Best Sealant for Plastic Threads

Wondering which glue to choose for plastic threads or plastic-metal threaded connections? Will popular anaerobic glues designed for metal pass the test when applied to plastic? In today's video, I put three products to the test to check which one provides the strongest and most leak-proof connection. The results might surprise you! Thread sealants and adhesives tested in this video: 🔹 KEMISKOL T548 – A high-strength anaerobic sealant, designed mainly for metal threads in hydraulics. Disassembly class: 3 (High Strength). 🔹 KEMISKOL T675 – A very strong anaerobic adhesive. Worth noting: in specific cases, when used with an activator, it can be applied to plastics. Disassembly class: 3. 🔹 KEMISPOX W21 – A two-component epoxy glue, specially developed for bonding and sealing plastic threads such as PVC or PP. After a series of tests, I have a clear favorite. The winner turned out to be KEMISKOL T548! You can successfully use it for screws made of PVC and PA. 🛒 You can buy the winning product here: https://ataszek.pl/1472-uszczelniacz-do-gwintow-hydraulicznych.html #threadsealant #plumbing #plasticthreads #diy #leakrepair #pvcglue #kemiskol #hydraulics
