Single Shutoff and Shipping Plug System

A typical closed system will involve installing a dip-tube or "drum insert" at the DEF packaging facility. This dip-tube travels with the container to the end user facility. A coupler or "dispense head", is then connected on-site to the dip-tube for dispensing purposes.

Single shut-off & shipping plug systems (DrumQuik PRO)

In this type of closed system a shipping plug seals the dip-tube during transport and disposal

PRO’s:

  • Dip-tube is never handled by the end user thus eliminating a significant potential source of DEF contamination
  • 100% closed during critical transport, dispense and disposal

  • Shipping plug removal wipes critical sealing surface clean of any dirt, dust, etc. for a contamination free connection

  • Ideal for cost sensitive single-trip/one-way applications

  • Well suited for reusable/refillable applications

  • The lowest cost system. More rugged and less prone to leaks than plastic valve style dip-tube systems and much less costly than stainless systems

  • Works with standard tamper evident cap seals

CON’s:

  • There is the potential to lose a shipping plug. This is easily remedied by using a tether or keeping an inexpensive spare plug available.
