Product Q&A

Q:What is the main difference between uPVC pipe fittings and PVC pipe fittings?

PVC contains BPA and phthalates which make it flexible and potentially toxic for drinking water. uPVC is unplasticized, rigid, and free of toxic plasticizers, making it safe for drinking water transportation.

Q:Are uPVC pipe fittings UV-resistant?

Yes, the product contains UV stabilizing additives and thermal properties ensuring suitability for both interior and exterior environments.

Q:What is the installation process for uPVC gasketed fittings?

Steps include chamfering spigot ends, cleaning sockets and rings, inserting rubber rings, applying lubricant to spigots, and pushing spigots into sockets until the witness mark shows. Larger pipes may require a pipe puller.

Q:What is the warranty period for these fittings?

We provide a 5-year warranty for normal use.

Q:Can I get samples of the uPVC couplers?

Yes, samples are available but they are charged.
