The tip may be machined from stock as a unitary piece, to increase its lifetime, and may be formed with a bore of a relatively large diameter that is tapered down to a smaller diameter near the tip opening, to allow for delivery of fluid through the tip body at a decreased pressure. A cleaning tool may be provided for removing residual material from the inner surfaces of the tip. A removable liner sleeve may be provided within the bore to reduce the effective inner diameter of the dispense tip. | 03-24-2016 |
