AI is changing more than computing power. It is changing how data centers are cooled, powered, and engineered.
As facilities adopt liquid cooling and expand backup power infrastructure, one question is becoming increasingly important:
Why does sealing matter?
The following questions explore the engineering challenges behind modern data center infrastructure and explain why sealing has become a critical factor in maintaining uptime, efficiency, and long-term reliability.
1: Why are liquid cooling systems creating new sealing challenges?
Liquid cooling circuits contain hundreds, sometimes thousands, of gasketed joints connecting cooling distribution units (CDUs), heat exchangers, pumps, valves, and piping.
Unlike traditional industrial systems, many of these assemblies utilize lightweight, thin-wall stainless steel manifolds and HDPE piping, which often provide lower flange rigidity and reduced bolt loads.
This means sealing materials must perform reliably under lower seating stresses while resisting creep, thermal cycling, and having chemical compatibility with a variety of cooling media.
Engineering Insight: Products such as Tealon® TF1570 are designed to provide exceptional creep resistance and broad chemical compatibility, making them well suited for glycol, ultra-pure water (UPW), and process cooling applications where long-term joint integrity is essential.
2: How can poor sealing affect data centers' power usage effectiveness (PUE)?
The most immediate risk is physical: liquid cooling places fluid-carrying joints directly above and alongside energized IT equipment. Even a small leak that reaches servers, power distribution, or cabling can turn a minor sealing failure into damaged hardware and an unplanned outage.
Leaks also carry longer-term costs. Coolant losses require makeup fluid, which over time dilutes glycol and corrosion inhibitors and degrades heat transfer performance, increasing pumping energy and eroding Power Usage Effectiveness (PUE). Reliable joints help cooling systems operate as designed while supporting lower operating costs.
3: Why is sealing just as important for backup power?
Cooling systems only protect uptime if electrical power remains available.
Emergency diesel generators, gas turbines, and hydrogen-ready power systems operate under extreme temperatures, pressure fluctuations, vibration, and repeated thermal cycling.
These demanding conditions require sealing materials capable of maintaining bolt load and leak-tight performance throughout years of service.
Engineering Insight: TEADIT® 913M spiral wound gaskets are engineered for high-temperature applications requiring exceptional blowout resistance and reliable torque retention, making them well-suited for critical power generation equipment.
4: What should engineers consider when selecting a gasket?
Pressure and temperature ratings are only part of the equation.
Reliable sealing depends on evaluating the complete joint assembly, including:
For cooling systems utilizing dielectric fluids or water-based circuits, TEADIT® NA1081 provides excellent chemical compatibility and resistance to creep, helping maintain reliable sealing performance over extended operating periods.
5: What role does TEADIT® play?
Modern data centers require more than an average gasket supplier.
TEADIT® delivers engineered sealing solutions supported by application engineering, material selection, flange management, technical support, and complementary joint components including bolting, hoses, and expansion joints.
Its engineering-first approach helps operators improve cooling efficiency, strengthen backup power reliability, reduce maintenance, and protect the uninterrupted operation that mission-critical facilities demand.
Key Takeaway
The future of AI infrastructure depends on more than processors and cooling equipment. It depends on every mechanical joint performing reliably under demanding operating conditions.
