Our step brass hollow sleeve is a fully custom CNC turning machined component fabricated from seamless brass tube raw stock. The base raw material is 6mm outer diameter brass tubing with a 4mm through inner bore, processed on high-precision CNC turning equipment to turn one segment down to a 5.5mm outer diameter stepped section.
After mechanical CNC turning processing, every brass component undergoes full degreasing ultrasonic washing to eliminate machining oil residues, then chemical passivation treatment to boost brass corrosion resistance and preserve its metallic luster long-term.
As a dedicated CNC machining manufacturer, we deliver full OEM custom service for this brass sleeve and all similar tubular brass fittings. We welcome clients to submit custom engineering drawings or physical samples for bespoke dimension, tolerance, surface finish modification to match unique industrial equipment assembly requirements.
