Manufactured from high-tensile alloy steel to ensure superior fatigue resistance, this spring is calibrated to provide optimal closing force. The surface is treated with a specialized coating to resist corrosion and chemical erosion from abrasive drilling fluids and proppants. Designed for a precise fit within FMC fluid end assemblies, this spring helps minimize pump vibration and noise. It is a critical component for ensuring long-term operational reliability in demanding oilfield environments.
