Overview – O-SHAPE CONNECTOR 3080401X
The Cummins O-SHAPE CONNECTOR 3080401X is specified for Cummins hydraulic and fluid connections as the O-shape seal connector and is supplied to the original dimensional and material standard.
Parts Characteristics
An O-shape seal connector (O-ring) that seals a fluid joint against pressure and contamination. It is the lowest-cost part in the circuit, yet when it weeps the whole hydraulic line loses pressure, so a correct, compound-matched ring keeps the joint sealed and the circuit charged.
Applicable Models & Applications
Used at Cummins hydraulic connection points of this O-shape. Match the cross-section, inside diameter and material compound against your old seal or the parts book – O-rings that look identical differ in durometer and fluid resistance.
Maintenance & Replacement
Replace every O-shape connector whenever the joint is opened, never reuse a stretched one. A ring that has taken a set leaks the first time pressure cycles, and a weep at a fitting becomes a pressure loss and then a failure.
Match the compound to the fluid. A nitrile ring in a synthetic-hydraulic or high-temperature circuit hardens and cracks, while the right compound stays supple for the service interval.
Lubricate the ring lightly on fit and keep it clear of the thread. A seal rolled into the thread cuts itself the moment torque is applied, which is the most common cause of a joint that leaks from new.
Keep a range of common O-shape connectors for your hydraulic connections on the bench. They cost almost nothing, they fail quietly with age, and they are exactly the part missing when a line needs sealing today.
Price Reference (USD)
Budget roughly USD 1 to USD 12 for a O-SHAPE CONNECTOR 3080401X; volume orders and stock status can move this range either way.
Value & Service
We supply brand-new O-shape seal connectors with the cross-section and compound confirmed against your Cummins hydraulic application, so the joint stays sealed.
