How can HDPE pipes be connected to PVC pipes?

Since they are different materials, use a flanged connection with HDPE flange adaptors and backup flanges to connect to PVC flanges.

Product Q&A

Q:Which SDR of HDPE fittings should be used for SDR13.6-PN12.5 pipe?

To guarantee safety, fittings must have an equal or higher pressure rating. Use SDR13.6 or SDR11 fittings; SDR17 is not suitable for SDR13.6 pipelines.

Q:What types of HDPE fittings does SUNPLAST provide?

We provide HDPE butt fusion fittings (50-800mm), electrofusion fittings (20-630mm), and compression fittings (20-110mm).

Q:Can SUNPLAST provide HDPE fittings in PE80 material?

Yes, PE80 fittings are available upon request.

Q:Can HDPE fittings made of PE100 be welded with PE80 pipes?

Yes, they can be welded together. However, for the best results, we recommend welding PE80 pipes with PE80 fittings.

Q:Can HDPE fittings connect to PVC or PPR pipes?

No. Thermal plastic fittings can only connect to pipes of the same material grade. HDPE fittings cannot connect to PVC or PPR pipes via heat fusion.
