Houghton type k is the Canadian equivalent of  Parks 50.
 This highly sought after quench oil gives consistent repeatable results in heat treatment of tool steels. 

This is a parks 50 equivalent oil.  Sold in 2 liter plastic easy pour jugs. 

• Fast cooling rate in the initial stage of quenching: Maximum metallurgical and physical properties
• Minimal drag-out of quenching oil: Less smoke and makeup required
• Excellent oxidation resistance and thermal stability: elimination of waste due to quench oil degradation
• 7-9 second oil
• Flash point at 345 F

Houghto-Quench K is an accelerated quenching oil suitable for use at temperatures up to 180°F (82°C). It is based upon specialty solvent refined paraffinic base oil to minimize oxidation and ensure consistent performance under the most arduous of operating conditions. A carefully formulated additive package is incorporated into Houghto-Quench K to reduce the duration of the vapor blanket cooling stage and provide accelerated quenching characteristics, together with excellent oxidation resistance and thermal stability.
