Clamp allows quick access to content inside the furnace. High-temperature silicon O-ring and centering ring at flange cap. 1\/4\" in diameter vacuum sealing assembly connects with rubber hose. Ideal for any type of tubing: ceramic, glass, quartz and steel pipe. Vacuum Level 10E-2 torr by a mechanical pump 10E-5 torr by a small turbopump and 10-6 torr by hi-speed turbopump Optional Parts For precision vacuum control up to 10 -4 torr, please choose our Digital Vacuum Gauge. (Fig.1) For CVD application, please choose our Anti-corrosive Vacuum Gauge. (Fig.2) We provide various Fitting Ends for separate purchase. (Fig.3) For advanced control over gas flow, please choose our Float-meter. (Fig.4) The product requires flange support, please consider our Adjustable Tube Support. (Fig.5) Warning A refractory tube block is required in front of the flange to avoid silicone O-ring melting. Please consider purchasing our ceramic tube block This product is heavy, flange support is required to avoid damage on the furnace tube.
