40/410 40mm Plastic Shampoo Brush Foaming Pump for Facial Cleanser Washing Dispenser Pump

How to Choose the Right 40mm Foaming Pump

1. Measure your bottle neck – Confirm the finish is 40/410 (or 40/400, 40/415). If uncertain, measure the inside diameter and thread pitch.

2. Match dosage to product – 0.4-0.8cc for standard hand soap; 1.2-1.5cc for thicker formulations or larger coverage.

3. Consider your formula – Ensure pump materials (spring type, gaskets) are compatible with your liquid (e.g., silicone gaskets for oily formulas) .

4. Choose locking style – Up-lock or clip-lock preferred for e-commerce and secure shipping .

5. Order dip tubes – Specify exact bottle height so tubes reach the bottom.

In short: A 40mm foaming pump—especially the common 40/410 size with 0.8cc output and up-lock mechanism—is the industry standard for foaming soap and cleanser bottles. If you are selling online, prioritize e-commerce capable models with secure locking features .
