Brochure Fujikin UJR Series

UJR gasket vacuum connectors are precision union tube connectors in which the tube is welded to the sleeve, a metal gasket inserted between the sleeve edge seal and the body seal and the structure sealed with a union nut.

The four main structural parts, the body, sleeve, union nut and gasket, are all manufactured of stainless steel 316 (SUS316) or 316L.

Features and Applications

-Use of the Pure Ring prevents twisting during tightening and improves sealing performance remarkably. Also, torque reducing effect increases working efficiency.

-Space along the axis is not required for connection and disconnection thus enabling working in tight spaces.

-High precision finishing of the sealing surfaces of the body and sleeve ensures high air tightness even though it is a metal seal.

-Superior corrosion resistance and pressure resistance extends applications from high vacuums and high temperatures to extremely low temperatures. Maximum gasket working temperature is 1004° F (540°C) for FSUS316 stainless steel and 1400°F (760°C) for nickel made.

-Can be safely used resisting impact pressure and vibrations.

-Union nut threads are silver plated, thus preventing thread seizure.

-Tube size is indicated on the sleeve for quick confirmation.

-All connectors are packed in a clean environment following degreasing treatment, thus enabling immediate use applications where oils and greases are prohibited.
