LIQUID-COOLING CONNECTORS & SEALS
Liquid-cooling connector lubrication
Define whether lubrication is needed and which surfaces contact coolant, then evaluate the fluid, seal material and actual assembly.
Application evaluation: confirm material suitability on the specific connector with its actual coolant and seal materials.
Locations and evaluation conditions
O-rings and assembly contacts
- Contact location
- Identify O-ring insertion and moving seal interfaces on the actual design.
- Process review
- Follow the component specification to review lubrication needs, boundaries and connection force.
Evaluation inputs
- Seal/mating materials and surface condition
- Connection design, motion, temperature and pressure
- Specified material, application method/dose and keep-outs
Coolant contact
- Contact location
- The location and duration of coolant contact with seals and lubricants.
- Process review
- A PFPE or silicone category alone does not establish suitability; evaluate the actual fluid/material combination.
Evaluation inputs
- Coolant, additives, concentration and current material
- Contact duration, thermal cycles and pressure conditions
- Swelling, extraction/contamination and material effects
Connection and leak evaluation
- Contact location
- Connection/disconnection interfaces and the assembled seal path.
- Process review
- Review connection force, post-cycle condition and leakage using the specified conditions and acceptance method.
Evaluation inputs
- Connection cycles, dwell time and mounting orientation
- Leak criteria, cleanliness and contamination limits
- Manufacturer-specified replacement, cleaning and maintenance
