a gasoline cut-off saw like the BTS 13 or BTS 11, O-rings appear in the fuel system, carburetor, and other critical assemblies where a positive seal is required for safe and consistent engine operation. When an O-ring hardens, cracks, or swells out of its specified tolerances, it loses its ability to hold a seal, causing leaks or pressure loss that can affect starting, fuel delivery, and overall engine performance.
