Seems to work great

Cleans good but I don't do blasting for a living. I just wanted the best & longest lasting cause I don't plan on every wearing out or fooling with it again. Its a really nice nozzle but I only blast 5 hours a month. I'm knocking on 61 years old and I hope it last past the time I forget what blasting even means. All I can say I Blue Dog has treated me right the 5 times or so I have ordered and they was my 1st choice on this nozzle. Their prices have been fair and service has been fast. Thanks and if and when I need something else blast wise I will check Blue Dog 1st.


Boron Long Venturi Nozzle – Kennametal BLVE series nozzle. The same as our Tungsten Carbide Long Venturi and our SiALON Long Venturi Nozzles in size and shape.  They have the same 1″ entry in a flanged design, otherwise known as a “Wide Entry” Nozzle with 1-1/4 inch NPSM thread (Contact us to order in contractor thread).  The big difference is that they are made with Boron, one of the hardest refractory metalloids.  If you remember from the Nozzle Material Guide in our learning center, Boron lasts 5 to 10 times longer than the SiALON and Tungsten nozzles.  That means these nozzles will last 5-10 longer but they don’t cost 5-10 times more!  Since they are long Venturi, they offer a 40% increase in production over a straight bore nozzle.

All of these nozzles have aluminum 1-1/4 threads and a aluminum jacket.  It is NOT recommended to use an aluminum nozzle holder with these brass threaded nozzles.  Instead, please consider purchasing a Nylon Nozzle Coupling with 1-1/4 threads or an Brass Nozzle Coupling with 1-1/4 threads (coming soon) to accommodate these nozzles.

For replacement washers, please use 10-123 (It is meant for 1″ Wide Entry Nozzles).

Kennametal’s BLVE series Boron nozzle is great if you are blasting with silicon carbide, steel grit, or aluminum oxide.  Although these nozzles will handle those hard materials better, they are also more fragile so please don’t drop them.  If the blast nozzle you need is not in stock, Contact Us to place your order.
