Our flex-lip piston design has been engineered to withstand the demands of today’s high-pressure/ high-temperature drilling conditions. Manufactured in India CSS pistons feature a proprietary, abrasion-resistant urethane that is compatible with oil and water based drilling fluids. Along with this chemical compatibility, our urethane is rated for temperatures up to 300°F and pressures up to 7500 psi. 

Bull Nose is an extreme service piston with a bull-nose shape that has the benefits of a bull-nose piston, while also keeping some of the flexible leading-edge benefits of the Flex-Lip piston. This is a high performance urethane bonded piston designed for high pressure and higher temperature applications. This piston is designed with a Multi-durometer bonded urethane and a built in lubricant to reduce friction within the liner allowing for longer piston and liner life.
