Can the CEJN Series 115/116/117/125 PVC Quick Coupling Plug Cap withstand exposure to hydraulic fluids and common workshop solvents?

CEJN Series 115/116/117/125 PVC Quick Coupling Plug Cap offers good general protection against dust, dirt and mechanical damage, but PVC has limited chemical resistance. It will tolerate brief contact with many common workshop fluids and light oils, but prolonged or repeated exposure to hydraulic fluids, strong solvents (e.g., ketones, chlorinated solvents), petrol/gasoline, hydraulic oils with aggressive additives or concentrated cleaners can cause softening, swelling, embrittlement or discoloration. For routine shop use (occasional splashes, light oil mist) the plug cap is acceptable; for regular immersion, heavy contamination with aggressive hydraulic fluids or frequent solvent cleaning, use a cap made from more chemically resistant material or verify compatibility with the specific fluid. If in doubt, test a sample or consult CEJN with the exact fluid specification.

Is the CEJN Series 115/116/117/125 PVC Quick Coupling Plug Cap suitable for outdoor use in UV and extreme temperature conditions?

CEJN Series 115/116/117/125 PVC Quick Coupling Plug Cap is made from durable PVC and provides effective protection against dust, dirt and mechanical damage, which helps preserve components when couplings are not in use. However, standard PVC has limited long‑term resistance to prolonged UV exposure and extreme temperature fluctuations. Extended sunlight (UV) can cause PVC to become brittle, fade or crack over time, and very high or very low temperatures can affect flexibility and sealing performance. Recommendation: - Short‑term outdoor use or occasional exposure is acceptable. - For continuous outdoor use in strong sunlight or severe temperature extremes, consider UV‑stabilized materials or plugs specifically rated for UV and wide temperature ranges, or provide additional protection (covering, shade, storage).
