This is a custom dispensing component. Neck finish, target output, actuator lock, viscosity range, dip-tube length, formula compatibility and transport leakage require sample testing.
Checks before sampling
Match the component to the exact bottle neck finish or approved finish drawing, not diameter alone.
Confirm formula viscosity, target output, actuator or spray pattern, dip-tube length and filling method.
Validate priming, leakage, lock or overcap function and transport handling with the final bottle system.
Application and sizing guide
Lock-down lotion pump transport planning
The lock-down lotion pump is planned for shampoo, conditioner, body lotion, hand wash and similar personal-care bottles. Compare 24/410 and 28/410 versions by output, down-lock travel, actuator clearance, viscosity range and dip-tube length, then test whether the locked pump remains secure through packing and transport.
