Comfort Axis Replacement Pump for 38-400 Bottles — Down-Lock Dispensing Pump, Trim-to-Fit Dip Tube (1 Each)

Comfort Axis replacement pump converts 16 or 32 oz 38-400 neck bottles into a drip-free, twist-lock dispensing system for paints, soaps and liquids.

This replacement down-lock pump is designed to fit bottles with a 38-400 (38 mm / 1.5 in) neck finish and turns large containers into easy-to-use dispensers. It’s a practical swap-in for art studios, classrooms, salons and home-care uses where pouring is messy or inconvenient. The pump features a locking twist to prevent accidental dispensing and a trim-to-fit dip tube so it works with both tall jugs and shorter bottles.

Will this pump fit my bottle?

Check your container’s neck diameter and thread style before ordering: this pump fits only 38-400 (38 mm / 1.5 in) neck finishes. The 38-400 designation is two-part: the first number is the inside opening diameter in millimeters and the second describes the thread style and skirt depth.

• Compatible with 38-400 necks (38 mm / 1.5 in).
• Not suitable for other neck sizes — measure to confirm fit.
• Trim the dip tube if your bottle is shorter than 11 inches from lid to bottom.

How does the pump make dispensing safer and cleaner?

The down-lock dispensing head prevents drips and keeps work surfaces tidy by allowing single-hand, controlled pumping instead of pouring. A twist-lock mechanism secures the head for storage or transport to avoid spills and contamination.

• Locking head prevents accidental leaks during storage or transport.
• Controlled pumping reduces over-dispensing and waste.
• Ideal for messy workflows like painting, gluing or refilling smaller bottles.

Can I use this pump for products other than paint?

Yes — this style of pump is versatile and widely used across personal care, pet care and household products. It works well with shampoos, conditioners, lotions, body washes, syrups, condiments, adhesives and more, provided the liquid’s viscosity is compatible with a standard down-lock pump.

• Commonly used for lotions, soaps, shampoos, and adhesives.
• Not recommended for extremely thick gels without testing first.
• Reusable and compatible with many 16/32 oz refillable containers.

What are the pump’s dimensions and modification options?

The pump assembly measures approximately 13.5 inches from top to the full dip tube and about 11 inches from the lid to the tube’s end, which suits most standard jugs. You can trim the dip tube to fit shorter bottles without affecting the locking head or pump action.

• Cap size: 38-400; lid diameter: 1.5 inches.
• Pump length: 13.5 inches (can be trimmed); lid-to-bottom tube length: 11 inches.
• Sold individually — one pump per package.

Who is this for? This Comfort Axis replacement pump is ideal for teachers, artists, salon and facility managers, DIY crafters, and anyone who refills smaller bottles from larger containers. If you need a spill-reducing, lockable dispenser that works with 38-400 necked 16 or 32 oz bottles, this pump offers a simple, economical upgrade to streamline dispensing and protect workspaces.
