Check the thread size to fit your male-threaded fixtures.
Choose 316 stainless steel thread for corrosive water.
Opt for ISO-certified couplings for quality assurance.
Ensure the coupling has a high-quality rubber gasket.
Avoid couplings with rough threads or uneven fusion ports.
Select the same brand as your PPR pipes for best fit.
Verify the fusion port is smooth and free of defects.
Installation Steps for Leak-Free Performance
Preheat the fusion machine to 260°C (500°F) before use.
Cut the PPR pipe squarely and deburr its end.
Clean the pipe end and coupling’s fusion port with a dry cloth.
Fuse the pipe into the coupling for 5-7 seconds (by size).
Hold the joint for 10 seconds to set the fusion bond.
Allow 30 minutes of air cooling before thread connection.
Wrap Teflon tape around the male thread (3-4 wraps).
Hand-tighten the male thread into the female coupling.
Use a wrench to gently tighten (do not over-tighten).
Test for leaks by turning on the water supply.
