DupakSYS 5-Gallon Pump Dispenser 2-Pack 38/400 — 1 oz Dose, 50cm Extended Tube, Drip-Prevention Caps

DupakSYS 2-pack 5-gallon pump dispensers are heavy-duty 38/400 pumps that deliver 1 ounce (30cc) per press, with extended 50cm tubes and drip-preventing caps for large jugs and buckets.

These replacement pumps are built to convert large containers — five gallon jugs, 1-gallon bottles and many standard buckets — into convenient, measured-dispense stations. Crafted from robust, washable plastic with a rapid retraction mechanism, each pump dispenses a consistent 1 oz per press and includes both short and extended tubing so you can reach the liquid at the bottom of deep containers. Two cap covers are included to limit drips after use.

How do these pumps ensure consistent dosing?

Each DupakSYS pump is engineered to release approximately 30cc (1 ounce) with every full stroke, which makes portion control simple and repeatable. The pump’s internal chamber and spring provide fast retraction so the next dose is ready without sticky delays.

• 30cc (1 oz) output per complete press for predictable dosing
• Rapid retraction mechanism for quicker follow-up presses
• Locking top on the neck to prevent accidental activation during transport

Will this fit my container and how do I customize the tube length?

These pumps are made to thread onto containers with a 38/400 neck (38mm). The set includes two 15cm tubes and two 50cm extended tubes; you can trim them to the exact length needed to reach the bottom of tall jugs or awkward containers.

• Fits 38/400 neck size (measure your bottle neck before purchase)
• Two tube lengths provided — 15cm and 50cm — for flexible reach
• Trim-to-fit tubing lets you adapt the pump to deep or shallow containers

How does the drip cap and nozzle design reduce mess?

Each pump includes a black tip cover designed to reduce dripping from the long nozzle after dispensing. If small amounts remain in the nozzle, tilting the head and allowing residual liquid to flow back before capping helps minimize post-use drips.

• Included cap covers block nozzle drips when the pump is idle
• Long nozzle and proper tilting reduce residual runs back into the container
• Ideal for slippery liquids where small residuals can otherwise cause mess

What liquids and environments are these pumps suitable for?

DupakSYS pumps are versatile and compatible with a wide variety of liquids used in homes, salons, garages, and commercial settings. They work well with shampoos, conditioners, hand soap, body wash, lotions, cleaning solutions, disinfectants, laundry detergents, oils and other non-corrosive fluids.

• Suitable for personal care liquids like shampoo and lotion
• Compatible with cleaning chemicals, detergents and oils (non-corrosive)
• Durable plastic construction supports repeated commercial or household use

Check your container neck measurement (38/400) before ordering to ensure compatibility, and enjoy a cleaner, more controlled way to dispense bulk liquids.
