特点
● Connecting equipment and fittings with GL threads with hard-walled tubing or tubes made of glass, plastic or metal.
● Fixing probes, thermometers, dip tubes or cables in reaction vessels.
● Black screw caps made of PPS, inner parts consisting of a v-ring （PPS）, a tapered ring and a sealing ring （both PTFE） as well as an o-ring （FKM） for tubing diameters under 3mm （not exposed to the medium）.
● Good chemical resistance, the medium is only exposed to PTFE.
● Temperature resistant from -50 to 250°C, pressure stable up to 10 bar, suitable for vacuum.
● 可将带GL螺纹的设备和接头连接到玻璃、塑料或金属制的硬质管或软管上。
● 可用于固定反应容器内的探头、温度计、插管或电缆。
● 黑色螺旋盖采用PPS材质，内部组件由V形环（PPS）、锥形环、密封环（两者均为PTFE），以及适用于直径小于3mm的管（不接触介质）的O型圈（FKM）构成。
● 具有良好的耐化学性，介质仅与PTFE接触。
● 耐热范围为-50～250°C，耐压可达10bar，适用于真空环境。
