Reusable Graphite nozzles for Experimental use in Loki Research 38mm hardware.
Please specify nozzle number or throat size #11 thru #15 or 0.160" thru 0.245" in the comments section at checkout.
Made from a premium grade, high strength, high thermal conductivity isomolded fine grain graphite with excellent resistance to thermal shock and erosion. Its low porosity and smoothness make cleaning metal slag from the surface a breeze for re-use compaired to other types.
Why the extra cost? These are the smallest throat sizes we offer. Being so small, they require more tedious setup work with very small tools in extremely tight spaces and time = $. The exit cones also need to be opened up on about half of these sizes to get a decent expansion ratio, and all this work takes much more time than the larger sizes.
Throat IDs are bored out from standard #10 commercial throat sizes and the entrance is re-radiused.
