ZJ Pack 24-410 PP Slim Oil Pump with Nozzle Cap, 1cc Dosage with External Spring, Compatible with High-Viscosity Formulas

What this packaging is

An external spring design keeps the mechanism completely separate from your formula — a critical detail when you're dispensing pure oils. The 24-410 PP Slim Oil Pump with Nozzle Cap delivers a precise 1cc dose per stroke and is engineered to handle high-viscosity formulas, with compatibility across 95%+ of oily liquids. Built from polypropylene with a twist-lock nozzle cap, the slim actuator and glossy collar give it a clean, functional look on shelf. The 24-410 neck finish makes it broadly compatible with existing bottle ranges. Manufactured in China with a four-week production lead time, it's a practical choice for body oils, hair oils, cleansing oils, massage oils, and hair treatments where dosing precision and formula integrity are non-negotiable.

Why brands choose this

• External spring keeps mechanism out of your formula: For oil-based products, spring contact is a real contamination risk. The external spring design on this pump sits entirely outside the pump body, protecting formula purity — a meaningful engineering choice for brands working with pure body oils, cleansing oils, or sensitive hair treatments.
• Engineered for oils, not just tolerant of them: Most standard pumps struggle with high-viscosity, pure oil formulas. This pump is purpose-built for them, with confirmed compatibility across 95%+ of oily liquids — removing the guesswork during development and reducing the risk of costly pump-formula mismatches at production scale.
• Precise 1cc dosing supports product-use ritual and waste reduction: Controlled dosing is increasingly important to consumers and brand sustainability narratives alike. A consistent 1cc stroke gives users a repeatable application experience — especially relevant for premium body and hair oil brands where the sensory ritual and perceived value are tied directly to how the product dispenses.
