Polyethylene nozzles securely thread into all Optimum cartridge sizes, 725 Series piston valves, and 736HPA-NV high pressure valves.

Each comes with a 1/4 NPT (6.35 mm) thread and is manufactured using the highest-quality materials.

Nordson plastic nozzles are manufactured and quality-tested to be free of molding flash - bits of plastic that can block fluid flow and cause inconsistent deposits.

All Optimum dispensing tips are manufactured in the USA in silicone-free facilities to prevent fluid contamination and are certified for industrial use
