The Series 4703-4714 are the smallest of the Parr General Purpose Pressure Vessels. They have a 1-inch inside diameter and are offered in two different lengths with volumes of 22 and 45 mL.
These vessels have a flat PTFE gasket that is sealed with a screw cap. Special wrenches and bench sockets are offered for tightening these closures. The screw caps and bodies are made of alloy steel for use at temperatures to 300 °C. The maximum working pressure is 1700 psi (115 bar). The standard material of construction for these small, inexpensive vessels is Type 316 Stainless Steel, but they are also available in all of the current materials of construction Parr provides.
There is room for a single opening on the head of these vessels. This is generally an “A” socket which will accept a 4316 Gage Block Assembly. These heads can also be furnished with 1/8″ NPT, 1/4″ NPT, or a rupture disc assembly.
These vessels are normally heated in ovens, baths, or similar general purpose heating devices. Special heaters for these vessels are not available from Parr.Contact Us
