Kuraray Plastics Co., Ltd. (Headquarters: Osaka; President: Katsuhiko Kishi) has developed and begun marketing a new line of oil-resistant hoses made from a special, transparent polyvinyl chloride resin. The "Oil Queen" hose will go on sale July 20, and is expected to find a broad market for use in industrial and agricultural machinery.

Kuraray already markets the Kuraray Loop Hose brand of PVC delivery and suction hoses, which are used in a number of fields.

To the present, most oil-resistant hoses have been made of opaque black compounds that made it impossible to see the fouling of oil from the outside.
Now user preferences have changed and consumers come to want transparent, fouling-resistant suction hoses that allow them to see whether oil is depleted or dirty at a glance. The "Oil Queen" oil-resistant, transparent hose was developed from a special compound in response to this demand. Its characteristics of lightness, plasticity, and flexibility make it easy to use.

Product name: Kuraray Oil Queen DS-3 Loop Hose
