8000S Primary/Secondary Closely Spaced TEE Solder
The 8000S Closely Spaced TEE sets the gold standard for hydraulic separation in primary/secondary loops, built to endure relentless 600 PSI WOG (Water, Oil, Gas) environments. Designed for industrial refineries, power plants, and mission-critical HVAC systems, this valve integrates a chrome-plated full-port ball between two precision-spaced tees, ensuring zero cross-contamination and flawless flow control. Its DZR lead-free brass body and solder connections deliver permanent, leak-free reliability in systems where failure is not an option.
Key Features & Benefits
- Industrial Pressure Dominance: 600# WOG rating—the highest in its class—handles extreme steam, oil, and chemical media in refineries and power generation.
- Soldered Perfection: Precision solder joints (ASME B16.18 compliant) ensure lifetime integrity, ideal for permanent installations in high-vibration or seismic zones.
- Arctic-to-Inferno Resilience: Operates from 15°F to 260°F (-9°C to 127°C) with antifreeze/anti-boil additives, perfect for cryogenic cooling or boiler systems.
- Decades of Sealed Performance: Blow-out-proof stem and virgin PTFE seats withstand 20,000+ cycles, even in abrasive or corrosive fluids.

Why the 8000S Reigns Supreme
This isn’t just a tee—it’s a fortress. The military-grade chrome plating resists scaling in superheated steam, while the solder joints offer unmatched durability where press-fit systems falter. Designed for engineers who prioritize permanence over convenience, it’s the definitive choice for systems demanding zero tolerance for leaks or downtime.
Note: Requires ASME-compliant soldering practices. Pressure-test all joints post-installation.
