As data center demands surge and liquid cooling becomes the standard, efficiency and uptime are everything. At 4-STAR Hose, we don’t just supply top-tier Gates OCP Universal Quick Disconnect (UQD) couplings—we bring decades of hose system expertise, custom assembly services, and rapid support to ensure every installation is right the first time. Whether you’re planning a retrofit or scaling out your infrastructure, our team helps you streamline and future-proof your cooling loop.
1. Compact Design for Dense Rack Configurations
Gates UQDs are designed for tight spaces without sacrificing performance. Their minimal footprint maintains robust coolant flow, giving you better thermal control in high-density server environments.
2. Dry-Break Functionality Keeps Systems Running
No tools. No mess. No downtime. These couplings enable safe, leak-free disconnections—ideal for live maintenance, system upgrades, or quick hardware swaps, all without shutting down your liquid loop.
3. Built for Rugged Performance
Gates UQDs are constructed from 316 stainless steel with EPDM sealing and built to handle extreme conditions—operating from –40°F to 248°F and withstanding pressures up to 290 psi (burst-rated to 1,160 psi). Choose from four UQD sizes to perfectly match your rack and system requirements.
4. Fully OCP-Aligned for Seamless Integration
OCP-compliant and built for modern modular deployments, Gates UQD couplings pair easily with Data Master Cooling Hose and Megaflex assemblies—making them a natural fit for today’s scalable data center designs.
5. Why Partner with 4-STAR Hose?
As a trusted Gates distributor, 4-STAR Hose goes beyond the sale:
- Custom UQD hose assemblies to your spec
- Fast turnaround with local stocking and service
- On-site support & delivery in key regional hubs
- Technical consultation to ensure right-fit sizing and compatibility
FAQs: Gates UQD Couplings & Data Center Cooling
Q1: What makes Gates UQD couplings better than traditional quick disconnects?
Gates UQDs are engineered with true dry-break technology, allowing for tool-free servicing without coolant leaks or pressure loss. Their compact design and high-flow performance are specifically built for modern, space-constrained data centers.
Q2: Are Gates UQD couplings compatible with other cooling components?
Yes. UQDs are Open Compute Project (OCP) compliant and pair perfectly with Gates Data Master Cooling Hose and Megaflex lines, making them plug-and-play within OCP-standard environments.
Q3: Can 4-STAR Hose provide custom UQD assemblies?
Absolutely. We offer custom-fabricated assemblies using Gates UQD couplings, built to your exact specifications and rack layout needs. Our in-house crimping and testing services ensure fast turnaround and quality you can trust.
Q4: How do I know which UQD size is right for my rack system?
Our team can help you determine the right size (UQD02 through UQD08) based on your flow rate, coolant type, and system layout. We also provide technical support and sizing consultation at no extra cost.
Q5: Can I use UQDs in retrofit cooling systems?
Yes. UQDs are designed for both new builds and retrofits, and their flexible installation profile makes them ideal for upgrading legacy cooling infrastructure without major redesigns.
Q6: What’s the lead time for UQD assemblies through 4-STAR Hose?
Most orders ship fast—with local stock and same-week fulfillment available on standard sizes. Contact us for current availability or large-scale project planning.
