Overview — Breather Tube 5297725F
5297725F is the breather tube used on CUMMINS engines and components to vent the crankcase or gear housing, releasing internal pressure and carrying oil mist away from the sealing points. We can supply this tube as well as related CUMMINS engine components, in stock or available on order — welcome to enquire by part number.
Parts Characteristics
The tube is formed to the original routing and diameter, sized to pass the ventilating flow without restriction while keeping oil mist from being discharged in quantity. The material resists oil and engine heat and keeps its shape along the original route, so the tube does not collapse or kink in service. End connections match the original fittings at the housing and the discharge point, and the bore is smooth to avoid trapping oil. As an OEM-spec breather line, it restores the designed ventilation of the housing and prevents the pressure build-up that forces oil past seals.
Applicable Models & Applications
This breather tube is used across CUMMINS engine families and driven components where the housing must be vented, including crankcase breather circuits, gear housing vents and accessory drive compartments. Typical applications include construction, industrial, generator and marine installations where the breather line routes from the housing to a separator or a safe discharge point. Confirm the tube diameter, length, end connections and the routing against the original tube removed from your engine before ordering.
Maintenance & Replacement
Check the breather tube at each service for cracks, collapsed sections, blocked ends and loose connections. A blocked or pinched breather line allows pressure to build inside the housing, which shows as oil weeping from seals and gaskets. When replacing, fit the tube along the original routing, keeping it clear of hot manifolds and moving parts, and secure both ends with the original clamps or fittings. Verify the discharge end is not blocked by dirt or debris, and confirm the housing vent port is clear before final assembly.
Price Reference (USD)
The reference price for this Breather Tube (5297725F) is approximately USD 10 – 35 per unit depending on brand grade, quantity and shipping destination. This is a planning estimate only — confirm current pricing and availability with our sales team before ordering.
Value & Service
Breather lines are often overlooked until oil leaks start, so we verify 5297725F against the original CUMMINS specification and confirm the diameter and routing before dispatch. We keep the tube in stock and ship worldwide with tracking by DHL, FedEx or UPS, and our team can advise on the correct breather separator if your application is discharging excessive oil mist. Orders can be consolidated with other engine service parts into one tracked shipment.
