There are many uses for taps and many containers with different fittings. Some containers have an external thread to suit a cap while others have an internal thread to suit a bung. We have both taps fitted with caps from 38mm to 71mm and taps with external ¾” BSP, 2” BSP, 56 x 4 Buttress and 70 x 6 Buttress threads.

What are Non-venting and Self-venting Taps?

When dispensing through a tap, the container needs to be ‘vented’ – air needs to get into the container – otherwise a vacuum will be created and the product will ‘glug’ out or be difficult to dispense. Often with the larger containers, there are two bungs opposite each other and when a tap is fitted to the one, the other can be opened to let the air in. With smaller containers or those with only one opening, you will need a self-venting tap. This lets air in at the same time as dispensing the chemical.
