Component Specifications

Definition
The overflow tube connection is a critical fluid management component in industrial coolant systems, designed to create a sealed interface between the reservoir's overflow outlet and external drainage piping. It ensures controlled discharge of excess coolant when reservoir levels exceed operational capacity, maintaining system pressure balance and preventing spillage. Engineered with specific dimensional tolerances and material compatibility for corrosive coolant environments.
Working Principle
Operates on gravity-driven fluid dynamics and pressure equalization. When coolant level rises above the designated maximum fill line, hydrostatic pressure forces fluid through the connection into the overflow tube. The connection maintains a continuous sealed pathway while allowing unimpeded flow, with design features preventing backflow and ensuring proper drainage orientation.
Materials
Stainless steel 316L (corrosion-resistant), PTFE-lined brass, or engineered polymers (PP, PVDF) depending on coolant chemical composition. Temperature rating: -40°C to 120°C. Pressure rating: 0-2 bar.

  • Size Range 1/2" to 2" diameter
  • Flow Capacity 15-60 L/min
  • Leak Pressure ≥1.5x operating pressure
  • Surface Finish Ra ≤ 3.2 μm
  • Connection Type Threaded (NPT/BSP) or quick-connect
  • Chemical Compatibility Resistant to glycol, oil-based, and synthetic coolants
Standards
ISO 1179, DIN 3852, ISO 6149

Frequently Asked Questions

What maintenance does an overflow tube connection require?

Regular inspection for cracks or corrosion, cleaning of internal passages every 6 months, and torque verification of threaded connections annually.

Can overflow connections be used with different coolant types?

Material selection is critical - stainless steel for most coolants, PTFE-lined for aggressive chemicals, and specific polymers for synthetic fluids.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
