DupakSYS 2-Pack Gallon Jug Pump Dispenser 38-400 Thread — Leak-Proof 7.5cc Dosing, Cut-to-Fit 265mm Tube

DupakSYS 2-Pack Leak Proof Gallon Jug Pump Dispenser is a set of heavy-duty 38-400 pumps that deliver 7.5cc per press, fitting standard 1-gallon and 1/2-gallon bottles for controlled, drip-free dispensing.

These replacement pump tops are built to work with 38mm-threaded (38-400) openings on common 64oz and 128oz containers. Each pump comes with a long, cut-to-fit tube and a snap-on cap for leak protection, making them suitable for salons, kitchens, laundries, workshops, and high-use household stations. The pair offers a budget-friendly way to convert bulk bottles of soap, lotion, shampoo, hand sanitizer, or cleaning solution into easy-to-use dispensers.

What sizes and bottle types do these pumps fit?

The pumps are designed for 38-400 threaded necks, which match many 1-gallon (128oz) and 1/2-gallon (64oz) jugs. The 265mm tubes are long enough for deep containers and can be trimmed to the correct length for shorter bottles. This makes them compatible with a wide range of personal care and household liquid containers.

• Standard 38mm (38-400) threaded neck compatibility
• Fits 64oz and 128oz gallon-style bottles commonly used for shampoo, soap, and cleaners
• 265mm tubing included; easy to cut for shorter bottles
• 7.5cc dispensed per pump stroke for consistent portions

How reliable is the pump for frequent, heavy use?

Constructed from sturdy plastic materials, these pumps are intended for repeated daily use in commercial and residential settings. The mechanism resists wear and the included caps reduce mess and evaporation when not in use. While robust, routine cleaning and avoiding highly abrasive or solvent-based liquids will prolong lifespan.

• Heavy-duty plastic construction for durability
• Leak-proof cap prevents drips and keeps nozzles clean
• Simple design for easy maintenance and occasional rinsing

How much liquid does each press dispense and why does that matter?

Each press delivers approximately 7.5cc of product, a measured amount that helps control usage and reduce waste compared with free-pouring from bulk jugs. Measured dosing is helpful in workplaces and homes where consistent portions improve cost control and reduce oversupply. If you need larger or smaller volumes, these pumps are inexpensive to replace with different stroke sizes.

• 7.5cc per pump for consistent dosing
• Helps limit product waste and standardize servings
• Easy to swap for other pump sizes if different volume is required

Can these pumps handle different liquids like shampoo, sanitizer, or cleaners?

Yes—DupakSYS pumps are multi-purpose and suitable for a broad variety of low- to medium-viscosity liquids including hand soap, lotions, shampoos, conditioners, sanitizers, massage oils, and many cleaning solutions. Avoid highly viscous pastes or strong solvents that may damage internal components. If using concentrated chemicals, test compatibility and rinse the pump after heavy-duty use.

• Works with soaps, lotions, shampoos, and sanitizers
• Not recommended for very thick pastes or aggressive solvents
• Rinse after use with harsh cleaners to protect pump parts

Who is this for? These DupakSYS 2-pack gallon pumps are ideal for business owners, salon professionals, facility managers, and households that use bulk liquids and need reliable, portion-controlled dispensing. They suit anyone who wants a tidy, cost-effective solution to make large containers user-friendly—especially high-traffic sinks, communal wash stations, laundry rooms, and cleaning supply closets. If you need a robust replacement pump that fits standard 38-400 jugs and reduces spills, this set provides practical value for frequent use.
