This durable polycarbonate pump dispenses directly from a 1 gallon (3.8 L) jar with an 120 mm neck opening. You should measure the outside diameter of your jar opening - including the threads, to determine the proper size needed. The stainless steel lid will sit over the jar threads.
Solution™ pumps are quite versatile in their ability to dispense a variety of thick, thin and even products with particulates. Unlike most plastic pumps, the Solution™ style pumps offer adjustable portion control, can be disassembled, are dishwasher safe and NSF listed. A 1 ounce (30 mL) serving is the maximum portion per stroke. Portions can be reduced in 1/4 ounce (7 mL) increments, using the supplied gauging collars.
