description

This original hydraulic swivel joint is precision‑machined from high‑strength alloy steel, fitted with wear‑resistant rotary pairs and multi‑stage combined seals for reliable high‑pressure resistance against repeated hydraulic shocks. Standard threads on both ends connect directly to steel pipes or high‑pressure hoses. When hoppers lift, chains tension and feeding motors run, connected lines swing with moving parts. The swivel releases torsional stress and prevents fatigue fracture of hoses. External leakage, stiff rotation or failed internal seals will drop system pressure and reduce power, disrupting material feeding. Replace the whole swivel during hydraulic overhaul if leakage or binding occurs.

product parameters

- Function: Rotary hydraulic connection, vibration absorption, stress relief and oil circuit sealing

Applicable Scenarios

Hydraulic line connection for paver hopper cylinders; oil line transition for feeding drive motors; positions where hoses swing and twist; replacement for leaking or seized old swivels; overhaul and maintenance of feeding hydraulics; pre‑assembly for new hydraulic piping.

advantage

- Precision original machining with standard threads and sealing surfaces for easy fitting
- Multi‑seal construction withstands high pressure and resists leakage over long service
- Smooth rotation releases hose torsion and extends service life of high‑pressure hoses
- Robust housing resists grit erosion for harsh asphalt site conditions
- Modular assembly for quick replacement once failure appears

FAQ

Q: Can only seals be replaced for minor leakage?
A: If the rotary surface is worn, leakage will recur even with new seals. Seal replacement works only for aged seals with intact running surface. Full replacement is recommended for heavy wear.

Q: What are the key points for swivel installation?
A: Do not grip the rotating core with a wrench. Leave slack in piping to avoid tension restricting free rotation.

Q: Does stiff rotation mean the swivel is broken?
A: Slight preload on new units is normal. Progressive stiffening together with leakage indicates internal wear and requires replacement.

Q: Can swivels of the same part number be swapped between hydraulic positions?
A: Interchange is permitted for identical part number. Run the system after installation and check for leakage and hose interference.
