NAI-LOK 3/8" Stainless Steel Compression Union Tee | SS316 Double Ferrule Tube Connector
NAI-LOK 3/8'' OD Union Tee Tube Fittings is designed for reliable and leak-free three-way tube connections in instrumentation, hydraulic, and gas control systems. Manufactured from high-quality stainless steel SS316 / SS316L, this fitting provides excellent corrosion resistance, high strength, and long service life in demanding industrial environments.
The double ferrule compression design ensures secure tube gripping, vibration resistance, and superior sealing performance under high pressure conditions up to 6000 PSI. The tee structure allows fluid or gas distribution in three directions, making it ideal for complex piping and instrumentation systems.
Compared with welded or threaded tee fittings, the compression tee tube fitting offers easier installation, better flexibility, and reduced leakage risk.
NAI-LOK stainless steel tube fittings are precision machined to ensure tight tolerance, consistent quality, and reliable field performance.
