Fujikin UPG-9.52N Union Nut for High-Performance Ultra-Compact Gasket Fittings
UPG-9.52N is a union nut used in Fujikin's UPG® high-performance ultra-compact gasket fitting system. In the model designation, “9.52” indicates the nominal 9.52 mm tube size, corresponding to 3/8", while “N” identifies the component as a union nut. The UPG® series is an ultra-compact precision fitting system developed from Fujikin's conventional UJR gasket fittings. It has been reduced to approximately 70% of the UJR size and incorporates features such as separation of the sealing section from external-force-bearing areas, full-surface sealing contact and an over-tightening prevention mechanism.
Product Details
Product Features
Ultra-Compact Design: The UPG® system is approximately 70% of the size of conventional UJR fittings, supporting high-density piping layouts.
Stable Tightening: Full-surface contact helps stabilize tightening torque and enables controlled assembly.
SUS316 Construction: The UPG-9.52N union nut is made from SUS316 stainless steel for precision gas and fluid piping applications.
For 9.52 mm Fittings: Specifically designed for Fujikin UPG 9.52 mm (3/8") fitting assemblies.
Over-Tightening Prevention: The UPG design incorporates an over-tightening prevention mechanism to help protect the sealing section during assembly.
Suitable for Clean Piping Systems: Compact and low-dead-space construction supports applications requiring high cleanliness and reliable sealing.
Product Applications
Semiconductor Equipment: Suitable for high-purity and process-gas piping in semiconductor manufacturing equipment.
High-Purity Gas Systems: Suitable for nitrogen, helium and other gases compatible with the wetted materials.
Precision Fluid Equipment: Suitable for analytical equipment, laboratory systems and precision fluid-control assemblies.
Gas Supply Systems: Suitable for gas cabinets, gas panels and compact gas-distribution modules.
UPG Fitting Maintenance: Used as a replacement or assembly union nut for Fujikin UPG 9.52 mm fitting systems.
