Main Grades
KP501
Specially processed to incorporate a combination of natural & synthetic lubricants, KP501 is essentially without rival in the most difficult of bone-dry gas applications. Typically, pure elemental or hydrocarbon gases with dew points less than –40°C are candidates for KP501.
KP104
This filled polymeric material contains special fillers which enable all-round performance in a wide variety of applications. Can be used in both wet & dry gas applications, both lubricated & non-lubricated. Wear on mating surfaces is minimal with KP104.
KP109
KP109 is a specially formulated polymeric compound which gives outstanding performance in difficult wet, oxidizing gas applications. Provides excellent wear resistance in some of the most demanding applications such as high temperature / high pressure PET compressors. High creep & thermal distortion resistance make 9818 the perfect choice.
KP106
Our premium non-lube problem solver. KP106 is a polymer alloyed with high strength thermoplastic fillers, combined & manufactured to give particularly good creep & wear resistance in demanding non-lube gas applications. Best suited to hydrogen, hydrocarbon and mixed gases with varying gas dew points.
KP201
High temperature thermoplastic resin reinforced with wear resistant fibres. KP201 has the unique ability to operate at both the highest of pressures and in lube/non-lube environments. This material is used in a wide range of hydrocarbon gas applications, particularly where gases are sometimes dirty or where they have a dissolving effect on lubricants.
KP202
This premium grade is commonly used in high pressures, particularly where insufficient sealing or bearing elements have been provided. Due to it’s inherent strength properties, KP202 has the highest creep resistance, usually reserved for the most arduous lubricated applications.
