Care & Use:
These have a stainless steel spring for trigger sprayer. If you use highly corrosive substances, eventually it will corrode. These are made with the highest quality available chemical resistant plastic. However, any plastic will degrade over time if using harsh chemicals. That's why you need spares!
Instructions: You can trim dip tube to desired length. Just remove filter tip, trim, then replace filter tip on new end.
