DupakSYS 4-Pack Gallon Jug Pump Dispensers 38-400 Thread – Leak-Proof 7.5cc Metered Pumps with Cap & Trim-to-Fit Tube

DupakSYS 4-pack 38-400 gallon jug syrup pump dispensers are leak-resistant, heavy-duty plastic pumps that fit standard 1-gallon and half-gallon jugs to deliver a measured 7.5cc per press.

These DupakSYS pumps convert bulky refill jugs into easy-to-use dispensers for syrup, soap, shampoo, detergent, lotion, and more. Built from robust plastic with a cap to prevent drips, each pump comes with a 265mm tube you can trim to suit bottle height. The 38-400 thread pattern matches common gallon and half-gallon containers, making these a practical upgrade for home kitchens, salons, cafés, or janitorial closets.

How reliable are these pumps for everyday use?

Each pump is molded from heavy-duty plastic engineered for repeated cycles without bending or breaking. The mechanism provides consistent portioning and the included cap prevents accidental dripping when not in use. They’re designed for frequent commercial or household use without immediate wear.

• Durable construction resists repeated pressing and everyday handling
• Leak-proof cap closes over spout to stop drips during storage or transport
• Consistent 7.5cc dose reduces over-pouring and waste

Will these fit my 1-gallon or 64oz container?

The pumps use a standard 38-400 thread collar that fits most 1-gallon and half-gallon jugs with a 38mm opening (measured including the thread). Each pump includes a 265mm tube you can cut to the correct length for 64oz or 128oz bottles. Always verify your bottle’s thread size before purchase to ensure compatibility.

• Standard 38-400 thread matches most gallon and half-gallon refill containers
• 265mm tube can be trimmed to fit shallow or deep bottles
• Designed for 64oz and 128oz containers commonly used for shampoo, syrup, and detergent

How much liquid is dispensed per pump and does it control waste?

Each press dispenses approximately 7.5cc of liquid, offering repeatable metering that helps prevent overdosing. That measured delivery is useful for recipes, retail service counters, and controlled dispensing of concentrated cleaners or personal-care products. The consistent shot size saves product over time compared with free-pouring from a jug.

• Exact dispensed volume: ~7.5cc per press for predictable portioning
• Useful for syrup servings, hand sanitizer, lotion, and dosing concentrated cleaners
• Minimizes waste and keeps work areas cleaner than pouring

Are these pumps easy to clean and maintain?

Maintenance is simple: rinse the tube and nozzle with warm water and cycle a safe cleaning solution through the pump if needed. The plastic construction resists most household cleaners, and the removable tube and cap make access straightforward. Routine rinsing prevents buildup from viscous fluids like syrup or conditioner.

• Removable tube and nozzle for straightforward rinsing and flushing
• Cap protects spout from dust and drips between uses
• Compatible with water-based cleaners for periodic sanitizing
