* **Conical plugs** in Araldite cells, sealed with Apiezon N vacuum grease, have been designed and extensively used by Frossati. In small sizes (about 1 to 2 cm, the conical plugs withstand pressures differences of about 40 bar. Diameters of 4 to 6 cm have been used at low pressures (mixing chambers). Both parts of the cone (plug and seat) have to be machined using the same angle, essentially made at the same time. | * **Conical plugs** in Araldite cells, sealed with Apiezon N vacuum grease, have been designed and extensively used by Frossati.
