The Wacker Neuson Breather Line is a genuine OEM component designed for the TH627 indirect-fired air heater. Sourced directly from Wacker Neuson, this replacement line matches the original specification for a direct, hassle-free installation. If your existing breather line is cracked, kinked, or deteriorated, swapping it out with part restores proper crankcase ventilation and keeps the heater running as intended.
Key Features
- Genuine OEM Construction: — Manufactured to Wacker Neuson's original material and dimensional spec, ensuring the line maintains correct internal diameter and pressure tolerance for proper vapor flow.
- Direct-Fit Replacement: — Connects to the existing OEM ports on the TH627 without cutting, splicing, or adapting — the line routes and seats exactly as the original did.
- TH627 Compatibility: — Confirmed fitment for the TH627 indirect-fired air heater (418-02 spare parts list), so you can order with confidence.
- Protects Engine Internals: — A functioning breather line prevents excessive crankcase pressure buildup, which can force oil past seals and lead to oil consumption or seal failure over time.
- Fuel System Safety: — Proper crankcase ventilation prevents combustible vapors from accumulating in unintended areas, supporting safe heater operation in enclosed or confined work environments.
The breather line routes crankcase gases away from the engine and back into the intake or vents them safely to atmosphere, depending on the engine design. This prevents pressure from building up inside the crankcase, which would otherwise push past gaskets and seals and introduce oil into areas of the engine where it does not belong. When the breather line cracks, collapses, or becomes blocked, the resulting pressure imbalance accelerates wear on seals and can cause oil leaks or rough engine operation — making timely replacement an important part of routine heater maintenance.
