Treacle Cock

This treacle cock is of cast iron construction.  It has a precision fitted brass spring-loaded slide.  
There is even provision for padlocking. 
The most efficient way of controlling the flow of polyurethane, without leakage.  
Fits our 220ltr drums perfectly. 
Heat can be used to separate build up of polyurethane as all parts are made from steel and will not melt.
