Applicable Scenarios

It is used for oil diversion and confluence of hydraulic pipelines of 5-ton wheel loader, matched with hydraulic pumps, valve blocks and oil cylinders, suitable for earthwork, quarry, sand yard and port loading and unloading.

• Produced in accordance with OEM standards, thread and size fully match original parts for direct replacement.
• Forged integrated structure, high density, good pressure resistance, not easy to crack under cyclic pressure impact.
• Smooth inner runner, low flow resistance, reduce pressure loss and hydraulic heat generation.
• Accurate thread processing, good fit with pipe fittings, stable sealing after assembly.
• Compact structure, occupy little installation space, neat pipeline arrangement.
• Strong anti-vibration performance, not easy to loose thread under long-term vibration.
• Strict pressure test before delivery, stable batch quality, easy spare parts management.

FAQ 

Q: Can I change the direction of the oil port by processing the tee fitting myself?
A: It is forbidden. Random machining will damage the structural strength and cause crack and oil leakage under pressure.

Q: What are the common causes of oil leakage of the tee fitting?
A: Damaged sealing ring, thread bruising, excessive or insufficient tightening torque, scratch on the sealing cone surface will lead to leakage.

Q: What should be checked before installation?
A: Check whether the fitting body has cracks, sand holes and thread damage, clean sundries inside the oil port.

Q: What should I pay attention to when screwing the thread?
A: Keep the thread clean, apply a small amount of hydraulic oil for lubrication, and control the tightening torque.

Q: Can the old sealing ring be reused after disassembly?
A: It is not recommended. The sealing ring will deform and age after disassembly, which affects the sealing reliability.

Q: How to maintain the tee fitting in daily use?
A: Regularly check each oil port for oil seepage, avoid heavy impact and collision on the fitting body.

Q: What is the difference between forged tee and cast tee?
A: Forged tee has denser material, higher pressure resistance, suitable for high-pressure hydraulic circuit; cast tee is mostly used for low-pressure circuit.
