High density and high hardness: A higher density equals longer lasting than most other material. These abrasive oil spray nozzles are compacted with a premium tungsten carbide material for a higher density of 15.0-15.1g/cm³!
Corrosion resisted and high temperature resisted : This property make it a long service lifespan under multiple bad working conditions.
Precise thread: Our oil spray nozzles thred are professionally manufactured by special thread grinding lathe,which could be aseembly more precisely and stably.
