ZJ Pack 18-410 PP Oil Pump for High-Viscosity Formulas with 0.23cc Dosage, Twist Lock & E-Commerce Shipping Clip

What this packaging is

An external spring design sets this pump apart — the spring sits completely outside the pump body, never touching the formula inside, which is why it's compatible with 95%+ of oil-based liquids. The 18-410 PP Oil Pump for High-Viscosity Formulas delivers a precise 0.23cc dose per stroke with a twist-lock mechanism that prevents accidental discharge, plus an e-commerce shipping clip built for direct-to-consumer fulfillment. Made from durable polypropylene with a glossy collar finish, it fits standard 18-410 neck finishes and suits face serums, beard oils, hair oils, cuticle oils, and cleansing oils — a clean, functional closure for oil-forward brands building a premium daily ritual.

Why brands choose this

• Oil-safe engineering that most pumps can't match: The external spring design keeps the spring fully isolated from the formula, making this pump compatible with over 95% of oil-based liquids — a meaningful technical advantage for pure facial serums, cleansing oils, and beard oils where standard pumps can degrade or clog.
• Precision dosing plus transit-ready security: A consistent 0.23cc output per stroke gives consumers controlled, mess-free application, while the twist-lock mechanism and included e-commerce shipping clip prevent leaks and accidental discharge — a practical combination for brands selling direct-to-consumer or through third-party fulfillment.
• Decoration flexibility that supports elevated brand positioning: Compatible with electroplating, spray coating, and water transfer printing, this pump can be customized to match a brand's visual identity — important for oil-focused categories like face serum and hair oil, where premium shelf presence and ritual cues strongly influence purchase decisions.
