Severe service conditions are generated when the reservoir produces high levels of H2S and CO2 in the gas phase, and high chloride levels in water in the liquid phase. The chemicals can be very damaging to some valve lubricant and sealant formulations, which can cause the viscosity structure of the product to breakdown, or the product to change state from semi-solid to solid or fluid. RS Clare’s premium lubricants and sealants are formulated and tested to withstand extremely high levels of these severe produced chemicals. Chemical testing is conducted at pressures and temperatures representative of actual well environments. Alongside chemical stability, physical stability of the lubricant/sealant at high temperature and pressure is important. The RS Clare range has been evaluated to be stable at sustained temperatures up to 450°F, and has been field proven in wellhead valves with less than 10,000 psi Shut In Tubing Head Pressure.

The Valve Sealant 701 range was designed to further expand on the sealing performance that had been achieved with Valve Lubricant 601TM. Our non-hardening sealants provide temporary emergency repair to damaged valves so that operations can continue until replacement and maintenance can be scheduled.
RS Clare High-Performance Valve Lubricants

Our valve lubricants are effective  because they are resistant to hydrocarbons and other chemicals, which makes cleaning the valve all the more difficult as it’s primary job is to remain in the valve cavity. 

We offer a range of synthetic cleaning fluids specially formulated to remove hydrocarbon resistant lubricants.
