Permabond Data Center Sealants & Adhesive Solutions
Permabond manufactures data center sealants suited to the demanding conditions in modern AI data centers. The main job of these sealants is to seal liquid coolant pipe connections. Since any coolant leak poses catastrophic, costly damage to sensitive server hardware, product selection is a critical decision in this industry, not an afterthought.
AI servers consume on average ten times as much energy as traditional servers, generating substantially more heat. This escalating thermal load has driven a fundamental shift in thermal management strategies, from air cooling to liquid cooling systems, where water-based coolants remove heat thousands of times more efficiently per unit volume than air. In these architectures, liquid cooling works in concert with heat sinks, drawing heat away from components with far greater capacity than passive or fan-assisted air solutions alone can achieve. Permabond’s range of anaerobic pipe sealants is ideally positioned to support this evolving infrastructure, ensuring the integrity of every connection in the liquid cooling loop.
Typical applications of Data Center Sealants & Adhesives:
- Sealing liquid coolant pipe connections in direct-to-chip cooling loops
- Sealing connections in immersion cooling tank pipework
- Thread sealing on brass and stainless steel fittings
- Preventing leaks in closed-loop coolant circuits under vibration and pressure
- Bonding thermal interface components to heat-generating hardware
- Sealing glycol-based or dielectric coolant circuits
Although sealing coolant lines in data centers is a relatively new undertaking, Permabond MH052, our go-to product for this industry, has a long history. It is trusted by manufacturers in the commercial refrigeration industry – just as with data center coolants, MH052 works very effectively with refrigerants. Its BAM approval also makes MH052 trusted for use in the medical field, and its WRAS approval makes it safe for applications involving contact with drinking water.
All of these applications for anaerobic sealants come naturally to Permabond, since we are already a leading provider of anaerobic pipe sealants to the fire protection market. The fire protection industry demands the very highest standards of pipe joint integrity – when failure could literally cost lives, your product has to live up to the highest standards of rigor. That same zero-tolerance approach to leaks is exactly what data center operators want when protecting millions of dollars’ worth of AI server hardware from coolant leakage.
Why is pipe sealing so critical?
Leak Prevention – Coolant leaks can cause irreversible damage to server hardware. A watertight, durable seal is the first line of defense for expensive AI infrastructure.
Thermal Cycling – Pipes face constant heat from server equipment and cold from coolants. Sealants must remain flexible and intact through repeated expansion and contraction cycles.
Chemical Resistance – Modern coolants contain glycols and corrosion inhibitors. A quality sealant must maintain performance when exposed to these fluid chemistries over time.

FEATURED PRODUCT
Permabond MH052 — Anaerobic Pipe Sealant
MH052 is a high-performance anaerobic sealant specifically suited for sealing liquid coolant pipe connections in data center applications. It creates a fast, low-pressure seal and cures into a chemically resistant polymer that prevents leaks even under vibration, pressure, shock, and contamination. Unlike PTFE tape, MH052 will not shred over time, and unlike pipe dope, it will not dry out, thus providing a long-lasting, durable joint.
Key features of Permabond MH052:
- Fast low-pressure seal on application; full cure in 24 hours (can be accelerated with Permabond ASC10)
- Withstands vibration, pressure, and mechanical shock
- PFAS-free formulation; meets tightening regulatory standards
- BAM approval for use with gaseous oxygen
- WRAS approval for contact with drinking water
- No drying out (unlike pipe dope)
- Joints maintain integrity long-term
- Excellent bonds to stainless steel and brass fittings
- Chemical resistance to glycols and corrosion inhibitors in modern coolants
- No shredding (unlike PTFE tape), no contamination of coolant loops
- Accordion pack improves handheld application, no special equipment required
