NAI-LOK UHP Metal Face Seal Fittings Double Male Union Metal Gasket Face Seal Fittings For Ultra High Purity Systems
The NAI-LOK UHP Metal Face Seal Fittings are precision-engineered double male union fittings designed specifically for ultra high purity (UHP) systems. Featuring a metal gasket face seal, these fittings ensure a reliable, leak-tight connection ideal for critical applications in semiconductor manufacturing, pharmaceutical, and analytical gas systems.
Constructed from high-grade stainless steel (SS316), the fittings provide excellent corrosion resistance, durability, and maintain integrity under high vacuum and high purity gas environments. The double male union design simplifies installation and maintenance, enabling secure connections between tubing and equipment with minimal risk of contamination.
These UHP face seal fittings are manufactured to meet stringent quality and cleanliness standards, ensuring compatibility with ultra high purity gas distribution systems. Their robust metal-to-metal sealing mechanism offers superior performance compared to traditional soft seals, making them the preferred choice for demanding industrial and laboratory environments.
