Components for Harsh Service Conditions
PEEK is considered for downhole connectors, backup rings, seals, pump and valve components, sleeves and electrical parts because of its chemical, hydrolysis and temperature resistance. GUNUOFENG supplies stock shapes and accepts drawings for machined components, but suitability cannot be determined from material name alone.

Pressure, temperature, chemical composition, sour-gas exposure, load, time, decompression cycle, mating surface and sealing geometry all affect performance. Provide the applicable material or industry specification, dimensions, tolerances, quantity and documentation requirement. We will confirm what can be quoted.
Grade Considerations
Unfilled PEEK offers balanced toughness and chemical resistance. GF30 or CF30 may improve stiffness and dimensional stability, while fiber-filled grades sacrifice elongation. Bearing-grade formulations may help sliding systems but are available only after sourcing or customization review. No grade should be selected solely from a maximum-temperature headline.
The buyer remains responsible for qualification in pressure-containing, downhole or safety-critical equipment. Typical website figures are screening references and not guaranteed limits.
