This Swagelok® Ultra-Torr® vacuum fitting union elbow connects two 3/8" OD tubes at a 90 degree (right) angle. Swagelok Ultra-Torr fittings are designed for vacuum system use only and offer reliable vacuum sealing performance up to ultra-high vacuum, even after repeated connects and disconnects. Ultra-Torr fittings are constructed of 316 stainless steel and use a knurled nut for easy, finger-tight assembly. No tools are required to assemble or disassemble the fittings. Unlike standard Swagelok compression fittings (used for both vacuum and pressure applications), Ultra-Torr fittings do not use a permanently swaged ferrule on the end of a tube. Instead, the seal is made by compressing an O-ring on the tube end. Because a ferrule is not used, these fittings can repeatedly seal glass, metal or plastic tubing without permanent alteration to the tubing.
