This is a pair of smart sealing assemblies for a tube vacuum furnace to tighten both ends of OD 1" (25-26 mm) tube without any welding and gluing.

SPECIFICATIONS

Package included	A pair of flanges with 4 high-temperature silicone O-rings(300°C Max.) and 1 mechanical gauge One flange has a feedthrough for a 1/4" thermal couple.
Features	Made of Stainless Steel with 2 high-temperature silicone O-rings (300°C Max) on each flange. (for both sides order) Seal tube by tightening screws on the flange without any welding and glue. 1/4'' diameter stainless steel gas inlet/outlet fitting for PVC hose tube (tube not included).
