TEADIT supplies PTFE, compressed-fiber and spiral-wound gaskets for data-center liquid cooling and backup power. Applications include coolant distribution units (CDUs), facility water systems, heat exchangers, pumps, valves and pipe flanges. Material selection depends on the coolant, flange design, temperature, pressure and available bolt load.
Liquid-cooled data centers rely on many flanged joints. Low-rigidity flanges cannot take heavy bolt load, so gaskets need low seating stress and creep resistance.

Reliable IT operations also depend on the cooling, power and fluid-handling systems behind the servers. These practical takeaways from our eBook explain why sealing deserves attention throughout the life of a facility.
Power Usage Effectiveness (PUE) compares total facility energy with the energy used by IT equipment. Cooling, pumping and fluid-system integrity contribute to the non-IT energy load. The eBook connects leaks and pressure instability with additional pump demand and less efficient cooling. Better sealing is one part of a wider efficiency strategy—not a standalone promise of a lower PUE.
Flanges, valve interfaces, pump connections, heat exchangers and expansion joints are potential leak locations. A small leak may develop below monitoring thresholds before it becomes an obvious failure. The eBook describes how persistent leakage can affect cooling efficiency, pressure stability, maintenance frequency and equipment wear.
Thermal cycling, pressure fluctuations, vibration and chemical exposure continue after commissioning. Gaskets can relax, bolt loads can change and materials can degrade in service. Selection therefore needs to consider long-term operating conditions, coolant additives, creep resistance and sealability at the available seating stress.
A specified gasket can still underperform when installation or handling varies. The eBook highlights improper compression, misalignment and uneven load distribution as risks. Consistent material selection, joint-specific torque requirements, installation procedures and team training help reduce the gap between the designed joint and the installed joint.
Our team helps match gasket materials to the flange, coolant and operating conditions, and supports the joint through installation.

Low-rigidity HDPE flanges require a gasket that seals at the available bolt load without excessive flange distortion. TEADIT identifies 24SH expanded PTFE for plastic and other low bolt-load applications. Final selection must account for flange geometry, seating stress, coolant composition, pressure and temperature.

TEADIT’s data-center application guide identifies NA1081 and NA1035 compressed-fiber materials for water and glycol services. A material’s suitability depends on the glycol formulation and additives, operating conditions and flange design; compatibility should be confirmed for the specific system.
TEADIT identifies Tealon TF1570 PTFE gasketing for ultra-pure-water (UPW) loops and for metallic and non-metallic flanges. Confirm the system’s purity requirements, operating conditions and joint design with application engineering before specifying a gasket.

A Technology Cooling System (TCS) delivers coolant to IT equipment to remove heat. A Facility Water System (FWS) transports chilled water between facility cooling equipment and the TCS. Gasket selection must address the coolant and joint conditions in the particular loop, rather than treating both systems as identical.
Reference: TEADIT explanation of TCS and FWS
Do not assume that a gasket selected for a water or glycol loop is suitable for a generator fuel or exhaust joint. Power-generation equipment can impose different temperature, pressure and thermal-cycling requirements. TEADIT identifies the 913M spiral-wound gasket among its power-generation sealing solutions; each joint requires application-specific selection.
Provide the flange material, dimensions and facing; coolant or process-fluid composition; operating and design temperature and pressure; available bolt load; and any purity or installation requirements. These inputs help an application engineer evaluate material compatibility, seating stress and joint reliability. A product name alone is not a complete gasket specification.

Power Usage Effectiveness (PUE) is the ratio of total facility energy to IT-equipment energy. TEADIT’s eBook explains that leaks, pressure instability and inefficient cooling can increase non-IT energy demand. Maintaining fluid-system integrity supports an overall efficiency strategy, but a gasket change alone does not establish a specific PUE improvement; results depend on the complete system and its operating conditions.

Small leaks can develop gradually and remain below monitoring thresholds. The eBook links persistent leakage with loss of cooling efficiency, pressure instability, additional pump load and increased maintenance. An absence of alarms is not proof that every joint is leak-free; inspection and maintenance should follow the facility’s approved procedures.

Repeated heating and cooling, pressure fluctuations and vibration can change the mechanical conditions of a sealed joint. Gaskets may relax or lose compression, bolt loads can change, and chemical exposure can degrade materials. TEADIT’s eBook recommends evaluating performance under real operating conditions rather than considering startup conditions alone.
Creep and relaxation can reduce gasket compression over time and contribute to leakage. Coolants and their additives can also affect material durability. The eBook identifies thermal resistance, chemical compatibility and sealability under low stress as selection factors. Evaluate these together with flange design and operating conditions; no single material is suitable for every cooling joint.

Yes. The eBook explains that installation variability can cause improper gasket compression, flange misalignment and uneven load distribution, even when the design specification is sound. Use the approved material, handling practices, installation procedure and joint-specific torque requirements. A universal torque value cannot be inferred from the gasket product name.
