Product Description
NAI-LOK High Pressure 6000psi 1/16" to 2" Stainless Steel 316L Reducing Union Double Ferrule Tube Fitting
Premium High-Pressure Compression Fitting for Demanding Industrial Applications
The NAI-LOK High Pressure Reducing Union is engineered for superior performance in extreme-pressure instrumentation, hydraulic, and pneumatic systems. Featuring a double ferrule compression design, this fitting ensures a leak-proof, vibration-resistant seal, making it ideal for critical applications in oil & gas, chemical processing, petrochemical, and power generation industries.
6000 PSI (414 Bar) Pressure Rating - Withstands extreme high-pressure environments for reliable operation.
Double Ferrule Compression Design - Provides a secure, leak-free connection resistant to vibration and thermal cycling.
Corrosion-Resistant Materials - Constructed from Stainless Steel 316L, with optional premium alloys including 6Moly (S31254), HASTELLOY® (C22, C276, B3), Titanium, Nickel Alloys, INCOLOY® (825, 800), MONEL® 400, INCONEL® 625, and Super Duplex (S32750, 2507, 2205) for superior resistance to acids, chlorides, and seawater.
Precision Machined for Optimal Flow - Smooth internal bore minimizes pressure drop and ensures turbulence-free fluid/gas transmission.
NPT Thread (National Pipe Tapered) - Ensures a tight, pressure-resistant seal with standard piping systems.
BSPP,BSPT,SAE THREAD
1/16" to 2" Reducing Union - Compatible with a wide range of tubing sizes for flexible system integration.
Wide Industry Applications - Perfect for instrumentation tubing, process control, chemical injection, and high-pressure fluid/gas transfer.
