Virtually Zero Spillage

and Durable

The rail industry handles many different fluids and gases each day. TODO has developed a range of products ideally suited for these demands, be it direct refuelling or transferral of a locomotive’s load.

One of the most popular products in TODO’s rail range is the TODO-MATIC, a versatile dry-break coupling that has a maximum working pressure of up to 25 bar and is available in 1-6” sizes. However, most of our rail customers use either 2” or 3” units. The TODO-MATIC can be made from aluminium, brass or stainless steel – this ensures the most appropriate material is matched to its intended application.

The TODO-GAS Dry-Break Tank Unit is an ideal solution for rail customers handling LPG. This unit is specifically designed for loading/ unloading of both liquid and gas phases and is available in 1” and 3” sizes. High-grade stainless-steel construction ensures long repeat-use without reliability issues, even when handling the strongest chemicals. The TODO-GAS range is fitted with 90 Shore O-rings as standard to withstand the harsh conditions during LPG transfer.

Safety Pressure Tight Caps (PTCs) are another popular product in TODO’s rail range. These units are air-tested at working pressure of 25 bar prior to shipping and can be used as an official third point of closure. A red O-ring is installed on all PTCs to act as a visual warning indicator in the event of line failure. Caps fit all TODO-MATIC and TODO-Gas Tank Units.

TODO II Tank Units are the latest addition to the rail range that will eventually replace the TODO-MATIC line. This new product offers improved serviceability, pressure drop and design features that will speed up loading/ unloading times. With lower weight and virtually zero spillage, the TODO II represents the next generation for rail car fluid and gas transfer.
